Mycoplasma bovis (M. bovis) is considered to be one of the more pathogenic species of Mycoplasma and causes significant economic losses worldwide. Mycoplamsas cause severe clinical signs in cattle of all ages. M. bovis is the most frequent Mycoplasma pathogen found to cause pneumonia, mastitis, and arthritis in cattle and its etiological role has also been associated with otitis, keratoconjuctivitis, synovitis, and reproductive disorders in cows and bulls. In general, Mycoplasmas are difficult to treat since they lack a cell wall or membrane, which tends to make them resistant to several classes of commonly used broad-spectrum antibiotic treatments. Mycoplasmas differ from viruses in that Mycoplasmas are larger than most viruses and damage tissue cells by attaching to the surface of cells and destroying them, rather than by entering the cells. Animals infected with M. bovis have depressed immune responses and may exhibit signs of M. bovis infection such as fever, depression, anorexia, labored breathing, nasal and ocular discharge, coughing, sneezing, gasping, grunting, lameness and swollen joints, mastitis, middle ear infections, abortions, recumbence and death. The organism persists in unsanitary, warm, moist environments. Mycoplasmas may survive in milk, and even seem to thrive in the presence of large numbers of leukocytes, which are produced in response to the infection.
U.S. Pat. No. 6,548,069 discloses a vaccine composition that incorporates a whole cell inactivated bacterin containing at least two killed M. bovis strains and that an isolate may rapidly alter its antigens in culture. The patent teaches that high passage strains of greater than about 50 passages may lose infectivity and elicit a poorer immune response when used in a bacterin. It teaches use of a Mycoplasma strain which has been passed no more than about ten times or less before mass scale production because the antigens are believed to retain their natural state and thus will elicit a protective immune response against the infectious microorganism.
Killed M. bovis is not as effective or efficient as desired in lessening the severity of clinical symptoms associated with a Mycoplasma bovis infection. Even passage at a low level does not produce a Mycoplasma vaccine with high efficacy such that clinical symptoms are greatly reduced in animals when compared to animals not receiving such a vaccine. The few low passage, inactivated, M. bovis vaccines that are available do not show a large reduction in the severity of clinical symptoms in animals when compared to animals not receiving such vaccine.
The nature of the market requires that farmers be able to effectively immunize their animals for a wide variety of conditions in an efficient way. Other conditions that would be suitable for efficient immunization include, but are not limited to, Bovine viral diarrhea virus (BVDV), Parainfluenza-3 virus (PI-3), Bovine Respiratory Syncytial Virus (BRSV), Bovine Herpesvirus (BHV-1), Bovine rotavirus, Breda virus, a calici-like virus, Adenovirus, Astrovirus and Parvovirus, Mannheimia haemolytica (formerly Pasteurella haemolytica), Pasteurella multocida, Actinomyces (Arcanobacterium) pyogenes, Haemophilus somnus (reclassified as Histophilus somni), Chlamydiae, Bovine genital campylobacteriosis, Leptospirosis, Brucellosis, Clostridia, Escherichia coli, Cryptosporidium parvum, Mycobacterium avium paratuberculosis, Salmonella, Mycobacterium avium paratuberculosis, Cryptosporidiosis, mastitis, Dermatomycoses, lower respiratory tract infections, Trichomoniases, Neospora Canum, Babesiosis and the like.
There remains a need for an immunogenic composition effective for eliciting an immunological response against M. bovis for lessening the severity of or reducing the incidence of signs of M. bovis infection, and for reducing or eliminating the incidence of signs of M. bovis infection.
The present invention provides an immunogenic composition or vaccine which uses high passage attenuated M. bovis strains, such that signs of M. bovis infection and/or the M. bovis infection itself and/or incidence or severity, are reduced in animals receiving the immunogenic composition or vaccine as compared to those animals with infection by wild-type M. bovis strains. The immunological composition of the present invention provides rapid onset of protection and long-lasting protection to an animal in need thereof.
The invention provides for attenuated and avirulent strains or isolates of M. bovis which have been passaged at least 110 times that provoke or elicit an immune response when administered to an animal. According to another aspect, the present invention also relates to attenuated M. bovis bacteria having the same characteristics as the M. bovis bacteria strain deposited with the ATCC under accession numbers PTA-9666 and PTA-9667.
An M. bovis strain of the present invention, attenuated through multiple passage or serial attenuation as described above, may be used as a medicine, preferably as a veterinary medicine. Further, the attenuated M. bovis strains of the present invention may be used for the preparation of veterinary compositions, for the prophylaxis or treatment of infections caused by M. bovis in animals susceptible to infection by M. bovis.
Such an immunological composition would be suitable as either a one dose or two dose or multi-dose (initial dose followed by booster(s)) immunization regimen, an immunological composition suitable and convenient for administration by several routes, and an immunological composition that is compatible with other immunogens and immunological compositions for preparation of combination vaccines.
In another embodiment of the present invention, the M. bovis strains of the present invention may be combined with other medicaments, therapies or vaccines.
The present invention also provides for a method of making the immunogenic composition of the present invention. The method comprises obtaining a virulent strain of M. bovis and passaging said strain at least 110 times, such that it becomes attenuated and avirulent. The high passage strain may then be mixed with an additional components including but not limited to, pharmaceutically acceptable carriers, diluents, other medicaments, therapeutic compositions or vaccines, and combinations thereof.
The present invention also provides for a method of treatment or prophylaxis of animals having an M. Bovis infection to reduce signs of M. bovis infection, reduce the severity of or incidence of clinical signs of M. bovis infection, reduce the mortality of animals from M. bovis infection, and combinations thereof.
For purposes of the present invention, the terms “isolate” and “strain” are used interchangeably and that differences between individual strains or isolates may be detected using DNA fingerprinting (i.e. different strains or isolates will have differing fingerprints). For purposes of the present invention, the terms “vaccine” and “composition” are used interchangeably.
The following terms and expressions are used herein:
“Attenuation” means reducing the virulence of a pathogen. In the present invention “attenuation” is synonymous with “avirulent”. In the present invention, an attenuated bacterium is one in which the virulence has been reduced so that it does not cause clinical signs of a M. bovis infection but is capable of inducing an immune response in the target mammal, but may also mean that the clinical signs are reduced in incidence or severity in animals infected with the attenuated M. bovis in comparison with a “control group” of animals infected with non-attenuated M. bovis and not receiving the attenuated bacterium. In this context, the term “reduce/reduced” means a reduction of at least 10%, preferably 25%, even more preferably 50%, still more preferably 60%, even more preferably 70%, still more preferably 80%, even more preferably 90% and most preferably of 100% as compared to the control group as defined above. Thus, an attenuated, avirulent M. bovis strain is one that suitable for incorporation into an immunogenic composition comprising a modified live M. bovis bacterium.
“Diluents” may include water, saline, dextrose, ethanol, glycerol, and the like. Isotonic agents may include sodium chloride, dextrose, mannitol, sorbitol, and lactose, among others. Stabilizers include albumin and alkali salts of ethylendiamintetracetic acid, among others.
An “effective amount” for purposes of the present invention, means an amount of an immunogenic composition capable of inducing an immune response that reduces the incidence of or lessens the severity of M. bovis infection in an animal. Particularly, an effective amount refers to colony forming units (CFU) per dose. The preferred immunogenic composition or vaccine of the present invention has at least 1.0 E7 CFU of the live bacteria of the attenuated, avirulent M. bovis bacteria per dose, more preferably 8.4 E7 CFU or 9.4 E7 CFU of the live bacteria of the attenuated, avirulent M. bovis bacteria per dose. An example (but not meant to be limited to such example) of an effective amount would be an M. bovis vaccine administered via a simultaneous intranasal and subcutaneous route administered 2 times with a 2 week interval at a high dose level (1E9 CFU).
“High passage strain” as well as the term “passaged at least 110 times” for purposes of the present invention, refers to an M. bovis strain that has been passaged more than 110 times, more preferably, more than 115 times, more preferably, more than 120 times, even more preferably, more than 125, even more preferably, more than 130 times, more preferably, more than 133 times, even more preferably, more than 135 times, and still more preferably between 135 and 145 times, specifically more preferably more than 140 times, and more preferably more than 145 times, and further more preferably more than 150 times.
The term “having the characteristics as the M. bovis bacteria strain deposited with the ATCC under accession numbers PTA-9666 and PTA-9667” means that such a bacteria strain is attenuated, and is capable to reduce the mortality and euthanization rate in a group of animals of at least 83% as compared to a non-vaccinated control group of animals. Furthermore, the term also means that such a bacteria strain is attenuated, and is cable to reduce the mortality and euthanization rate in a group of animals at least 56% when compared to a non-vaccinated control group of animals after the administration of a single dose of said vaccine. Additionally, the term also means that such a bacteria strain is attenuated, and is cable to reduce the mortality and euthanization rate in a group of animals at least 65% when compared to a non-vaccinated control group of animals after the administration of a single dose of said vaccine.
An “immunogenic or immunological composition” refers to a composition of matter that comprises at least one antigen, which elicits an immunological response in the host of a cellular and/or antibody-mediated immune response to the composition or vaccine of interest. Usually, an “immunological response” includes but is not limited to one or more of the following effects: the production or activation of antibodies, B cells, helper T cells, suppressor T cells, and/or cytotoxic T cells and/or gamma-delta T cells, directed specifically to an antigen or antigens included in the composition or vaccine of interest. Preferably, the host will display either a therapeutic or protective immunological response such that resistance to new infection will be enhanced and/or the clinical severity of the disease reduced. Such protection will be demonstrated by either a reduction or lack of clinical signs normally displayed by an infected host, a quicker recovery time and/or a lowered duration or bacterial titer in the tissues or body fluids or excretions of the infected host.
The term “Immunogenic testing” means infecting cattle with the passaged M. bovis bacteria and monitoring the development of the humoral antibody response against M. bovis in the infected cattle.
The term “Improved efficacy such that clinical signs associated with M. bovis infection and/or the M. bovis infection itself were reduced in comparison to currently available vaccines when vaccinates are exposed to M. bovis or suffer infection by wild-type M. bovis strains” refers to a reduction in either the incidence of or severity of clinical signs of M. bovis infection when comparing vaccines made from strains passaged as taught by the present invention with M. bovis vaccines that were available prior to this invention. In this context, animals not vaccinated, or vaccinated with M. bovis vaccines available prior to the present invention will have clinical signs of M. bovis infection that are at least 30%, and possibly up to more preferably at least 40%, still more preferably at least 50%, even more preferably at least 60%, still more preferably at least 70%, even more preferably at least 75%, still more preferably at least 80%, even more preferably at least 85%, still more preferably at least 90%, and most preferably at least 95% more severe or prevalent than in animals receiving an administration of an M. bovis immunogenic composition in accordance with the present invention.
The term “in need of such administration” or “in need of such administration treatment”, means that the administration or treatment is associated with the boosting or improvement in health or any other positive medicinal effect on health of the animals which receive the immunogenic composition in accordance with the present invention.
The term “Long-lasting protection” refers to improved efficacy that persists for at least 3 weeks, but more preferably at least 6 months, still more preferably at least 1 year, even more preferably at least 2 years for beef animals, and at least 6 months, more preferably at least 1 year, still more preferably at least 2 years, still more preferably at least 3 years, and even more preferably at least 4 years for dairy animals. For both dairy animals and beef animals, it is most preferred that the long lasting protection shall persist until the average age at which beef animals are marketed for meat and the age at which dairy animals conclude their productive life of milking.
The term “Lung Pathology Assessment” refers to observation of the lungs after necropsy, including, but not limited to, assessment of consolidation, lesions, and nodular formations as well as assessment of the thoracic cavity including pleuritis and fluid accumulation.
The term “Mortality” refers to death caused by M. bovis infection. This includes the situation where the infection is so severe that an animal is euthanized to prevent suffering and provide a humane ending to their life.
The term “Signs of M. bovis infection” refers to the manifestations of infection or disease caused by M. bovis including both the clinical symptom(s) and pathology typically experienced by cattle infected with wild type M. bovis. These manifestations of infection or disease may take many forms including, but not limited to, fever, depression, anorexia, labored breathing, nasal and ocular discharge, coughing, sneezing, gasping, grunting, lameness and swollen joints, middle ear infections, discharge from inflammation of the inner ear, abortions and other reproductive disorders, recumbence, respiratory infection, head tilt, ataxia, arthritis, mastitis, otitis, keratoconjunctivitis, synovitis, pleuritis, lung lesions, lung consolidation and nodular formation in the lungs, increased synovial fluid, thickened joint capsules, and death.
The term a “veterinary acceptable carrier” “pharmaceutically acceptable carrier” or “carrier” includes any and all solvents, dispersion media, coatings, adjuvants, stabilizing agents, diluents, preservatives, antibacterial and antifungal agents, isotonic agents, adsorption delaying agents, and the like. In some preferred embodiments, and especially those that include lyophilized immunogenic compositions, stabilizing agents for use in the present invention include stabilizers for lyophilization or freeze-drying.
The present invention provides an immunogenic composition or vaccine which overcomes the problems inherent in previous vaccines and provides a safe, efficacious vaccine utilizing high passage attenuated M. bovis strains, such that signs of M. bovis infection and/or the M. bovis infection itself and/or incidence or severity, are reduced in animals receiving the immunogenic composition or vaccine comparison with infection by wild-type M. bovis strains. Additionally, the lethal effect of M. bovis is reduced when the immunogenic composition of the present invention is administered to an animal (e.g., calves given a vaccine in accordance with the present invention are at a lower risk of developing signs of M. bovis infection, as well as death associated with M. bovis infection, and any clinical signs that result would be less severe or prevalent than in animals not receiving any vaccine, but were infected with M. bovis or receiving a vaccine not in accordance with the present invention).
Additionally, herds would experience a smaller number of infected and deceased animals in a herd when animals are administered the vaccine in accordance with the present invention as compared to non-vaccinated but infected animals, and preferably even as compared to animals vaccinated with conventionally available vaccine(s). The high passage, attenuated strains of the present invention provide added efficacy when compared to other vaccines currently on the market.
The present invention provides for attenuated and avirulent strains or isolates of M. bovis which have been passaged at least 110 times that provoke or elicit an immune response when administered to an animal. Advantageously, such attenuated and avirulent strains or isolates of M. bovis which have been passaged at least 110 times provokes or elicits an immune response that protects the animals receiving the immunogenic composition of the present invention and reduces the risk of the animals dying or having to be euthanized as a result of M. bovis infection. The immunogenic composition also has the benefit of reducing the number of animals in a herd experiencing death or euthanasia as a result of M. bovis infection. Further, the composition has been shown to lessen the incidence and severity of clinical signs of M. bovis infections in individual animals and herds.
