Patent Application
20220218764
The present disclosure relates to isolated and biologically pure microorganisms that have applications, inter alia, in the treatment of colic in equines. The disclosed microorganisms can be utilized in their isolated and biologically pure states, as well as being formulated into compositions.
The equine industry is a vital economic component of our economy, which produces horses for aid in work, show, entertainment, racing, rodeo, and companionship. There are over 70 different types of equine colic. Many of these are attributed to microbes. Others are likely but not confirmed to be microbial and some have no link to microbes. Some early stage microbial-based forms of colic are the precipice for many other forms of colic. This is caused by a healthy horse or other equine being induced through internal or external pressures to colic-like state. This temporal colic can either correct naturally back to the healthy state or progress into the many other types of symptomatic colic. Induction of colic can often occur through emotional, physical, and/or immunomodulatory stress as well as poor diet.

The ability to return to a healthy state after perturbation is in part regulated by the microbial populations and biochemical functions of the gut. A supplemented group of microbes isolated from the horse or other equine gut can regulate the community to a healthy state. The ability to properly regulate the gut microbial community to a healthy state can prevent early-stage colic from negative internal or external pressures as well as prevent the downward spiral from early stage-colic to other forms of severe colic. A supplemented group of microbes can be administered daily via animal feed, supplement, or water to prevent disease onset and progression. Such a supplement can also be administered by fecal transplant and/or directly to target organs during pre/post/during surgery to treat a horse or other equine in a pre-existing chronic state.
The disclosure is generally drawn to methods of administering one or more microbes of the present disclosure to equines. In some aspects, the disclosure is generally drawn to methods for treating or preventing colic in equines, the method comprising: administering to an equine an effective amount of a microbial composition comprising: (i) any one or more of the bacteria set forth in Table 2; and (ii) a carrier suitable for equine administration,
In some aspects, the disclosure is generally drawn to a microbial composition capable of treating or preventing colic in an equine, comprising: (i) a purified population of bacteria comprising one or more bacteria selected from Table 2; and (ii) a carrier suitable for equine administration, wherein the purified population of bacteria is present in the composition in an amount effective to reduce colic symptoms and/or shift the gut microbiome, as compared to an equine not having been administered the composition. In some embodiments, the bacteria are encapsulated. In some embodiments, the microbial composition is shelf stable.
In some aspects, the microbial composition is administered via a fecal transplant from a health! equine. In some aspects, the microbial composition is administered in addition to a fecal transplant from a healthy equine. In some aspects, the microbial composition is administered orally. In further aspects, the oral administration includes administering the microbial composition sprayed onto or mixed into food/feed. In some aspects, the microbial composition is administered rectally. In further aspects, rectal administration includes administering the microbial composition as a suppository. In some aspects, the microbial composition is administered during equine surgery. In some aspects, the microbial composition is administered after equine surgery. In some aspects, the microbial composition is administered before equine surgery.
In some embodiments, the present disclosure provides microbial compositions suitable for administration to an equine. In some embodiments, the present disclosure provides methods of preventing and/or treating colic in an equine. Herein, the term “equine animal” may be used interchangeably with the term “equine” and encompasses any member of the genus Equus. It encompasses, e.g., any horse or pony, the taxonomic designations Equus ferus and/or Equus caballus, and/or the subspecies Equus ferus caballus. The equine animal may, e.g., be a domestic or wild horse, zebra, mule, or donkey.
The term colic generally refers to abdominal pain. Throughout the years, it has become a broad term for a variety of conditions that cause a horse to exhibit clinical signs of abdominal pain. Consequently, it is used to refer to conditions of widely varying etiologies and severity. Numerous clinical signs are associated with colic. The most common include one or more of pawing repeatedly with a front foot, looking bad(at the flank region, curling the upper lip and arching the neck, repeatedly raising a rear leg or kicking at the abdomen, lying down, rolling from side to side, sweating, stretching out as if to urinate, straining to defecate, distention of the abdomen, loss of appetite, depression, and/or decreased number of bowel movements.
A colic diagnosis can be made and appropriate treatment begun after examination of the horse, considering the history of any previous problems or treatments, determining which part of the intestinal tract is involved, and identifying the cause of the particular episode of colic. The physical examination should include assessment of the cardiopulmonary and GI systems. The oral mucous membranes should be evaluated for color, moistness, and capillary refill time. The mucous membranes may become cyanotic or pale in horses with acute cardiovascular compromise and eventually hyperemic or muddy as peripheral vasodilation develops later in shock. The capillary refill time (normal ˜1.5 sec) may be shortened early but usually becomes prolonged as vascular stasis (venous pooling) develops. The membranes become dry as the horse becomes dehydrated. The heart rate increases due to pain, hemoconcentration, and hypotension; therefore, higher heart rates have been associated with more severe intestinal problems (strangulating obstruction). However, it is important to note that not all conditions requiring surgery are accompanied by a high heart rate.
An important aspect of the physical examination is the response to passing a nasogastric tube. Because horses can neither regurgitate nor vomit, adynamic ileus, obstructions involving the small intestine, or distention of the stomach with gas or fluid may result in gastric rupture. Passing a stomach tube may, therefore, save the horse's life and assist in diagnosis of these conditions. If fluid reflux occurs, the volume and color of the fluid should be noted. In healthy horses, it is common to retrieve <1 L of fluid from the stomach.
The most definitive part of the examination is the rectal examination. The veterinarian should develop a consistent method of palpating for the following: aorta, cranial mesenteric artery, cecal base and ventral cecal hand, bladder, peritoneal surface, inguinal rings in stallions and geldings or the ovaries and uterus in mares, pelvic flexure, spleen, and left kidney. The intestine should be palpated for size, consistency of contents (gas, fluid, or impacted ingesta), distention, edematous walls, and pain on palpation. In healthy horses, the small intestine cannot be palpated; with small-intestinal obstruction, strangulating obstruction, or enteritis, the distended duodenum can be palpated dorsal to the base of the cecum on the right side of the abdomen, and distended loops of jejunum can be identified in the middle of the abdomen.
A sample of peritoneal fluid (obtained via paracentesis performed aseptically on midline) often reflects the degree of intestinal damage. The color, cell count and differential, and total protein concentration should be evaluated. Normal peritoneal fluid is clear to yellow, contains <5,000 WBCs/μL (most of which are mononuclear cells), and <2.5 g of proteinidL.
The age of the horse is important, because a number of age-related conditions cause colic. The more common of these include the following: in foals—atresia coli, meconium retention, uroperitoneum, and gastroduodenal ulcers; in yearlings—ascarid impaction; in the young small-intestinal intussusception, nonstrangulating infarction, and foreign body obstruction; in the middle-aged cecal impaction, enteroliths, and large-colon volvulus; and in the aged pedunculated lipoma and mesocolic rupture.
In most instances, colic develops for one of four reasons: 1) The wall of the intestine is stretched excessively by either gas, fluid, or ingesta. This stimulates the stretch-sensitive nerve endings located within the intestinal wall, and pain impulses are transmitted to the brain. 2) Pain develops due to excessive tension on the mesentery, as might occur with an intestinal displacement. 3) Ischemia develops, most often as a result of incarceration or severe twisting of the intestine. 4) Inflammation develops and may involve either the entire intestinal wall (enteritis) or the covering of the intestine (peritonitis). Under such circumstances, pro-inflammatory mediators in the wall of the intestine decrease the threshold for painful stimuli.
The list of possible conditions that cause colic is