In one embodiment, an immunogenic composition is disclosed which comprises one or more high passage M. bovis strain(s) which have been passaged at least 110 times and a pharmaceutically acceptable carrier. The immunogenic composition of the present invention elicits an immune or immunogenic response against M. bovis infection in animals, and preferably cattle. Generation of the immunogenic response has the effect of lessening the incidence and severity of clinical signs of M. bovis infection as well as reducing mortality and euthanization as a result of M. bovis infection.
Another embodiment provides for a method of making the immunogenic composition of the present invention. The method comprises obtaining a virulent strain of M. bovis and passaging said strain at least 110 times, such that it becomes attenuated and avirulent. The high passage strain may optionally then be mixed with additional components including but not limited to, adjuvants, pharmaceutically acceptable carriers, diluents, and combinations thereof. The method generally comprises (a) passaging M. bovis bacteria more than 110 times to produce a cultured M. bovis bacteria; (b) obtaining the cultured M. bovis bacteria; and (c) propagating the non-pathogenic, but immunogenic M. bovis bacteria to obtain the attenuated M. bovis bacteria.
In preferred forms of this method, an additional step of testing the cultured M. bovis bacteria obtained under step (b) for its pathogenicity and immunogenicity. Preferably, this step is done prior to step (c). Pathogenicity testing comprises infecting cattle with the passaged M. bovis bacteria and monitoring the infected cattle for developing clinical symptoms of an M. bovis infection.
The present invention also provides for a method of reducing the incidence of death or euthanasia resulting from M. bovis infection in an individual cow or within a herd of cattle. The method comprises administration of a high passage strain of M. bovis, passaged at least 110 times, to a bovine. The immunogenic composition of the present invention has been shown to reduce mortality in cattle and in herds when compared to those animals not receiving a vaccine as well as compared to those strains passaged less than 110 times. Preferably, mortality in cattle and in herds is reduced by at least 10%, more preferably, mortality is reduced by at least 20%, even more preferably, mortality is reduced by at least 25%, more preferably, mortality is reduced by at least 30%, even more preferably, mortality is reduced by at least 40%, still more preferably, mortality is reduced by at least 50%, even more preferably, mortality is reduced by at least 56%, still more preferably mortality is reduced by at least 60%, even more preferably, mortality is reduced by at least 70%, still more preferably, mortality is reduced by at least 75%, even more preferably, mortality is reduced by at least 80%, still more preferably, mortality is reduced by at least 83%, and, most preferably, mortality is reduced by at least 90% as compared to those animals not receiving a vaccine.
Additionally, mortality in cattle and in herds is reduced by at least 10%, more preferably, mortality is reduced by at least 20%, even more preferably, mortality is reduced by at least 25%, more preferably, mortality is reduced by at least 30%, even more preferably, mortality is reduced by at least 40%, still more preferably, mortality is reduced by at least 48% as compared to those strains passaged less than 110 times as compared to other M. bovis stains, including for example, M. bovis bacteria strains deposited with the ATCC under accession numbers PTA-8694; PTA 8695; or PTA 8696.
Another embodiment includes a method for the treatment or prophylaxis of infections caused by M. bovis. The method comprises administering an effective amount of the immunogenic composition of the present invention to an animal, wherein said treatment or prophylaxis is selected from the group consisting of reducing signs of M. bovis infection, reducing the severity of or incidence of clinical signs of M. bovis infection, reducing the mortality of animals from M. bovis infection, and combinations thereof.
A further embodiment includes a method of reducing the incidence and/or severity of clinical symptoms of M. bovis infection. The method generally comprises administration of a high passage strain of M. bovis, passaged at least 110 times, to animals, preferably cattle. More particularly, the method may be used to reduce lung consolidation due to M. bovis infection. The effectiveness of the administration of a high passage strain of M. bovis to an animal in need thereof may be verified in a number of conventional ways, including lung pathology assessment. Preferably, lung pathology assessment, specifically the percentage of lung consolidation attributed to lesions due to M. bovis as customarily scored for various species may be made post-necropsy. Still more preferably, such lung pathology will be reduced when compared to the non-vaccinated group, by at least 33%, more preferably at least 50%, even more preferably at least 70%, still more preferably at least 80%, even more preferably at least 90%, and most preferably by at least 95%.
A surprising result of the present invention found that further passaging of the M. bovis strain led to increased efficacy of the vaccine. When results of efficacy studies for previous high passage strains, i.e. those passaged less than 110 times (e.g., M. bovis bacteria strains deposited with the ATCC under accession numbers PTA-8694; PTA 8695 or PTA 8696), were compared to the results of those studies using the higher passage strain of the present invention, it was surprisingly found that there was a reduction in mortality or euthanasia for humanitarian reasons for cattle resulting from M. bovis infection using the strain of the present invention.
It was an additionally surprising result that administration of one dose of the higher passaged strain of the present invention was as or more efficient and efficacious as the two dose administration of the previous high passage strain, passaged less than 110 times, in reducing of the number of cattle experiencing death or euthanasia as a result of M. bovis infection. While a reduction in mortality of about 56%, as compared to a non-vaccinated animals, was provided by a single administration of the attenuated M. bovis strains of the present invention passaged more than 110 times, two administrations of attenuated M. bovis strains passaged not more 106 times were needed to obtain the same reduction in mortality.
In a preferred embodiment, the high passage strain of M. bovis is passaged at least 110 times in vitro in cell culture, more preferably, between 110 times and 200 times, even more preferably, between about 110 and 180 times, still more preferably, at least 115 times, even more preferably at least 120 times, still more preferably, between 120 and 170 times, even more preferably at least 125 times, still more preferably between 125 and 160 times, even more preferably, at least 130 times, still more preferably, between 130 and 150 times, even more preferably at least 131 times, more preferably, at least 132 times, even more preferably, at least 133 times, more preferably, at least 134 times, and even more preferably, at least 135 times, and most preferably between 135 and 145 times.
The strains of M. bovis useful in the vaccine or immunogenic composition may be any strain or isolate of M. bovis having the same properties like inventive strains as described herein. Representative strains include those deposited with the ATCC in Manassas, Va. on Dec. 18, 2008, under the terms of the Budapest Treaty and designated as ATCC deposit numbers PTA-9666 and PTA-9667. These strains are pathogenic prior to passaging, but after passaging the strain as described above, and particularly after passaging more than 110 times, the resultant passaged strains were attenuated, avirulent, and produced an immune response in an animal receiving an administration of the immunogenic composition of the strain. In particular, these strains led to increased efficacy and show a reduced mortality in cattle and in herds when used as a modified live vaccine. Advantageously, the vaccine or immunogenic composition of the present invention utilizing such deposited strains exhibited effective cross-protection against M. bovis strains other than the strain passaged to attenuation and then used as an antigenic component.
Combination Compositions
In another embodiment of the present invention, the M. bovis strains of the present invention may be combined with other medicaments, therapies or vaccines. Conditions that would be suitable for efficient immunization include, but are not limited to, Bovine viral diarrhea virus (BVDV), Parainfluenza-3 virus (PI-3), Bovine Respiratory Syncytial Virus (BRSV), Bovine Herpesvirus (BHV-1), Bovine rotavirus, Breda virus, a calici-like virus, Adenovirus, Astrovirus and Parvovirus, Mannheimia haemolytica (formerly Pasteurella haemolytica), Pasteurella multocida, Actinomyces (Arcanobacterium) pyogenes, Haemophilus somnus (reclassified as Histophilus somni), Chlamydiae, Bovine genital campylobacteriosis, Leptospirosis, Brucellosis, Clostridia, Escherichia coli, Cryptosporidium parvum, Mycobacterium avium paratuberculosis, Salmonella, Mycobacterium avium paratuberculosis, Cryptosporidiosis, mastitis, Dermatomycoses, lower respiratory tract infections, Trichomoniases, Neospora Canum, Babesiosis and the like.
Bovine viral diarrhea virus (BVDV) type 1 (BVDV-1) and type 2 (BVDV-2) cause bovine viral diarrhea (BVD) and mucosal disease (MD) in cattle (Baker, 1987; Moennig and Plagemann, 1992; Thiel et al., 1996, hereby entirely incorporated by reference). The division of BVDV into 2 serotypes is based on significant differences at the level of genomic sequences (summarized in Heinz et al., 2000, hereby entirely incorporated by reference) which are also obvious from limited cross neutralizing antibody reactions (Ridpath et al. 1994, entirely incorporated by reference). Inactivation of the RNase activity residing within the Erns results in an attenuated apathogenic BVDV which may be used as a modified live vaccine (WO 99/64604, hereby entirely incorporated by reference). The international patent application WO2005/111201 (hereby entirely incorporated by reference) provides a further generation of an attenuated BVDV suitable for MLV vaccines, which comprises a multiple modified BVDV having at least one mutation in the coding sequence for glycoprotein Erns and at least another mutation in the coding sequence for Npro, wherein said mutation in the coding sequence for glycoprotein Erns leads to inactivation of RNase activity residing in Erns and/or said mutation in the coding sequence for Npro leads to inactivation of said Npro. Furthermore, various conventional attenuated BVDV viruses are known in the art, which are also suitable candidates for vaccine development.
Parainfluenza-3 virus (PI-3) is an RNA virus classified in the paramyxovirus family. Infections caused by PI-3 are common in cattle. Although PI-3 is capable of causing disease, it is usually associated with mild to subclinical infections. The most important role of PI-3 is to serve as an initiator that may lead to the development of secondary bacterial pneumonia. Clinical signs include pyrexia, cough, serous nasal and lacrimal discharge, increased respiratory rate, and increased breath sounds. The severity of clinical signs worsen with the onset of bacterial pneumonia. Fatalities from uncomplicated PI-3 pneumonia are rare. Lesions include cranioventral lung consolidation, bronchiolitis, and alveolitis with marked congestion and haemorrhage. Inclusion bodies may be identified. Most fatal cases will also have a concurrent bacterial bronchopneumonia.
Bovine Respiratory Syncytial Virus (BRSV) is an RNA virus classified as a pneumovirus in the paramyxovirus family. In addition to cattle, sheep and goats may also be infected by respiratory syncytial viruses. This virus was named for its characteristic cytopathic effect—the formation of syncytial cells. BRSV is distributed worldwide, and the virus is indigenous in the cattle population. BRSV infections associated with respiratory disease occur predominantly in young beef and dairy cattle. Passively derived immunity does not appear to prevent BRSV infections but will reduce the severity of disease. Initial exposures to the virus are associated with severe respiratory disease; subsequent exposures result in mild to subclinical disease. BRSV appears to be an important virus in the bovine respiratory disease complex because of its frequency of occurrence, predilection for the lower respiratory tract, and its ability to predispose the respiratory tract to secondary bacterial infection. In outbreaks, morbidity tends to be high, and case fatality may be 0-20%. Signs include increased rectal temperature 40-42° C., depression, decreased feed intake, increased respiratory rate, cough, and nasal and lacrimal discharge. Generally, respiratory signs predominate. Dyspnea may become pronounced in the later stages of the disease. Subcutaneous emphysema is sometimes reported. Secondary bacterial pneumonia is a frequent occurrence. A biphasic disease pattern has been described but is not consistent. Gross lesions include a diffuse interstitial pneumonia with subpleural and interstitial emphysema along with interstitial edema. These lesions are similar to and must be differentiated from other causes of interstitial pneumonia. Histologic examination reveals syncytial cells in bronchiolar epithelium and lung parenchyma, intracytoplasmic inclusion bodies, proliferation and/or degeneration of bronchiolar epithelium, alveolar epithelialization, edema, and hyaline membrane formation.
Bovine Herpesvirus (BHV-1) is associated with several diseases and symptoms in cattle: Infectious bovine rhinotracheitis (IBR), infectious pustular vulvovaginitis (IPV), balanoposthitis, conjunctivitis, abortion, encephalomyelitis, and mastitis. Only a single serotype of BHV-1 is recognized; however, three subtypes of BHV-1 have been described on the basis of endonuclease cleavage patterns of viral DNA. These types are referred to as BHV-1.1 (respiratory subtype), BHV-1.2 (genital subtype), and BHV-1.3 (encephalitic subtype). Recently, BHV-1.3 has been reclassified as a distinct herpesvirus designated BHV-5. BHV-1 infections are widespread in the cattle population. In feedlot cattle, the respiratory form is most common. The viral infection alone is not life-threatening but predisposes cattle to secondary bacterial pneumonia, which may result in death. In breeding cattle, abortion or genital infections are more common. Genital infections may occur in bulls (infectious pustular balanoposthitis) and cows (IPV) within 1-3 days of mating or close contact with an infected animal. Transmission may occur in the absence of visible lesions and through artificial insemination with semen from subclinically infected bulls. Cattle with latent BHV-1 infections generally show no clinical signs when the virus is reactivated, but they do serve as a source of infection for other susceptible animals and thus perpetuate the disease. The incubation period for the respiratory and genital forms is 2-6 days. In the respiratory form, clinical signs range from mild to severe, depending on the presence of secondary bacterial pneumonia. Clinical signs include pyrexia, anorexia, coughing, excessive salivation, nasal discharge that progresses from serous to mucopurulent, conjunctivitis with lacrimal discharge, inflamed nares (hence the common name “red nose”), and dyspnea if the larynx becomes occluded with purulent material. Pustules may develop on the nasal mucosa and later form diphtheritic plaques. Conjunctivitis with corneal opacity may develop as the only manifestation of BHV-1 infection. In the absence of bacterial pneumonia, recovery generally occurs 4-5 days after the onset of clinical signs. Abortions may occur concurrently with respiratory disease but may also occur up to 100 days after infection. Abortions may occur regardless of the severity of disease in the dam. Abortions generally occur during the second half of pregnancy, but early embryonic death may also occur. The first signs of genital infections in cows are frequent urination, elevation of the tailhead, and a mild vaginal discharge. The vulva is swollen, and small papules, then erosions and ulcers, are present on the mucosal surface. If secondary bacterial infections do not occur, animals recover in 10-14 days. If bacterial infection occurs, there may be inflammation of the uterus and transient infertility, with purulent vaginal discharge for several weeks. In bulls, similar lesions occur on the penis and prepuce. BHV-1 infection may be severe in young calves and cause a generalized disease. Pyrexia, ocular and nasal discharges, respiratory distress, diarrhea, incoordination, and eventually convulsions and death may occur in a short period after generalized viral infection. IBR is rarely fatal in cattle unless complicated by bacterial pneumonia. In uncomplicated IBR infections, most lesions are restricted to the upper respiratory tract and trachea. Petechial to ecchymotic hemorrhages may be found in the mucous membranes of the nasal cavity and the paranasal sinuses. Focal areas of necrosis develop in the nose, pharynx, larynx, and trachea. The lesions may coalesce to form plaques. The sinuses are often filled with a serous or serofibrinous exudate. As the disease progresses, the pharynx becomes covered with a serofibrinous exudate, and blood-tinged fluid may be found in the trachea. The pharyngeal and pulmonary lymph nodes may be acutely swollen and hemorrhagic. The tracheitis may extend into the bronchi and bronchioles; when this occurs, epithelium is sloughed in the airways. The viral lesions are often masked by secondary bacterial infections. In young animals with generalized BHV-1 infection, erosions and ulcers overlaid with debris may be found in the nose, esophagus, and forestomachs. In addition, white foci may be found in the liver, kidney, spleen, and lymph nodes. Aborted fetuses may have pale, focal, necrotic lesions in all tissues, but which are especially visible in the liver.
A number of other Bovine Respiratory Viruses have been identified as being involved in BRD. Bovine herpesvirus-4 has been implicated in several diseases, including BRD. Bovine adenovirus has been associated with a wide spectrum of diseases, with bovine adenovirus type 3 being the serotype most often associated with BRD. Two serotypes of bovine rhinovirus have been recognized to cause respiratory tract infections in cattle. Other viruses reported to be associated with BRD include bovine reovirus, enterovirus, and coronavirus. These viruses have a role similar to the other viruses previously discussed in that, in combination with other stressors, they may serve as initiators of bacterial pneumonia. Bovine coronavirus is also commonly associated with diarrhea in calves. It replicates in the epithelium of the upper respiratory tract and in the enterocytes of the intestine, where it produces similar lesions to rotavirus but also infects the epithelial cells of the large intestine to produce atrophy of the colonic ridges. Vaccines are not available for prevention of these viral respiratory diseases.
Bovine rotavirus is the most common viral cause of diarrhea in calves. Group A and B rotavirus are involved, but group A is the most prevalent and clinically important and contains several serotypes of differing virulence. Rotavirus replicates in the mature absorptive and enzyme-producing enterocytes on the villi of the small intestine, leading to rupture and sloughing of the enterocytes with release of virus to infect adjacent cells. Rotavirus does not infect the immature cells of the crypts. With virulent strains of rotavirus, the loss of enterocytes exceeds the ability of the intestinal crypts to replace them; hence, villous height is reduced, with a consequent decrease in intestinal absorptive surface area and intestinal digestive enzyme activity.
Other viruses, including Breda virus, a calici-like virus, Adenovirus, Astrovirus and Parvovirus, have been demonstrated in the feces of calves with diarrhea and may produce diarrhea in calves experimentally. However, these agents may also be demonstrated in the feces of healthy calves. The importance of these agents in the syndrome of neonatal diarrhea has yet to be determined. Mannheimia haemolytica (formerly Pasteurella haemolytica) biotype A, serotype 1 is the bacterium most frequently isolated from the lungs of cattle with BRD. Although less frequently cultured than M. haemolytica, Pasteurella multocida is also an important cause of bacterial pneumonia. When pulmonary abscessation occurs, generally in association with chronic pneumonia, Actinomyces (Arcanobacterium) pyogenes is frequently isolated. Under normal conditions, M. haemolytica generally remains confined to the upper respiratory tract, in particular the tonsillar crypts, and is difficult to culture from healthy cattle. After stress or viral infection, the replication rate of M. haemolytica in the upper respiratory tract increases rapidly, as does the likelihood of culturing the bacterium. The increased bacterial growth rate and colonization of the lungs may be due to suppression of the host's defense mechanism related to environmental stressors or viral infections. It is during this log phase of growth that virulence factors are elaborated by M. haemolytica, such as an exotoxin that has been referred to as leukotoxin. The interaction between the virulence factors of the bacteria and host defenses results in tissue damage and development of pneumonia. Clinical signs of bacterial pneumonia are often preceded by signs of viral infection of the respiratory tract. With the onset of bacterial pneumonia, the severity of clinical signs increases and are characterized by depression and toxemia. There will be pyrexia (40-41° C.); serous to mucopurulent nasal discharge; moist cough; and a rapid, shallow respiratory rate. Auscultation of the cranioventral lung field reveals increased bronchial sounds, crackles, and wheezes. In severe cases, pleurisy may develop, which is characterized by an irregular breathing pattern and grunting on expiration. The animal will become unthrifty in appearance if the pneumonia becomes chronic, which is usually associated with the formation of pulmonary abscesses. M. haemolytica causes a severe, acute fibrinous pneumonia or fibrinonecrotic pneumonia. The pneumonia has a bronchopneumonic pattern. Grossly, there is extensive reddish black to greyish brown cranioventral regions of consolidation with gelatinous thickening of interlobular septa and fibrinous pleuritis. There are extensive thromboses, foci of lung necrosis, and limited evidence of bronchitis and bronchiolitis. P. multocida is associated with a less fulminating fibrinous to fibrinopurulent bronchopneumonia. In contrast to M. haemolytica, P. multocida is associated with only small amounts of fibrin exudation, some thromboses, limited lung necrosis, and suppurative bronchitis and bronchiolitis.
Haemophilus somnus (recently reclassified as Histophilus somni) is being increasingly recognized as an important pathogen in BRD; these bacteria are normal inhabitants of the nasopharynx of cattle. H. somnus infection of the lungs results in purulent bronchopneumonia that may be followed by septicemia and infection of multiple organs. Occasionally, H. somnus is associated with extensive pleuritis. H. somnus may cause an acute, usually fatal, septicemic disease that may involve the nervous, musculoskeletal, circulatory, and respiratory systems, either singly or together. The reproductive system is often affected but usually without the other systems being clinically involved. The disease may be characterized by fever, severe depression, ataxia, weakness, blindness, coma, and death within several hours to several days. It occurs sporadically in individual beef and dairy cattle and is found nearly worldwide. H. somnus is a gram-negative, nonmotile, nonsporeforming, pleomorphic coccobacillus that requires an enriched medium and a microaerophilic atmosphere for culture. It appears to be identical to Histophilus ovis and Haemophilus agni, etiologic agents of ovine septicemia, mastitis, and epididymitis; however, transmission of H. somnus between sheep and cattle has not been demonstrated. Pathogenic and nonpathogenic strains have been differentiated by intracisternal inoculation of young calves with organisms from various sources. Pathogenic and nonpathogenic strains of H. somnus are carried in the sheath and prepuce of males, the vagina of female cattle, and in the nasal passages of both sexes. The organism may colonize the respiratory tract, presumably after inhalation, and is frequently found in urine. Prevalence of the organism in cattle is probably high because high titers of specific antibodies are found in a large proportion of tested cattle. Several disease syndromes caused by H. somnus have been recognized, including thrombomeningoencephalitis, fibrinopurulent bronchopneumonia, fibrinous pleuritis, and polyarthritis. Myocardial and skeletal muscle necroses occur. Suppurative vaginitis, cervicitis, and endometritis have been documented in cows infected experimentally and naturally after breeding, and the organism is a cause of sporadic abortion. Strains of H. somnus that cause disease adhere to the endothelium of vessels, resulting in contraction, exposure of collagen, platelet adhesion, and thrombosis. TME results when this occurs in the brain and associated membranes, after invasion of the organism into the bloodstream of susceptible cattle. Strains may adhere to endothelium in vessels of the pleura, myocardium, synovium, or a variety of other tissues and produce inflammation in those sites (e.g., infections of the larynx and middle ear have been recorded). The susceptibility of individual animals and variations in the preference of strains of the organism for vessels in different tissues may be important in the development of the form of disease, but the mechanisms involved are incompletely understood. Reproductive problems may not necessarily be preceded by bacteremia, but the pathogenesis is poorly defined. A fever as high as 42° C. is often the first sign of disease; however, this usually falls to normal or subnormal within hours. Other findings are determined by the system(s) involved and may include rapid respiration, stiffness, knuckling at the fetlocks, severe depression, ataxia, paralysis, and opisthotonos, followed by coma and death within several hours. Affected animals may be blind, and retinal hemorrhages with grey foci of retinal necrosis are sometimes seen. Signs such as hypersensitivity, convulsions, excitement, nystagmus, and circling occur inconsistently and may be related to the regions of the CNS affected in the course of disease development. Occasionally, animals are found dead, indicating a rapidly fatal course. A marked change in the total and differential WBC count is common; leukopenia and neutropenia occur in severe, usually acute, fatal disease, while neutrophilia may be present in less severe disease. In TME, the total cell count of the CSF is markedly increased, and neutrophils predominate. During septicemia, the organism may be recovered from blood, synovial fluid, CSF, brain, kidneys, urine, and a variety of other organs. The lesions are characterized by vascular thrombosis and infarction of the surrounding tissue. Randomly distributed red to brown foci of necrosis with hemorrhage on the surface and cut sections of the brain and spinal cord, retina, skeletal muscle, myocardium, kidney, intestine, and spleen are characteristic. A fibrinopurulent meningitis with cloudy CSF may sometimes be seen on the surface of the brain and spinal cord, and a polyserositis, especially of joints and pleura, may occur. An acute fibrinous bronchopneumonia with tissue necrosis may develop after airborne infections.
Except for M. bovis, the exact role of mycoplasmas and ureaplasmas in BRD requires better definition. Mycoplasmas may be recovered from the respiratory tract of nonpneumonic calves, but the frequency of isolation is greater in those with respiratory tract disease. The mycoplasmas commonly recovered from the lungs of pneumonic calves include Mycoplasma dispar, Ureaplasma spp. Experimental infections usually result in unapparent to mild signs of respiratory disease. This does not preclude a synergistic role for mycoplasmas in conjunction with viruses and bacteria in BRD. Lesions described include peribronchial and peribronchiolar lymphoid cuffing and alveolitis. Culture of these organisms requires special media and conditions and may take up to a week for growth of the organisms.
Chlamydiae have been identified in various parts of the world as a cause of enzootic pneumonia in calves. The causative agent is Chlamydia psittaci. Some respiratory isolates from calves have properties of immunotypes 1 and 6 and are similar to strains recovered from intestinal infections and abortions of cattle and sheep. Immunotype 6 has been recovered from pneumonic lungs of calves and pigs. Thus, the GI tract must be considered as an important site in the pathogenesis of chlamydial infections and as a natural reservoir and source of the organisms. Chlamydial pneumonia has affected calves under a whole range of conditions, including dairy farms. A synergism between Chlamydia and P. haemolytica has been demonstrated experimentally. Calves with chlamydial pneumonia are usually febrile, lethargic, and dyspneic, and have a serous and later mucopurulent nasal discharge and a dry hacking cough. Calves of weanling age are affected most frequently, but older cattle may also show signs of infection. The acute pulmonary lesion is a bronchointerstitial pneumonia. The anteroventral parts of the lungs are affected but, in severe cases, entire lobes may be involved. The dry cough is attributed to tracheitis. Microscopic changes in the lungs include suppurative bronchitis and alveolitis progressing to type II pneumocyte hyperplasia and interstitial thickening.
Bovine genital campylobacteriosis is a venereal disease of cattle characterized primarily by early embryonic death, infertility, a protracted calving season, and occasionally, abortion. Distribution is probably worldwide. The cause is the motile, gram-negative, curved or spiral, polar flagellated bacterium Campylobacter fetus venerealis or Campylobacter fetus fetus. For many years, it was thought that C. fetus fetus (formerly C. fetus intestinalis) was generally an intestinal organism, only occasionally caused abortion in cattle, and was not a cause of infertility. However, it has been shown that C. fetus fetus may also be a significant cause of the classic infertility syndrome usually attributed to Campylobacter fetus venerealis. There are several strains of C. fetus fetus, and the only way to determine if a strain is a cause of infertility is to test that possibility in a group of heifers. Campylobacter spp are very labile and are destroyed quickly by heating, drying, and exposure to the atmosphere. Unless cultured quickly after collection from the animal and grown under microaerophilic or anaerobic conditions, campylobacters will not grow. Campylobacter fetus is transmitted venereally and also by contaminated instruments, bedding, or by artificial insemination using contaminated semen. Individual bulls vary in their susceptibility to infection because some become permanent carriers, while others appear to be resistant to infection. Bulls may also transmit the infection mechanically for several hours after copulating with an infected cow. In cows, the duration of the carrier state is also variable; some clear the infection rapidly, while others may carry C. fetus for ≧2 yr. IgA antibodies are shed in cervical mucus in significant amounts in ˜50% of cows for several months after infection and are useful diagnostically. Although most of the genital tract may be free of infection when a cow eventually conceives, the vagina may remain chronically infected, even through pregnancy. Cows are systemically normal, but there is are variable degrees of mucopurulent endometritis that causes early embryonic death, prolonged luteal phases, irregular estrous cycles, repeat breeding and, as a result, protracted calving periods. Observed abortions are not common. In herds not managed intensively, disease may be noticed only when pregnancy examinations reveal low or marginally low pregnancy rates but, more importantly, great variations in gestation lengths, especially when the disease has recently been introduced to the herd. In subsequent years, infertility is usually confined to replacement heifers and a few susceptible cows. Bulls are asymptomatic and produce normal semen.
Leptospirosis is a contagious disease of animals, including man, caused by various immunologically distinct leptospiral serovars, most of which are regarded as subgroups of Leptospira interrogans. Infections may be asymptomatic or cause various signs, including fever, icterus, hemoglobinuria, renal failure, infertility, abortion, and death. After acute infection, leptospires frequently localize in the kidneys or reproductive organs and are shed in the urine, sometimes in large numbers for months or years. Because the organisms survive in surface waters for extended periods, the disease is often waterborne.
In the U.S. the disease is primarily due to the serovars Leptospira hardjo, Leptospira interrogans serovar hardjo (hardjo Prajitno), L. borgpetersenii serovar hardjo (hardjo Bovis), Leptospira pomona, and Leptospira grippotyphosa. However, Leptospira canicola and Leptospira icterohaemorrhagiae serovars also have been isolated. Calves may have fever, anorexia, and dyspnea, and in Leptospira pomona infections, icterus, hemoglobinuria, and anemia. Body temperature may rise suddenly to 40.5-41° C. Hemoglobinuria rarely lasts longer than 48-72 hrs. Icterus clears rapidly and is followed by anemia. The RBC's begin to increase in number by 4-5 days and return to normal 7-10 days later. However, Leptospira hardjo infections usually do not cause hemolytic anemia, which makes diagnosis more difficult. Morbidity and mortality are higher in calves than in adult cattle. In older cattle, signs vary greatly and diagnosis is more difficult. Enzootic Leptospira hardjo infections, which usually result in abnormal milk, are more obvious in dairy than in beef cattle. Signs usually are restricted to lowered milk and calf production; a hemolytic crisis does not occur. The milk is thick, yellow, and blood-tinged; it may contain clots, although there is little evidence of mammary inflammation. Milk production returns to normal in 10-14 days, even in the absence of treatment. Abortion and stillbirths, which are common in Leptospira pomona infections and sporadic in Leptospira hardjo infections, generally occur 3-10 weeks after initial infection. The abortions are more common during the third trimester. An abortion storm in a breeding herd is often the first indication that leptospirosis exists, because the mild initial signs often pass unnoticed. In endemically infected herds, abortions occur mostly in younger animals and are sporadic, rather than being manifested as abortion storms. Calves reared by previously infected cows are protected by colostral antibodies for up to 6 months. The calves generally have an antibody titer similar to that of their dams. In the acute form, anemia, icterus, hemoglobinuria, and submucosal hemorrhages are prominent. The kidneys are swollen, with multifocal petechial and ecchymotic hemorrhages that become pale with time. The liver may be swollen, with minute areas of focal necrosis. Petechiae in other organs are seen in fulminating cases; however, in the more prevalent Leptospira hardjo infections, the lesions are primarily restricted to the kidneys.
Brucellosis is caused by bacteria of the genus Brucella and is characterized by abortion, retained placenta, and to a lesser extent, orchitis and infection of the accessory sex glands in males. The disease in cattle, water buffalo, and bison is caused almost exclusively by Brucella abortus; however, Brucella suis or Brucella melitensis is occasionally implicated in some cattle herds. Brucella suis does not appear to be contagious from cow to cow. Brucella abortus Infection spreads rapidly and causes many abortions in unvaccinated herds. Typically, in a herd in which disease is endemic, an infected cow aborts only once after exposure; subsequent gestations and lactations appear normal. After exposure, many cattle become bacteremic for a short period and develop agglutinins and other antibodies; others resist infection, and a small percentage of infected cows recover. A positive serum agglutination test usually precedes abortion or a normal parturition but may be delayed in ˜15% of animals. The incubation period may be variable and is related to the stage of gestation at the time of exposure. Organisms are shed in milk and uterine discharges, and the cow may become temporarily sterile. Bacteria may be found in the uterus during pregnancy, uterine involution, and infrequently, for a prolonged time in the nongravid uterus. Shedding from the vagina largely disappears with reduction of the fluids after parturition. Some infected cows that aborted previously shed brucellae from the uterus at subsequent normal parturitions. Organisms are shed in milk for a variable length of time—in most cattle for life. Natural transmission occurs by ingestion of organisms, which are present in large numbers in aborted fetuses, fetal membranes, and uterine discharges. Cattle may ingest contaminated feed and water, or lick contaminated genitals of other animals. Venereal transmission by infected bulls to susceptible cows appears to be rare. Transmission may occur by artificial insemination when Brucella-contaminated semen is deposited in the uterus but, reportedly, not when deposited in the midcervix. Brucellae may enter the body through mucous membranes, conjunctivae, wounds, or even intact skin. Mechanical vectors (eg, other animals, including man) may spread infection. Brucellae have been recovered from fetuses and from manure that has remained in a cool environment for >2 mo. Exposure to direct sunlight kills the organisms within a few hours. Abortion is the most obvious manifestation. Infections may also cause stillborn or weak calves, retained placentas, and reduced milk yield. Usually, general health is not impaired in uncomplicated abortions. Seminal vesicles, ampullae, testicles, and epididymides may be infected in bulls; therefore, organisms are in the semen. Agglutinins may be demonstrated in seminal plasma from infected bulls. Testicular abscesses may occur. Long-standing infections may result in arthritic joints in some cattle.
Clostridia are relatively large, anaerobic, spore-forming, rod-shaped organisms. The spores are oval, sometimes spherical, and are central, subterminal, or terminal in position. The vegetative forms of clostridia in tissue fluids of infected animals occur singly, in pairs, or rarely in chains. Differentiation of the various pathogenic and related species is based on cultural characteristics, spore shape and position, biochemical reactions, and the antigenic specificity of toxins or surface antigens. The natural habitats of the organisms are the soil and intestinal tract of animals, including man. Pathogenic strains may be acquired by susceptible animals either by wound contamination or by ingestion. Diseases thus produced are a constant threat to successful livestock production in many parts of the world.
Clostridium haemolyticum is a soil-borne organism that may be found naturally in the GI tract of cattle. It may survive for long periods in contaminated soil or in bones from carcasses of animals that had been infected. After ingestion, latent spores ultimately become lodged in the liver. The incubation period is extremely variable, and the onset depends on the presence of a locus of anaerobiosis in the liver. Such a nidus for germination is most often caused by fluke infection, much less often by high nitrate content of the diet, accidental liver puncture, liver biopsy, or any other cause of localized necrosis. When conditions for anaerobiosis are favorable, the spores germinate, and the resulting vegetative cells multiply and produce β toxin (phospholipase C), which causes intravascular hemolysis and its sequelae, including hemolytic anemia and hemoglobinuria. Cattle may be found dead without premonitory signs. Usually, there is a sudden onset of severe depression, fever, abdominal pain, dyspnea, dysentery, and hemoglobinuria. Anemia and jaundice are present in varying degrees. Edema of the brisket may occur. Hgb and RBC levels are quite low. The duration of clinical signs varies from ˜12 hr in pregnant cows to ˜3-4 days in other cattle. The mortality in untreated animals is ˜95%. Some cattle suffer from subclinical attacks of the disease and thereafter act as immune carriers. Dehydration, anemia, and sometimes subcutaneous edema are present. There is bloody fluid in the abdominal and thoracic cavities. The lungs are not grossly affected, and the trachea contains bloody froth with hemorrhages in the mucosa. The small intestine and occasionally the large intestine are hemorrhagic; their contents often contain free or clotted blood. An anemic infarct in the liver is virtually pathognomonic; it is slightly elevated, lighter in color than the surrounding tissue, and outlined by a bluish red zone of congestion. The kidneys are dark, friable, and usually studded with petechiae. The bladder contains purplish red urine. After death, rigor mortis sets in more rapidly than usual.
Clostridium chauvoei occurs naturally in the intestinal tract of animals. It probably may remain viable in the soil for many years, although it does not actively grow there. Contaminated pasture appears to be a source of organisms. Outbreaks of blackleg have occurred in cattle on farms in which recent excavations have occurred, which suggests that disturbance of soil may activate latent spores. The organisms probably are ingested, pass through the wall of the GI tract, and after gaining access to the bloodstream, deposited in muscle and other tissues. In cattle, blackleg infection is endogenous, in contrast to malignant edema. Lesions develop without any history of wounds, although bruising or excessive exercise may precipitate some cases. Commonly, the animals that contract blackleg are of the beef breeds, in excellent health, gaining weight, and usually the best animals of their group. Outbreaks occur in which a few new cases are found each day for several days. Most cases occur in cattle from 6 months to 2 years old, but thrifty calves as young as 6 weeks and cattle as old as 10-12 years may be affected. The disease usually occurs in summer and fall and is uncommon during the winter. In sheep, the disease is not restricted to the young, and most cases follow some form of injury such as shearing cuts, docking, crutching, or castration. Usually, onset is sudden and a few cattle may be found dead without premonitory signs. Acute lameness and marked depression are common. Initially, there is a fever but, by the time clinical signs are obvious, the temperature may be normal or subnormal. Characteristic edematous and crepitant swellings develop in the hip, shoulder, chest, back, neck, or elsewhere. At first, the swelling is small, hot, and painful. As the disease rapidly progresses, the swelling enlarges, there is crepitation on palpation, and the skin becomes cold and insensitive as the blood supply to the area diminishes. General signs include prostration and tremors. Death occurs in 12-48 hrs. In some cattle, the lesions are restricted to the myocardium and the diaphragm, with no reliable ante mortem evidence of the localized lesion.
Clostridium novyi has been suspected but not yet confirmed as a cause of sudden death in cattle and pigs fed high-level grain diets, and in which pre-existing lesions of the liver were not detectable. The lethal and necrotizing toxins (primarily a toxin) damage hepatic parenchyma, thereby permitting the bacteria to multiply and produce a lethal amount of toxin. Usually, death is sudden with no well-defined signs. Affected animals tend to lag behind the flock, assume sternal recumbency, and die within a few hours. Most cases occur in the summer and early fall when liver fluke infection is at its height. The disease is most prevalent in 1- to 4-year-old sheep and is limited to animals infected with liver flukes. Differentiation from acute fascioliasis may be difficult, but peracute deaths of animals that show typical lesions on necropsy should arouse suspicion of infectious necrotic hepatitis. The most characteristic lesions are the greyish yellow necrotic foci in the liver that often follow the migratory tracks of the young flukes. Other common findings are an enlarged pericardial sac filled with straw-colored fluid, and excess fluid in the peritoneal and thoracic cavities. Usually, there is extensive rupture of the capillaries in the subcutaneous tissue, which causes the adjacent skin to turn black (hence the common name, black disease).
Clostridium septicum is found in soil and intestinal contents of animals (including man) throughout the world. Infection ordinarily occurs through contamination of wounds containing devitalized tissue, soil, or some other tissue-debilitant. Wounds caused by accident, castration, docking, unsanitary vaccination, and parturition may become infected. General signs, such as anorexia, intoxication, and high fever, as well as local lesions, develop within a few hours to a few days after predisposing injury. The local lesions are soft swellings that pit on pressure and extend rapidly because of the formation of large quantities of exudate that infiltrates the subcutaneous and intramuscular connective tissue of the affected areas. The muscle in such areas is dark brown to black. Accumulations of gas are uncommon. Severe edema of the head of rams occurs after infection of wounds inflicted by fighting. Malignant edema associated with lacerations of the vulva at parturition is characterized by marked edema of the vulva, severe toxemia, and death in 24-48 hours. Similarity to blackleg is marked, and differentiation made on necropsy is unreliable; laboratory confirmation is the only certain procedure. Horses and pigs are susceptible to malignant edema but not to blackleg.
Infectious disease caused by Clostridium sordellii is also manifested as malignant edema in cattle, and also characterized by a nongaseous, nonhemorrhagic, edematous swelling of the head, face, and neck of young rams. This infection is initiated in young rams by their continual butting of one another. The bruised and battered subcutaneous tissues provide conditions suitable for growth of pathogenic clostridia, and the breaks in the skin offer an opportunity for their entrance
Infection with C. perfringens types A, B and C causes severe enteritis, dysentery, toxemia, and high mortality in young calves. Types B and C both produce the highly necrotizing and lethal β toxin that is responsible for the severe intestinal damage. This toxin is sensitive to proteolytic enzymes, and disease is associated with inhibition of proteolysis in the intestine. Sow colostrum, which contains a trypsin inhibitor, has been suggested as a factor in the susceptibility of young piglets. Type C also causes enterotoxemia in adult cattle. In calves, there is acute diarrhea, dysentery, abdominal pain, convulsions, and opisthotonos. Death may occur in a few hours, but less severe cases survive for a few days, and recovery over a period of several days is possible. Hemorrhagic enteritis with ulceration of the mucosa is the major lesion in all species. Grossly, the affected portion of the intestine is deep blue-purple and appears at first glance to be an infarction associated with mesenteric torsion. Smears of intestinal contents may be examined for large numbers of gram-positive, rod-shaped bacteria, and filtrates made for detection of toxin and subsequent identification by neutralization with specific antiserum.
This classic enterotoxemia caused by C. perfringens type D rarely occurs in cattle. It is worldwide in distribution and may occur in animals of any age. The disease has been suspected in well-nourished beef calves nursing high-producing cows grazing lush pasture and in sudden death syndrome in feedlot cattle; however, supportive laboratory evidence in the latter is lacking. Acutely affected calves not found dead show mania, convulsions, blindness, and death in a few hours. Subacutely affected calves are stuporous for a few days and may recover.
Tetanus toxemia is caused by a specific neurotoxin produced by Clostridium tetani in necrotic tissue. Almost all mammals are susceptible to this disease. Although tetanus is worldwide in distribution, there are some areas, such as the northern Rocky Mountain section of the USA, where the organism is rarely found in the soil and where tetanus is almost unknown. In general, the occurrence of C. tetani in the soil and the incidence of tetanus in man and horses is higher in the warmer parts of the various continents. Clostridium tetani, an anaerobe with terminal, spherical spores, is found in soil and intestinal tracts. In most cases, it is introduced into the tissues through wounds, particularly deep puncture wounds, which provide a suitable anaerobic environment.
Infection with Salmonella spp may produce diarrhea in animals of all ages, especially those that are stressed, closely stocked, or exposed to a heavily contaminated feed or water supply. Salmonellosis is caused by many species of salmonellae and characterized clinically by one or more of three major syndromes—septicemia, acute enteritis, and chronic enteritis. The incidence has increased with the intensification of livestock production. Young calves usually develop the septicemic form. Adult cattle develop acute enteritis. Chronic enteritis may develop occasionally in cattle. Pregnant animals may abort. In older animals, the disease is manifested by dysentery and toxemia, and mortality may be significant. While many other Salmonella spp may cause disease, the more relevant in cattle are S. typhimurium, S. dublin, and S. newport. Although their resulting clinical patterns are not distinct, different species of salmonellae tend to differ in their epidemiology. Plasmid profile and drug-resistance patterns are sometimes useful markers for epidemiologic studies. Feces of infected animals may contaminate feed and water, milk, fresh and processed meats from abattoirs, plant and animal products used as fertilizers or feedstuffs, pasture and rangeland, and many inert materials. The organisms may survive for months in wet, warm areas such as in feeder pig barns or in water dugouts but survive less than 1 week in composted cattle manure. Rodents and wild birds also are sources of infection. The prevalence of infection varies among species and countries and is much higher than the incidence of clinical disease, which is commonly precipitated by stressful situations such as sudden deprivation of feed, transportation, drought, crowding, parturition, and the administration of some drugs.
Further relevant gastro-intestinal pathogens that may be used in the present invention include Escherichia coli, Cryptosporidium parvum and Mycobacterium avium paratuberculosis. Escherichia coli infection causes severe intestinal disease in young animals characterized as neonatal diarrhea, post weaning diarrhea, edema disease, and/or septicemia depending upon the virulence factors present in the strain causing the infection. Calves infected with pathogenic E. coli may develop severe diarrhea causing fatal dehydration, or fatal septicemic infections. Paratuberculosis is a chronic contagious enteritis characterized by persistent and progressive diarrhea, weight loss, debilitation, and eventually death. It affects cattle, sheep, goats, llamas, camels, farmed deer, and other domestic, exotic, and wild ruminants. It has also been recognized in wild rabbits; horses and pigs may be infected experimentally. Distribution is worldwide.
Animals with paratuberculosis should be considered as potential zoonotic risks until the situation is clarified. The causative organism is Mycobacterium avium paratuberculosis, formerly known as M. paratuberculosis or M. johnei. Occasionally, other M. avium subspecies are isolated from cases. The organism is quite resistant and may survive on pasture for more than 1 year, but sunlight, alkaline soils, and drying reduce its survival rate. It is shed in large numbers in feces of infected animals, and infection is acquired by ingestion of contaminated feed and water. Introduction of the disease into a clean herd is usually by subclinically infected carriers. Infection is acquired early in life, but clinical signs rarely develop in cattle <2 years old. Resistance increases with age, and cattle first exposed as adults are unlikely to become infected. Most calves are infected soon after birth either by nursing udders contaminated with feces from infected animals or by being housed in contaminated pens. The organism may also be present in colostrum and milk of infected cows, and intrauterine infections have also been described. After ingestion, the bacteria infect macrophages in the mucosa of the lower small intestine and in associated lymph nodes. Most animals will eliminate infection by an early cell-mediated immune response that encourages microbicidal activity in macrophages. In susceptible animals, the organisms multiply and provoke a chronic enteritis that leads to clinical disease. This may take months to years to develop and is usually paralleled by a decline in cell-mediated immunity and a rise in ineffective serum antibody. However, fecal shedding begins before clinical signs are apparent. Mycobacterium avium paratuberculosis may be isolated from feces, mesenteric and ileocecal lymph nodes, thickened intestinal walls, and less frequently the udder and the reproductive tracts of both sexes.
Cryptosporidiosis is an enterocolitis of cosmopolitan distribution caused by the coccidian parasite Cryptosporidium parvum. It is not host-specific and is common in young ruminants, particularly calves; it is also found in man and pigs and is rare in dogs, cats, and horses. Other cryptosporidia cause disease in reptiles and birds. The disease in calves, characterized by weight loss and watery diarrhea, is clinically indistinguishable from many other causes of calf diarrhea. Cryptosporidium parvum is a minute protozoan that is transmitted by the fecal-oral route. Oocysts are sporulated (four sporozoites) when shed in the feces and, therefore, are immediately infective. The mean incubation period is ˜4 days. Calves 1-3 weeks old seem to be most susceptible. Signs such as anorexia, weight loss, diarrhea, and tenesmus, resemble those caused by several other intestinal pathogens; however, infections without signs do occur. Uncomplicated cryptosporidiosis is seldom fatal. Disease may be severe in immuno-compromised individuals. If severe disease in calves is seen, other disease agents or concurrent infections should be ruled out. Although C. parvum may infect virtually the entire intestinal tract, the distal small intestine usually is affected most severely. Infection in horses is limited to the small intestine. Gross lesions may consist of hyperemic intestinal mucosa and yellowish intestinal contents. Microscopically, mild to severe villous atrophy with spherical organisms in the brush border is evident. Unlike Eimeria and Isospora spp, which are intracellular parasites, C. parvum is intramembranous and resides within the brush border of the intestinal epithelial cells.
Inflammation of the mammary gland (mastitis) is almost always due to the effects of infection by bacterial or mycotic pathogens. Mastitis may be associated with infection by many other organisms, including Streptococcus uberis, Streptococcus dysgalactiae, Streptococcus agalactiae, Staphylococcus aureus, Escherichia coli, Klebsiella spp. Pseudomonas aeruginosa, Actinomyces pyogenes, Mycoplasma spp, Nocardia asteroides, Serratia, Mycobacterium spp, Clostridium perfringens, Pasteurella spp, yeasts, and Prototheca spp.
Dermatomycoses (Dermatophytosis) in animals are anthropozoonotic diseases of the skin and related tissue. Clinical symptoms are characterized by loss of hair in the affected area, hyperemia, scaling and asbestos-like scabs. Inflammation is often accompanied by suppuration. Dermatomycoses are often also characterized by localized infection of the skin. Dermatomycoses in animals carry a substantial socioeconomic impact. Diseased animals required prolonged treatment and may spread infection to both animals and humans. Dermatophytosis are caused by mycosis infections of Trichophyton spp. or Microsporum spp. Most relevant causes for cattle are Trichophyton verrucosum, Trichophyton mentagrophytes or Trichophyton sarkisovii.
An infection of the lower respiratory tract, usually resulting in bronchitis or pneumonia, may be caused by any of several parasitic nematodes, including Dictyocaulus viviparus in cattle. This lungworm belongs to the superfamily Trichostrongyloidea and has direct life cycles. The cattle lungworm is common in northwest Europe and is the cause of severe outbreaks of “husk” or “hoose” in young grazing cattle. Because D. viviparus infection in cattle is the most economically important, it has been most investigated and many of the observations from it are applicable to the other species. Clinical disease usually develops on first exposure to sufficient infective larvae. In cattle, this usually occurs during their first season at pasture; however, an increase in the number of older cattle affected has been reported. Signs of lungworm infection range from moderate coughing with slightly increased respiratory rates to severe persistent coughing and respiratory distress and even failure. Reduced weight-gains, reduced milk yields, and weight loss accompany many infections in cattle. Patent subclinical infections may occur in all species. The most consistent signs in cattle are tachypnea and coughing.
Trichomoniasis is a venereal protozoal disease of cattle characterized primarily by early fetal death and infertility, resulting in extended calving intervals. Distribution is probably worldwide. The causative protozoan, Trichomonas (Tritrichomonas) foetus, is pyriform and ordinarily 10-15×5-10 μm, but there is considerable pleomorphism. It may become spherical when cultured in artificial media. At its anterior end, there are three flagella about the same length as the body of the parasite. An undulating membrane extends the length of the body and is bordered by a marginal filament that continues beyond the membrane as a posterior flagellum. Although T. foetus may survive the process used for freezing semen, it is killed by drying or high temperatures. Trichomonas foetus is found in the genital tracts of cattle. When cows are bred naturally by an infected bull, 30-90% become infected, suggesting that strain differences exist. Variation in breed susceptibility to trichomoniasis may also exist. Bulls of all ages may remain infected indefinitely but this is less likely in younger males. By contrast, most cows are free of infection within 3 months after breeding. However, immunity is not long lasting and reinfection does occur. Transmission may also occur when the semen from infected bulls is used for artificial insemination. The most common sign is infertility caused by embryonic death. This results in repeat breeding and a prolonged calving season. Fetal death and abortions may also occur but are not as common as losses earlier in gestation. Trichomonas foetus has been found in vaginal cultures taken as late as 8 months of gestation and, apparently, live calves may be born to infected dams. Pyometra occasionally develops after breeding.
Neospora caninum is an obligate intracellular protozoan parasite that has been confused previously with Toxoplasma gondii. Only asexual stages are known, and they resemble T. gondii. The complete life cycle of N. caninum is unknown, but it may be transmitted transplacentally in dogs, cattle, goats, sheep, and cats, and subsequent offspring may be affected. Tachyzoites are 5-7×1-5 μm, depending on the stage of division. They divide by endodyogeny. Tachyzoites are found in myocytes, neural cells, dermal cells, macrophages, and other cells. Tissue cysts up to 100 μm in diameter are found in neural cells; the cyst wall is amorphous and up to 4 μm thick. Cysts have no septa and enclose slender 7×1.5 μm bradyzoites. In dairy cattle, N. caninum is a major cause of abortion in many countries, particularly in the USA. Calves may be aborted, stillborn, born underweight, weak, or paralyzed, or they may become paralyzed within 4 weeks of birth. Non-suppurative encephalitis is the main lesion in aborted fetal tissues. Abortion may occur throughout gestation, and some cows may abort again; dams of these calves are clinically normal.
Babesiosis is caused by intraerythrocytic protozoan parasites of the genus Babesia. A wide range of domestic and wild animals and occasionally man is affected by the disease, which is transmitted by ticks and has a worldwide distribution. Two important species in cattle—Babesia bigemina and Babesia bovis—are widespread in tropical and subtropical areas and are the focus of this discussion. In endemic areas, two features are important in determining the risk of clinical disease: 1) calves have a degree of immunity (related both to colostral-derived antibodies and to age) that persists for ˜6 months, and 2) animals that recover from Babesia infections are immune for life. Thus, at high levels of tick transmission, all newborn calves will become infected with Babesia by 6 mos. of age, show few if any clinical signs, and subsequently be immune. This situation of endemic stability may be upset by either a natural (eg, climatic) or artificial (eg, acaricide treatment) reduction in tick numbers to levels where tick transmission of Babesia to calves is insufficient to ensure all are infected during this critical early period. Other circumstances that may lead to clinical outbreaks include the introduction of susceptible cattle to endemic areas and the incursion of Babesia-infected ticks into previously tick-free areas. Strain variation in immunity has been demonstrated but is probably not of significance in the field. The acute disease generally runs a course of ˜1 week. The first sign is fever (frequently 41° C. or higher), which persists throughout, and is accompanied later by inappetence, increased respiratory rate, muscle tremors, anemia, jaundice, and loss of weight with hemoglobinemia and hemoglobinuria in the final stages. CNS involvement due to sludging of parasitized erythrocytes in brain capillaries occurs frequently with B. bovis infection. Either constipation or diarrhea may be present. Pregnant cows often abort. With virulent strains of B. bovis, a hypotensive shock syndrome, combined with generalized non-specific inflammation, coagulation disturbances, and erythrocytic stasis in capillaries, contribute to the pathogenesis. With most strains of B. bigemina, the pathogenic effects relate more directly to erythrocyte destruction. Animals that recover from the acute disease remain infected for a number of years with B. bovis and for a few months in the case of B. bigemina. No signs are apparent during this carrier state. Lesions include an enlarged and friable spleen; a swollen liver with an enlarged gallbladder containing thick granular bile; congested, dark-colored kidneys; and generalized anemia and jaundice. The urine is often, but not invariably, red. Other organs, including the brain and heart, may show congestion or petechial hemorrhages. The susceptibility of cattle breeds to Babesia infections varies; for example, Brahman cattle are more resistant to B. bovis infection than are British breeds.

Dose and Administration
According to the present invention, an effective amount of a combination vaccine administered to cattle provides effective immunity against microbiological infections caused by M. bovis and at least one further pathogen as listed above. Preferred combinations of antigens for the treatment and prophylaxis of microbiological diseases in cattle are listed above.
In preferred forms, the dose volume of the combination vaccine as well as of each immunogenic composition when separately co-administered is no more than 5 ml, more preferably no more than 3 ml, and more preferably no more than 2 ml. In a most preferred embodiment, the dose is 2 ml, preferably administered intranasally, with 1 ml being administered in each nostril, more preferably administered intramuscularly, even more preferably administered subcutaneously, and most preferably administered both intranasally and subcutaneously on one occasion as a single dose. In some preferred forms, a second or subsequent administration of the immunogenic composition would be administered after the first administration. Such a subsequent administration would preferably occur at least 10 days after the initial administration, more preferably between at least 10-32 days, more preferably between at least 12-30 days, still more preferably at least 14 days, and most preferably between at least 14-28 days. In most preferred forms, the vaccine would be administered either as a single dose, preferably on Day 0 or, in alternative forms, 14-28 days thereafter, preferably on Day 0 and 14-28 days thereafter with exposure to pathogenic forms of M. bovis not occurring until after the completion of the immunizing regimen. In a most preferred form, no booster is necessary and the vaccine is administered only one time. The vaccine is administered to animals from 1 day of age through adulthood, preferably to calves from 1 day of age through young adult cattle 2 years of age, more preferably to calves from 1 day of age through 16 weeks of age, and most preferably to calves from 6 weeks to 12 weeks of age. Such administration lessened or reduced signs of M. bovis infection as described below. Preferably, signs of M. bovis infection in the group vaccinated as described above are reduced by at least 50%, more preferably at least 60%, even more preferably at least 70%, and even more preferably at least 75% in comparison to the non-vaccinated group. Lung pathology assessment, specifically the percentage of lung consolidation attributed to lesions due to M. bovis, as customarily scored for various species, was made post-necropsy. Preferably lung lesions are reduced by at least 33%, more preferably at least 50%, even more preferably at least 70%, even more preferably at least 80%, even more preferably at least 90%, and most preferably by at least 95% in comparison to a non-vaccinated group.
The amount of combination vaccine that is effective depends on the ingredients of the vaccine and the schedule of administration. Typically, when bacterial antigen is used in the combination vaccine or in a combined use, the vaccine or immunogenic composition contains an amount of about 103 to about 1010 colony forming units (CFU) of the bacterial antigen per dose, preferably, about 104 to about 109 CFU of the bacterial antigen per dose, more preferably about 105 to about 106 CFU of the bacterial antigen per dose. For instance, the attenuated, avirulent M. bovis is preferably used in amounts of about 102 to about 1010 CFU per dose, preferably about 103 to about 109 CFU per dose, even more preferably in an amount of about 108 to about 1010 CFU per dose, most preferably in an amount of about 2.1×109 CFU per dose.
Typically, when an inactivated virus or a modified live virus preparation is used in the combination vaccine or in a combined use, the vaccine or immunogenic composition containing about 102 to about 109 TCID50 viral antigen per dose, preferably about 103 to about 108 TCID50 viral antigen per dose, more preferably, about 104 to about 108 TCID50 viral antigen per dose. For example, about 105 to about 108 TCID50 per dose of attenuated BVDV (types 1 and 2) is effective when administered twice to the animal during a period of about 3 to 4 weeks. In general, inactivated antigen is normally used in higher amounts than live modified viruses.
In the event the combination vaccine comprises live modified IBR, the amount of IBR antigen is preferably in a range of about 105 to 107.5 TCID50 per dose. In the event the combination vaccine comprises live modified PI3, the amount of PI3 antigen is preferably in a range of about 107 to 109 TCID50 per dose. In the event the combination vaccine comprises live modified BRSV, the amount of BRSV antigen is preferably in a range of about 104.5 to 106.5 TCID50 per dose. In the event the combination vaccine comprises killed antigens the TCID50 or CFU indicates the amount of antigen per dose in the live culture before inactivation, and for IBR, the amount of IBR antigen is preferably in a range of about 107.0 to 109.0 TCID50 per dose. In the event the combination vaccine comprises killed PI3, the amount of PI3 antigen is preferably in a range of about 107.2 to 109.2 TCID50 per dose. In the event the combination vaccine comprises killed BRSV, the amount of BRSV antigen is preferably in a range of about 105.0 to 107.5 TCID50 per dose. In the event the combination vaccine comprises killed Leptospira spp. the amount of each Leptospira spp. antigen is preferably in a range of about 107.0 to 1010 (CFU) per dose. In the event the combination vaccine comprises killed H. somnus, and/or killed Pasteurella multocida, and/or killed Mannheimia haemolytica the amount of H. somnus antigen and/or Pasteurella multocida antigen, and/or Mannheimia haemolytica antigen is preferably in a range of about 106.0 to 1010 colony forming unit (CFU) per dose.

Preferably, the further immunogenic composition comprises one or more immunologically active component(s) effective for the treatment and/or prophylaxis of infections caused by a pathogen of cattle other than M. bovis. More preferably, the first and the further immunogenic compositions are administered together by means such as mixing before administration and/or by formulating the first and the further immunogenic compositions in a single container.
The co-administration of each of the immunogenic compositions occurs simultaneously, which means at least within 48 hours, preferably within 24 hours, even more preferably within 12 hours, even more preferably within 6 hours, even more preferably within 3 hours, even more preferably within 2, hours, even more preferably within 1 hour. The route of administration of each of the immunogenic compositions depends on the mode-of-action and may be the same, but also could be different.
According to a further embodiment the M. bovis antigen as provided herewith and one or more further immunologically active component(s) effective for the treatment and/or prophylaxis of infections caused by a further cattle relevant pathogen other than M. bovis can be used a medicament. Preferably, that medicament is a vaccine and can be used for lessening or reducing the signs of a M. bovis infection. Most preferably, that medicament or vaccine can be used for lessening or reducing the signs of a M. bovis infection and associated with or caused by an infection of the further cattle relevant antigen.
Formulations
A further aspect of the present invention is the preparation of the combination vaccine(s). One of skill in the art can determine additional components which are present in the composition of the invention. (see also Remington's Pharmaceutical Sciences, (1990) 18th ed. Mack Publ., Easton). Known injectable, physiologically acceptable sterile solutions may be used. For preparing a ready-to-use solution for parenteral injection or infusion, aqueous isotonic solutions, such as e.g. saline or corresponding plasma protein solutions, are readily available. The pharmaceutical compositions of the present invention may be present as lyophylisates or dry preparations, which can be reconstituted with a known injectable solution directly before use under sterile conditions, e.g. as a kit of parts.
In addition, the immunogenic and vaccine compositions of the present invention can include one or more veterinary-acceptable carriers. As used herein, “a veterinary-acceptable carrier” includes any and all solvents, dispersion media, coatings, adjuvants, stabilizing agents, diluents, preservatives, antibacterial and antifungal agents, isotonic agents, adsorption delaying agents, and the like.
Diluents can include water, saline, dextrose, ethanol, glycerol, and the like. Isotonic agents can include sodium chloride, dextrose, mannitol, sorbitol, and lactose, among others. Stabilizers include albumin and alkali salts of ethylendiamintetracetic acid, among others.
Adjuvants include, but are not limited to, the RIBI adjuvant system (Ribi Inc.), alum, aluminum hydroxide gel, Cholesterol, oil-in water emulsions, water-in-oil emulsions such as, e.g., Freund's complete and incomplete adjuvants, Block co-polymer (CytRx, Atlanta Ga.), SAF-M (Chiron, Emeryville Calif.), CARBOPOL®, AMPHIGENO adjuvant, saponin, Quil A, QS-21 (Cambridge Biotech Inc., Cambridge Mass.), GPI-0100 (Galenica Pharmaceuticals, Inc., Birmingham, Ala.) or other saponin fractions, monophosphoryl lipid A, Avridine lipid-amine adjuvant, heat-labile enterotoxin from E. coli (recombinant or otherwise), cholera toxin, or muramyl dipeptide, among many others.
The immunogenic compositions can further include one or more other immunomodulatory agents such as, e.g., interleukins, interferons, or other cytokines. The immunogenic compositions can also include Gentamicin and Merthiolate. While the amounts and concentrations of adjuvants and additives useful in the context of the present invention can readily be determined by the skilled artisan, preferably the composition comprises from about 50 ug to about 2000 ug of adjuvant and preferably about 250 ug/ml dose of the vaccine composition. In another preferred embodiment, the present invention an antibiotic is present in an amount of from about 1 ug/ml to about 60 ug/ml of and preferably less than about 30 ug/ml. According to a further embodiment the combination vaccine (or immunogenic composition) is first dehydrated. If the composition is first lyophilized or dehydrated by other methods, then, prior to vaccination, said composition is rehydrated in aqueous (e.g. saline, PBS (phosphate buffered saline)) or non-aqueous solutions (e.g. oil emulsion (mineral oil, or vegetable/metabolizable oil based/single or double emulsion based), aluminum-based, carbomer based adjuvant).
According to a further embodiment, the immunogenic composition or combination vaccine as provided herewith, which comprises at least one M. bovis antigen and one or more further immunologically active component(s) effective for the treatment and/or prophylaxis of infections caused by a further cattle relevant pathogen other than M. bovis are formulated as fix-dose combination vaccine. Preferably, the immunogenic composition or combination vaccine provided herewith, in particular the fix-dose combination vaccine is formulated for use as a single-dose or multi-dose vaccine, whereas the formulation for use as a single-dose vaccine is most preferred. In other words the immunogenic compositions or vaccine, preferably the fix-dose combination vaccine provided herewith is formulated for the administration as a multi-dose or single-dose, whereas the formulation for the administration as single-dose is most preferred. As shown in the example section, such a single dose administration of the M. bovis antigen is effective in lessening or reducing the signs of an M. bovis infection. Thus, according to a further embodiment, the immunogenic compositions provided herewith, in particular the fix-dose combination vaccine is formulated for use as a single-dose vaccine, wherein the administration of such single-dose is effective in lessening or reducing the signs of an M. bovis infection.
Modes of Administration and Dosing
Compositions of the present invention may be administered in any conventional manner. Examples of administration methods include any that afford access by cells of the immune system to the immunogenic composition, including but not limited to, oral, transdermal, intradermal, intravenous, subcutaneous, intramuscular, intraocular, intraperitoneal, intrarectal, intravaginal, intranasal, intragastrical, intratracheal, intrapulmonarial, or any combination thereof. Preferred modes of administration are intramuscular, subcutaneous and intranasal, with subcutaneous and intranasal being especially preferred. If desired or necessary, booster immunizations may be given once or several times at various intervals. However, it is a preferred embodiment of the present invention that the vaccination be administered as a single-dose. After administration of such a vaccine, an immune response is elicited in the animal and signs of M. bovis infection are reduced in incidence and/or severity, as well as a reduction in rate of mortality, in comparison to animals exposed to wild-type bacteria or isolates after challenge with a virulent form of M. bovis.
In preferred forms, the dose volume of the vaccine is no more than 5 ml, more preferably no more than 3 ml, and more preferably no more than 2 ml. In a most preferred embodiment, the dose would be 2 ml, preferably administered intranasally, with 1 ml being administered in each nostril, even more preferably administered subcutaneously, and most preferably administered both intranasally and subcutaneously on one occasion as a single dose. In some preferred forms, a second or subsequent administration of the immunogenic composition would be administered after the first administration.
Such a subsequent administration would preferably occur at least 10 days after the initial administration, more preferably between at least 10-32 days, more preferably between at least 12-30 days, still more preferably at least 14 days, and most preferably between at least 14-28 days. In most preferred forms, the vaccine would be administered either on Day 0 as a single dose, or, in alternative forms, on Day 0 and 14-28 days thereafter with exposure to pathogenic forms of M. bovis not occurring until after the completion of the immunizing regimen. In a most preferred form, no booster is necessary and the vaccine is administered only one time. The vaccine is administered to animals from 1 day of age through adulthood, preferably to calves from 1 day of age through young adult cattle 2 years of age, more preferably to calves from 1 day of age through 16 weeks of age, and most preferably to calves from 6 weeks to 12 weeks of age. Such administration reduced signs of M. bovis infection as described below. In fact, the studies herein show that signs of M. bovis infection in the group vaccinated as described above were reduced by at least 50%, more preferably, at least 60%, even more preferably, at least 70%, even more preferably, at least 75%, more preferably, at least 80%, still more preferably at least 83%, more preferably, at least 85%, and, most preferably, at least 90% in comparison to the non-vaccinated group.
In a preferred embodiment, the immunogenic compositions of the present invention are effective in stimulating an onset of immunity within 14 days following a single dose administration. In an additionally preferred embodiment the immunogenic composition of the present invention is effective in stimulating duration of immunity of at least 42 days following a single dose administration of the immunogenic composition.
In another preferred embodiment, the immunogenic compositions of the present invention may be co-administered to an animal (preferably cattle). Specifically two or more antigens may be administered to an animal of the M. bovis antigen of the present invention and at least one other immunologically active component(s) effective for the treatment and/or prophylaxis of infections caused by a further cattle relevant pathogen other than M. bovis (discussed in more detail infra). The M. bovis antigen of the present invention and the immunologically active component(s) may be co-administered or administered separately. An example of separate co-administration includes the M. bovis antigen and the immunologically active component(s) occurring within 2 days. Alternatively, the M. bovis antigen and one or more immunologically active component(s) may be formulated as fix-dose combination vaccine. Another preferred embodiment would be administering the two or more antigens which comprise M. bovis antigen and one or more immunologically active component(s) effective for the treatment and/or prophylaxis of infections caused by a further cattle relevant pathogen other than M. bovis are in one only dose. Alternatively two, three, or four doses may be administered that is, co-administered or administered separately.
In a preferred embodiment, the immunogenic composition of the present invention contains an adjuvant. Adjuvants may include aluminum hydroxide and aluminum phosphate, saponins e.g., Quil A, QS-21 (Cambridge Biotech Inc., Cambridge Mass.), GPI-0100 (Galenica Pharmaceuticals, Inc., Birmingham, Ala.), water-in-oil emulsion, oil-in-water emulsion, water-in-oil-in-water emulsion. The emulsion may be based in particular on light liquid paraffin oil (European Pharmacopea type); isoprenoid oil such as squalane or squalene; oil resulting from the oligomerization of alkenes, in particular of isobutene or decene; esters of acids or of alcohols containing a linear alkyl group, more particularly plant oils, ethyl oleate, propylene glycol di-(caprylate/caprate), glyceryl tri-(caprylate/caprate) or propylene glycol dioleate; esters of branched fatty acids or alcohols, in particular isostearic acid esters. The oil is used in combination with emulsifiers to form the emulsion. The emulsifiers are preferably nonionic surfactants, in particular esters of sorbitan, of mannide (e.g. anhydromannitol oleate), of glycol, of polyglycerol, of propylene glycol and of oleic, isostearic, ricinoleic or hydroxystearic acid, which are optionally ethoxylated, and polyoxypropylene-polyoxyethylene copolymer blocks, in particular the Pluronic products, especially L121. See Hunter et al., The Theory and Practical Application of Adjuvants (Ed. Stewart-Tull, D. E. S.). John Wiley and Sons, NY, pp 51-94 (1995) and Todd et al., Vaccine 15:564-570 (1997), hereby entirely incorporated by reference. For example, it is possible to use the SPT emulsion described on page 147 of “Vaccine Design, The Subunit and Adjuvant Approach” edited by M. Powell and M. Newman, Plenum Press, 1995, and the emulsion MF59 described on page 183 of this same book.
A further instance of an adjuvant is a compound chosen from the polymers of acrylic or methacrylic acid and the copolymers of maleic anhydride and alkenyl derivative. Advantageous adjuvant compounds are the polymers of acrylic or methacrylic acid which are cross-linked, especially with polyalkenyl ethers of sugars or polyalcohols. These compounds are known by the term carbomer (Phameuropa Vol. 8, No. 2, June 1996, hereby entirely incorporated by reference). Persons skilled in the art may also refer to U.S. Pat. No. 2,909,462 (hereby entirely incorporated by reference) which describes such acrylic polymers cross-linked with a polyhydroxylated compound having at least 3 hydroxyl groups, preferably not more than 8, the hydrogen atoms of at least three hydroxyls being replaced by unsaturated aliphatic radicals having at least 2 carbon atoms. The preferred radicals are those containing from 2 to 4 carbon atoms, e.g. vinyls, allyls and other ethylenically unsaturated groups. The unsaturated radicals may themselves contain other substituents, such as methyl. The products sold under the name Carbopol (BF Goodrich, Ohio, USA) are particularly appropriate. They are cross-linked with an allyl sucrose or with allyl pentaerythritol. Among then, there may be mentioned Carbopol 974P, 934P and 971P. Most preferred is the use of Cabopol 971P. Among the copolymers of maleic anhydride and alkenyl derivative, are the copolymers EMA (Monsanto), which are copolymers of maleic anhydride and ethylene. The dissolution of these polymers in water leads to an acid solution that will be neutralized, preferably to physiological pH, in order to give the adjuvant solution into which the immunogenic, immunological or vaccine composition itself will be incorporated.
Further suitable adjuvants include, but are not limited to, the RIBI adjuvant system (Ribi Inc.), Block co-polymer (CytRx, Atlanta Ga.), SAF-M (Chiron, Emeryville Calif.), monophosphoryl lipid A, Avridine lipid-amine adjuvant, heat-labile enterotoxin from E. coli (recombinant or otherwise), cholera toxin, IMS 1314 or muramyl dipeptide, or naturally occurring or recombinant cytokines or analogs thereof or stimulants of endogenous cytokine release, among many others.
Preferably, the adjuvant is added in an amount of about 100 μg to about 1 g per dose. Even more preferably the adjuvant is added in an amount of about 100 μg to about 500 mg per dose. Even more preferably the adjuvant is added in an amount of about 500 μg to about 250 mg per dose. Even more preferably the adjuvant is added in an amount of about 750 μg to about 100 mg per dose. Even more preferably the adjuvant is added in an amount of about 1 mg to about 50 mg per dose. Even more preferably the adjuvant is added in an amount of about 1 mg to about 10 mg per dose. Most preferably the adjuvant is added in an amount of about 1 mg per dose.
Carriers
In addition, the immunogenic and vaccine compositions of the present invention may include one or more veterinary-acceptable carriers. Thus, the present invention relates to the use of an M. bovis strain, attenuated through multiple passage or serial attenuation as described above, as a medicine, preferably as a veterinary medicine. M. bovis strains attenuated as described above may be used for the preparation of a pharmaceutical composition, as described herein, for the prophylaxis or treatment of infections caused by M. bovis. As noted above, those pharmaceutical compositions/vaccine compositions may be used for the treatment and/or prophylaxis of animals susceptible to infection by M. bovis.
Methods of Treatment or Prophylaxis
In another aspect of the present invention, the invention is a method for the treatment or prophylaxis including a lessening of the incidence of wild type infection in a herd or reduction in the severity of signs of M. bovis infection associated with wild type M. bovis infected animals administered immunogenic compositions in accordance with the present invention in comparison to animals that are either not vaccinated or vaccinated with vaccines available prior to the present invention is provided. Additionally, administration of the vaccine in accordance with the present invention reduces the number of animals in a herd that become infected with M. bovis. Such a method generally involves the administration of a therapeutically effective amount of an M. bovis strain attenuated through the methods disclosed above, to a subject or herd of subjects in need of such a treatment. Preferably, clinical symptoms are lessened in incidence or severity by at least 10%, more preferably by at least 20%, still more preferably by at least 30%, even more preferably by at least 40%, still more preferably by at least 50%, even more preferably by at least 60%, still more preferably by at least 70%, even more preferably by at least 80%, still more preferably by at least 90%, and most preferably by at least 95% in comparison to animals that are either not vaccinated or vaccinated with an M. bovis immunogenic composition that was available prior to the present invention but subsequently infected by wild-type M. bovis.
The following examples are provided for the purposes of illustration and are not intended to limit the scope of the present invention
Materials and Methods
Forty-four (44) calves were reared. Post-weaning, the calves were randomly assigned to 1 of 5 groups. Calves were 6±2 weeks of age at initiation of the study and received vaccination according to group assignment on Day 0 and Day 14. Approximately four (4) weeks later (Day 27), calves were challenged with virulent M. bovis or media only according to group assignment. Sixteen (16) days after challenge, (Day 43) the calves were necropsied. The group treatments are summarized in Table 1.

Sampling
Swab
Nasal swabs were collected from all calves on Days −22, 0, 14, 27, 34 and 43 (or day of post). At necropsy, tonsil swabs were collected from all calves. Joint swabs were taken from animals with clinical abnormalities. In addition, samples were taken from other locations in certain animals showing area involvement. In all cases, three sterile swabs were rubbed around the regions, as aseptically as possible, for a few seconds and then removed. The swabs were placed back into the transport containers. Two swabs were placed into individual transport containers with media and one was placed into a transport container without media. The swabs were appropriately labeled with the Study number, calf ID number and date. Sample collections were recorded on the Sample Collection Record. The swabs were stored on ice and transported the same day to BIVI—St. Joseph. The deliveries of the swabs were documented on a Specimen
Delivery Form
Sera
Blood was collected from all calves on Days −42, 0, 14, 27, 34 and 43 (or day of post). Blood was collected aseptically from a jugular vein from each calf into one 12.5 mL Serum Separator Tube (SST). Sample collections were recorded on the Sample Collection Record. The blood was delivered to BIVI—St. Joseph with the delivery being documented on a Specimen Delivery Form. Serum was then harvested from each tube by centrifugation and transferred to a sterile cryovial. The samples were stored at 4° C. until testing followed by long term storage at −20° C.
Tissue
From all animals, samples of lung were collected at the discretion of the Study Investigator. Areas in which gross lesions were observed were targeted for sampling. Samples were placed in whirl pack bags and labeled with the animal number. The tissue samples were stored on ice and transported the same day to BIVI—St. Joseph. An additional set of lung tissues were collected and placed into 10% formalin solution and appropriately labeled. Fixed tissue samples were shipped to ISU—Veterinary Diagnostic Laboratory. The sample sites selected for each calf are listed on the Sample Collection Record.
Testing
Microbiology
Swabs placed in the transport media and tissue samples were shipped to BIVI for Mycoplasma bovis isolation (day of posting samples only). Briefly, swabs were swirled in 5 mL Mycoplasma selective broth. A small sample (approx. 5 mm) was cut from lung tissue and homogenized in 5 mL of complete Friis media. 100 ul of homogenate were added to Mycoplasma selective broth. Cultures were incubated at 37C/5% CO2. After 4-14 days, the broth was examined for growth and subcultured to plates for isolation. All positive subculture samples were stored at −70° C.
PCR
Swabs from each calf not placed in transport media and tissue samples were shipped to BIVI where DNA was extracted and tested by PCR using primers and probe specific for the uvrC gene of M. bovis developed at BIVI. Results of PCR were expressed as positive or negative for M. bovis DNA detection.
Serology
Serum samples were tested using an ELISA commercially available by Biovet (Canada) using the protocol provided with the test kit. ELISA results are expressed as Optical Density (OD) readings. Sample OD's were compared to the Positivity level (Mean ODp×0.3) established by the positive control included in the test kit. Positive results were then interpreted according to the manufacturer's classification scheme. 0 being no seroconversion to 4 being very strong seroconversion (see seroconversion below in Table 3).
Histopathology/IHC
Formalin-fixed tissues were sent to ISU Veterinary Diagnostic laboratory and tested by hematoxylin/eosin stained slide and immunohistochemistry using monoclonal antibodies specific for M. bovis
Clinicals
Daily general observations were carried out from Day 0 to Day 27 and then daily clinical observations made from Day 28 to euthanasia and necropsy. Clinical and general observations noted deviation from the norm and were documented.
Necropsy
Following euthanasia, each animal was necropsied. The thoracic cavity and trachea were examined for each calf and gross observations recorded on the Necropsy Report Record. The lungs and about 6 inches of trachea from each calf were removed intact for further examination and sample collection.
Lung Pathology
For each set of lungs, each lung lobe was examined by visualization and by palpation. The quality and amount of pathology present (as a percent) per each lung lobe due to M. bovis was determined. Each lung lobe percent was then weighted and summed to determine the percentage of total lung with pathology.
Joint Pathology
Affected joints were examined and gross observations recorded.
Discussion
The objective of this study was to evaluate the efficacy of a live high passage M. bovis vaccine candidate at 3 different dosage levels (1E9, 1E8 and 1E7 CFU per dose) administered subcutaneously (SQ) with a single dose (Day 0). A vaccine control group was also included and given two doses (days 0 and 14) SQ and intranasally (IN) with the high dose level of vaccine.
The challenge and vaccine candidate Mycoplasma bovis isolates used in this study originated from different naturally infected farms. The challenge isolate was previously shown to cause both lung and joint disease during experimental challenge and predominated in mixed isolate challenge studies. The live vaccine candidates are high passage isolates originally derived from diagnostic samples. High passage of the vaccine candidates was performed by serial limiting dilution in Friis base media supplemented with horse serum and yeast extract. Although no appreciable difference has been observed in the growth rate in the Friis complete media, at high passage, vaccine candidate PTA-9666 has demonstrated restricted growth on some Mycoplasma selective agar formulations while the low passage parent isolate shows no apparent growth restriction. Also, genotypes of the challenge and vaccine isolates are dissimilar (as determined by insertion sequence PCR fingerprinting).
The challenge procedure using a total volume of 30 mL of the challenge isolate and resulted in the challenge control group showing lung pathology in all animals and joint involvement in 6 of 8 animals.
Multiple parameters were investigated during this study to access vaccine benefits and identify possible primary parameters for future studies. Of those parameters, animal removal rates and joint clinical signs (lameness and joint swelling) were proposed as indicators of joint protection. Lung pathology (percent gross lung lesions) and clinical signs of coughing were proposed as indicators of lung protection. Lung lesion scores are provided in
Post-challenge, the SQ/IN two high dose vaccine group (group 1) had a lower incidence of joint swelling and removal rates, compared with the challenge control group (group 5). In addition, group 1 showed a trend in a reduced incidence of arthritis as shown in
Five animals tested positive for M. bovis antibodies prior to or on Day 0 and 5 of 9 within the challenge control group tested positive during the vaccination phase prior to challenge (see Protocol Deviation 3 & 4). Reasons for the serum titers prior to exposure may include ELISA reagent cross-reactivity, maternal antibodies and/or residual material from prior studies.
The data for this isolate passaged 135 times was compared to the data for this isolate when passaged at 106 times. Specifically, the data was compared where both passages of the isolate were administered two times subcutaneously and intranasaly. In the 135 passage study, only 1 animal out of 8 were removed from the study due to death and culling. In the 106 passage study, 4 out of 9 animals were removed from the study due to death and culling. Death and culling was reduced in the isolate passaged 135 times by 31.9%. The results are summarized in the Table 6.
Conclusions
Mycoplasma bovis vaccine candidate PTA-9666 via a simultaneous intranasal and subcutaneous route administered 2 times with a 2 week interval at a high dose level (1E9 CFU) showed a reduction of total joint swelling scores and early removal rates (joint protection) in colostrum deprived calves when challenged.
Materials and Methods
42 weaned calves negative for Mycoplasma bovis were reared. At post weaning (6 weeks±2 weeks), the calves were randomly assigned to 1 of 6 groups. Calves were allowed to adjust for six (6) days and received vaccination according to group assignment on Day 0. Approximately four (4) weeks later (Day 28) all calves were challenged with virulent M. bovis according to group assignment. Fourteen (14) days after challenge (Day 42), the calves were necropsied. Three live vaccine candidates were used to immunize the calves. They are referred to as M. bovis Live Vaccine I, M. bovis Live Vaccine II, and M. bovis Live Vaccine III. These three representative strains include 052823A106, deposited with the ATCC in Manassas, Va. on Oct. 16, 2007 under the terms of the Budapest Treaty and designated as PTA-8694 (Live VacI); 05249A102, also deposited with the ATCC in Manassas, Va. on Oct. 16, 2007 under the terms of the Budapest Treaty and designated as PTA 8696 (Live Vac II); and 0519021B106, also deposited with the ATCC in Manassas, Va. on Oct. 16, 2007 and designated as PTA 8695 (Live Vac III).
Groups 1, 2, and 3 were given Live Vaccine I on Day 0 and Day 14. Group 1 was administered 2 mL subcutaneously and 2 mL intranasally for each administration. Group II was administered 2 mL subcutaneously for each administration. Group III was administered 2 mL intranasally for each administration. Group IV was a control group and was administered 2 mL of media subcutaneously and 2 mL of media intranasally for each administration. Group V was administered Live Vaccine II on Day 0 and Day 14 at a dose of 2 mL subcutaneously and 2 mL intranasally for each administration. Group VI was given Live Vaccine III on Day 0 and Day 14 at a dose of 2 mL subcutaneously and 2 mL intranasally for each administration. All groups were challenged with virulent M. bovis on Day 28. A summary of the Study Design is illustrated in Table 7.

Microbiology
Briefly, swabs were swirled in 5 mL Mycoplasma selective broth. A small sample (approx. 5 mm) was cut from lung tissue and homogenized in 2 mL of complete Friis media. 100 ul of homogenate were added to Mycoplasma selective broth.

Histopathology/IHC
Formalin-fixed tissues were sent to ISU Veterinary Diagnostic laboratory and tested by hematoxylin/eosin stained slide and immunohistochemistry using monoclonal antibodies specific for M. bovis.
Clinical Signs
Daily general observations were carried out from Day 0 to Day 28 and then daily clinical observations made from Day 29 to euthanasia and necropsy. Clinical and general observations noted deviation from the norm and were documented.
Necropsy
Following euthanasia, each animal was necropsied. The thoracic cavity and trachea were examined for each calf and gross observations recorded on the Necropsy Report Record. The lungs and about 6 inches of trachea from each calf were removed intact for further examination and sample collection.
For each set of lungs, the dorsal and ventral lung surfaces were photographed with an appropriate ear tag alongside each view.
Lung Pathology
For each set of lungs, each lung lobe was examined by visualization and by palpation. An approximation of how much pathology was present (as a percent) per each lung lobe due to M. bovis was determined. Each lung lobe percent was then weighted and summed to determine the percentage of total lung with pathology.
Joint Pathology
Affected joints were examined and gross observations recorded.
Changes to the Study Protocol
Six animals were excluded from analysis. One animal each was excluded from Groups I, II, and III. Three animals were excluded from Group IV. The one animal in Group II was found dead with lung pathology inconsistent with M. bovis, and the rest were excluded from analysis for testing positive for M. bovis. Twenty-two animals were removed prior to study termination from Day 30-38 for humane reasons. One animal in Group 5 was removed on Day 40, prior to study termination, because the animal died by asphyxiation after becoming trapped in the feed bunk.
Results and Discussion
Post-Challenge Clinical Signs
Clinical observations were made from Day 28 through Day 42. Coughing, labored respiration, depression, swollen joints, lameness and droopy ear were clinical observations noted during this phase of the study. Clinical signs were divided into three types (respiratory, joint and other) typical of Mycoplasma bovis infection. Respiratory signs included coughing, rapid/labored respiration and nasal discharge. Joint signs included swollen joints and lameness.
Lung Pathology
At necropsy, lungs were collected and observed for lesions associated with M. bovis. Animals exhibited variability in pathological features such as consolidation and nodular lesion formation. Results of lung involvement were expressed as a percent using a scoring system, which reflects the percentage of the total lung with gross pathology associated with M. bovis infection. In some cases, determination of lung percent involvement was hampered by adhesions or the atypical nature of lesions.
Joint Pathology
At necropsy, joints from animals that previously exhibited clinical symptoms (swelling and/or lameness) were examined for gross pathology. Areas affected varied by animal and may involve the carpus, hock, stifle, fetlock and/or elbow. Animals presented with gross swelling, increased synovial fluid, abnormal fluid appearance, or thickening of the joint capsule. In more severely affected calves, fibrin was present as was erosion of the articular surface. Samples of joint fluid and/or surface swabs were tested by culture and PCR for the presence of Mycoplasma bovis.
PCR Detection of M. bovis from Nasal, Tonsil and Lung Samples
The nasal passages were sampled from each animal by swab on Day 0, 14, 27, 35 and 41 or Day of Necropsy. In addition, during the post-mortem, samples of tonsils were taken by swab and representative lung tissue was recovered. The frequency of detection using real-time PCR targeting a general M. bovis marker (uvrC) was analyzed. In addition, tonsil and lung tissue were analyzed using a recently developed end-point PCR assay targeting markers not found in the M. bovis challenge isolate but found in all vaccine candidates.
M. bovis Serology
All samples were tested in the Biovet M. bovis ELISA to monitor the serological response to M. bovis. Seroconversion was scored according to grouped multipliers of positivity ODs. The mean serological scores detected from each group on Day 0, 14, 27, 35 and Post (post represents a range of study days from 37 to 41 due to early removal of certain animals) were analyzed.
Discussion
The objective of this study was to assess the efficacy of an experimental live Mycoplasma bovis vaccine (05-2823 P106) using various 2 mL administration routes (SQ, IN, SQ+IN) fourteen days apart and a dual challenge model in the target species. The challenge model used a high volume administered to two locations of the lung with the addition of an IV administration. In addition, two other live vaccine candidates (05-249 P102 and 05-1902-1 P106) were evaluated for efficacy using only the SQ+IN route.
The challenge and vaccine candidate Mycoplasma bovis isolates originated from different naturally infected farms. The challenge isolate was previously shown to cause both lung and joint disease during experimental challenge and predominated in mixed isolate challenge studies. The live vaccine candidates are high passage isolates originally derived from diagnostic samples. High passage of the vaccine candidates was performed by serial limiting dilution in Friis base media supplemented with horse serum and yeast extract. Although no appreciable difference has been observed in the growth rate in the Friis complete media, at high passage, vaccine candidate 05-2823 P106 has demonstrated restricted growth on some Mycoplasma selective agar formulations while the low passage parent isolate shows no apparent growth restriction. Also, genotypes of the challenge and vaccine isolates are dissimilar (as determined by insertion sequence PCR fingerprinting).
The challenge procedure using a total volume of 120 mL of the challenge isolate administered to each animal resulted in the challenge only group showing lung pathology and joint involvement in all animals.
Multiple parameters were investigated during this study to access vaccine benefits. Of those parameters, animal removal rates and joint clinical symptoms were used as primary indicators of joint protection. Lung pathology (percent gross lung lesions) was used as the primary indicator of lung protection. Other data such as detection of organism from tissue, joint distribution, and serology provided additional data for conformation.
All groups showed some lung and joint protective benefit after receiving the vaccine candidate Mycoplasma bovis Live Vaccine I (05-2823 P106) regardless of route or route combination as demonstrated by a reduction in lung lesions, joint clinical symptoms and animal removal rates. The combined SQ and IN route (Group 1) resulted in the greatest reduction of lung lesions (86%) compared to the groups using only a single route. Additionally, results of lung lesions, joint clinical symptoms and removal rate reductions suggest benefit from receiving the two other vaccine candidates Live Vaccine II (05-249 P102) and Live Vaccine III (05-1902-1 P106) by a combined SQ and IN route. ELISA results demonstrated a strong humoral response to vaccination with all vaccine candidates.
All vaccine candidates demonstrated safety. No animals from any group receiving a vaccine presented with clinical symptoms during the vaccination period and only one animal that had received Live Vaccine III (05-1902-1 P106) showed reactivity at an injection site. Additionally, results of PCR showed non-challenge M. bovis detection from the tonsil tissue of only groups receiving a vaccine candidate via the IN route and detection of non-challenge from lung tissue in only a single animal that had received Live Vaccine I (05-2823 P106) by both IN and SQ routes. A comparison of serology for Live Vac I, II, II, and no vaccine where the vaccine was administered subcutaneously and intramuscularly, is provided in
Conclusions
Protective benefits (respiratory and joint) were observed for M. bovis vaccine candidates Live Vaccine I (05-2823 P106), Live Vaccine II (05-249 P102) and Live Vaccine III (05-1902-1 P106) via a simultaneous intranasal and subcutaneous route administered 2 times with a 2 week interval in colostrum deprived calves using a dual lung/joint challenge.
Protective benefits (respiratory and joint) were observed for M. bovis vaccine candidate Live Vaccine I (05-2823 P106) with either intranasal or subcutaneous route administered 2 times with a 2 week interval in colostrum deprived calves using a dual lung/joint challenge.
The DNA fingerprinting process was used to differentiate M. bovis strains by isolating, amplifying and detecting DNA using the methods and primers as disclosed in WO 2008-030619.
Materials and Methods
Mycoplasma sp. isolates were used in the studies. Isolates were obtained from in-house sources or field isolates obtained from infected animals. Isolates were grown using a combination of Mycoplasma-selective agar and broth for 1-7 days. To isolate DNA, broth cultures were spun and pelleted. DNA from the pellet was then extracted (using the Qiagen DNeasy Tissue Kit and resuspended in molecular grade water). Genomic DNA was quantitated using Picogreen (Invitrogen). Primers were designed based on the known insertion sequences (transposable elements) present in the bacterial genome (Mycoplasma bovis) and are disclosed in WO 2008-030619. Outwardly facing primers were manually selected from the element ends (excluding the terminal repeat regions) at a Tm of 55-58C. PCR reactions were then carried out using a multiplex PCR master mix (Qiagen Multiplex PCR Kit). The reactions contained 1× Master mix, 300 nM of each primer and 1 ng of template DNA. Thermal cycling conditions were 95° C. for 15 minutes, 35 cycles of 94° C. for 30 seconds, 56.1° C. for 90 seconds, 72° C. for 2 minutes, with a final extension of 72° C. for 4 minutes and a 4° C. hold. The amplified products were separated on a 4% agarose gel with ethidium bromide (Invitrogen E-gel), run for 50 minutes at room temperature and imaged under UV light.
Results and Discussion
The results showed that each of the isolates used in this application had a unique fingerprint. However, as shown in Example 2, each isolate was also an effective attenuated live culture vaccine that was effective at providing cross protection against a challenge isolate having a different fingerprint than any of the vaccine candidates. Three field isolates, 05-2823 P106 (PTA-8694), 05-249 P102 (PTA-8696), and 05-1902-1-P106 (PTA-8695), were grown and DNA isolated according to the above protocol. 2-5 ng of DNA from each isolate was amplified according to the above protocol using a multiplex of 4 sets of IS primers identified as SEQ ID Nos. 1-8 as disclosed in WO 2008-030619. The amplified products were separated on a Invitrogen E-gel 4% agarose gel containing ethidium bromide (according to manufacturer) for 50 minutes and visualized under UV light. All isolates produced unique patterns. The patterns were reproducible using independent aliquots under the sample PCR reaction conditions.
The study in Example 2 used the Mycoplasma bovis vaccine at the lower passage 106, and measured the effectiveness in protecting vaccinated calves from 3 key manifestations of Mycoplasma bovis disease: clinical signs of respiratory disease, lameness, and “early removal” or euthanasia and death resulting from a severe myriad of clinical signs caused by Mycoplasma bovis disease. The latter manifestation of disease is obviously most consequential, and hence, was considered the most important feature of vaccine efficacy. This most important parameter was used to measure any differences in efficacy between vaccine at passage 106 and passage 135.
In the study described in Example 2 with passage 106 vaccine, Group 1 (Live Vac I SQ+IN) received vaccine twice at 14 day intervals and via two routes of administration, intranasal (IN) and subcutaneously (SQ), at each vaccination event. Separate groups of calves were also vaccinated with passage 106 vaccine. Most pertinent was Group 2 (Live Vac I SQ) which was given vaccine twice at 14 day intervals but via one route of administration, only subcutaneously (SQ), at each vaccination event.
Following vaccination, both the vaccinated Group 1 and Group 2 and a separate assembly (Group 4) of non-vaccinated (No Vac) calves were purposely exposed to virulent Mycoplasma bovis delivered directly into each calf. Disease resulting from the challenge exposure was measured and compared among the groups, and specifically, comparing the most significant disease “early removal” (death) in vaccinated Group 1 and Group 2 to the non-vaccinated (No Vac) calves of Group 4 to measure the effectiveness of the passage 106 vaccine. As presented in Table 8, passage 106 vaccinated Group 2 given vaccine twice at 14 day intervals but via one route of administration, subcutaneously, provided a notable 56% reduction in death/euthanasia. Group 1 (Live Vac I SQ+IN) given passage 106 vaccine twice at 14 day intervals and via two routes of administration, intranasal (IN) and subcutaneously (SQ), at each vaccination event, provided the same notable 56% reduction in death/euthanasia of vaccinated calves.
In this study the Mycoplasma bovis vaccine at the higher passage 135 was also evaluated for its effectiveness in protecting vaccinated calves from the most important manifestation of Mycoplasma bovis disease, “early removal rates” or euthanasia and death resulting from a severe myriad of clinical signs caused by Mycoplasma bovis disease. In the study described in Example 1, Group 1 also received vaccine twice at 14-day intervals via two routes of administration, intranasal (IN) and subcutaneously (SQ), at each vaccination event as was done in the study described in Example 2, with passage 106 vaccine. However, the critical difference between the vaccines in Group 1 of each of these two studies was passage level. In the study of Example 2 Group 1 was given vaccine at passage level 106, and in this second Study of Example 1 Group 1 received vaccine at the higher passage 135.
Separate groups of calves were also vaccinated with passage 135 vaccine in the study described in Example 1. Most pertinent again was Group 2 which was given vaccine only once via one route of administration, subcutaneously (SQ). Following vaccination, both the vaccinated Group 1 and Group 2 and a separate assembly (Group 5) of non-vaccinated calves were purposely exposed to virulent Mycoplasma bovis delivered directly into each calf. Disease resulting from the challenge exposure was measured and compared among the groups. Specifically, efficacy was determined by comparing the most significant disease “early removal rates” (death) in vaccinated Group 1 and Group 2 to the non-vaccinated calves of Group 5 to measure the effectiveness of the passage 135 vaccine. As presented in Table 10, Group 1 given passage 135 vaccine twice at 14 day intervals via two routes of administration, intranasal (IN) and subcutaneously (SQ), at each vaccination event provided a quite unanticipated and very high effectiveness by reducing calf early removal rates (death) by 83%, or much higher efficacy than was achieved with passage 106 vaccine that provided a notable but lower 56% reduction of early removal rates. The comparative results between the two studies appear in Table 11.
Also unanticipated was the efficacy achieved in Group 2 the study of Example 1, with a single dose of vaccine. Group 2 received just a single dose of passage 135 vaccine via one route of administration, subcutaneously. This higher passage 135 vaccine provided a 55.6% (56%) reduction in calf death/euthanasia. By contrast, the 106 passage vaccine required two doses of vaccine, a priming dose followed by a booster 14 days later in the study of Example 2 to achieve comparable efficacy delivered in just one dose (no booster needed) to calves receiving passage 135 vaccine in the study of Example 1.

apassage 135 vaccine provides unanticipated reduction in death due to M. bovis compared to passage 106
bpassage 135 vaccine is effective as single dose without need for booster, whereas passage 106 requires a booster for comparable reduction in death due to M. bovis
Hence, the passage 135 vaccine yielded an improved and unexpectedly higher level of efficacy by significantly reducing death due to Mycoplasma bovis infection using a more convenient, less costly single dose of vaccine, whereas the lower passage 106 vaccine required two doses of vaccine to provide comparable efficacy. In addition, substantially better efficacy of 83% reduction in death was achieved with high passage Group 1 of the study of Example 1 using an identical vaccination regimen as used with low passage Group 1 of the study of Example 2, the only difference being the passage 135 vaccine in the former and passage 106 vaccine in the latter study. The passage 135 vaccine reduced death due to Mycoplasma bovis by 83% as compared to a lower but notable efficacy with passage 106 vaccine of 56%. Typically the efficacy of a vaccine is reduced on progressive passages in vitro as the microorganism further adapts to cell culture and loses expression of potentially immunogenic virulence proteins. Unexpectedly, the avirulent M. bovis vaccine of this invention demonstrated improved effectiveness in response to higher in vitro passages, and specifically in progressing from passage 106 to passage 135 vaccine.
Materials and Methods
An M. bovis, avirulent live bacterial culture in lyophilized presentation that was rehydrated with sterile water diluent was used at 2×2 mL doses administered at 2 to 3 week intervals via subcutaneous injection in cattle 6 weeks of age or older.
The study design utilized 3 vaccine treated groups and 1 placebo treated each containing 15 to 17 calves. Test animals all received two subcutaneous doses of experimental vaccines formulated at 3 different antigen levels or a placebo vaccine composed of the media used to produce the Mycoplasma Bovis culture. Calves were 6-weeks of age at the time of administration of the first dose of vaccine or placebo. Calves were challenged on day 42 and post-challenge observations were made for 28 days. Primary parameters of mortality/culling, and lameness and joint swelling on any day were observed to assess the efficacy of the vaccine.
Table 12 summarizes the conclusions made from the analysis of the data.
Conclusions
A preferred dose of 108.9 CCU50 was efficacious as assessed.
Materials and Methods
An M. bovis, avirulent live bacterial culture in lyophilized presentation that was rehydrated with sterile water diluent was used at 2×2 mL doses administered at 2 to 3 week intervals via subcutaneous injection in cattle 6 weeks of age or older.
The dissemination and transmission of the vaccine strain was also evaluated in colostrum deprived calves. In this study >10 logs of low passage, Master seed-derived (MS+3) was administered via the subcutaneous route to 10 calves. Samples including 15 different tissues and swabs were collected from treated calves at weekly intervals for 5 weeks after administration. To assess transmission of the vaccine, 10 sentinel calves were comingled with the vaccinated calves throughout the study. Table 13 shows the results of this study.
Mycoplasma bovis
Conclusions
The 14 day sampling was the only recovery of Mycoplasma bovis vaccine, avirulent live culture, and only in one tonsil tissue sample from a single calf in the vaccinated group. The remaining 129 samples collected from dosed calves from day 7 through day 35 after vaccination were all negative for M. bovis.
Within this study, an equal number of sentinel calves were commingled with the vaccinated calves. No M. bovis was isolated from any of the swab samples or tissues from the sentinel calves.
The data from Examples 5 and 6 demonstrated the safety and efficacy of the vaccine of the present invention. The vaccines of the present invention were highly effective in preventing disease due to M. bovis following two subcutaneous injections at the minimum immunizing dose (108.9/dose). The safety evaluations in young, highly susceptible colostrum deprived (CD) calves confirmed the safety of a 20-fold overdose injected subcutaneously. The safety studies also demonstrated the vaccine is safe when injected subcutaneously.
Attenuated live BVDV type 1 and 2 strains, having at least one mutation in the coding sequence for glycoprotein Erns and/or at least another mutation in the coding sequence for Npro, wherein said mutation in the coding sequence for glycoprotein Erns leads to inactivation of RNase activity residing in Erns and/or said mutation in the coding sequence for Npro leads to inactivation of said Npro (as described in WO2005/111201, hereby entirely incorporated by reference), are grown in MDBK-cells until a TCID50 of about 105.0 to 108.1 per ml cell culture fluid. A live attenuated strain of IBR is grown in MDBK cells until a TCID50 of about 105.0 to 108.6 per ml cell culture fluid. A live attenuated strain of M. bovis as described above is grown in MDBK cells until a CFU of about 1010 per ml cell culture fluid. Each culture fluids are collected. Equal amounts of the antigens are mixed and lyophilized by standard techniques. For reconstitution, an aqueous solution is used. One dose of the combination vaccine contains 2 ml of the reconstituted antigens. A final dose includes IBR (105.0 to 108.6 TCID50), BVDV-1 (105.0 to 108.1 TCID50), BVDV-2 (105.0 to 108.1 TCID50), and M. bovis (2.1×109. CFU).
The preparation of the IBR, BVDV 1 and 2 and M. bovis antigens are grown as described for vaccine A. In addition, a live attenuated strain of PI3 is grown in MDBK cells until a TCID50 of about 104.2 to 106.5 per ml cell culture fluid. Afterwards, the PI3 containing culture fluid is harvested. An amount of 104.2 to 106.5 (TCID50) of the PI3 antigen is mixed with the IBR, and BVDV types 1 and 2. The mixture is then lyophilized by standard techniques, so that one dose of the reconstituted combination vaccine contains 2 ml as described for Vaccine A. A final dose includes IBR (105.0 to 108.6 TCID50), BVDV-1 (105.0 to 108.1 TCID50), BVDV-2 (105.0 to 108.1 TCID50), M. bovis (2.1×109. CFU), and PI3 (104.2 to 106.5 TCID50).
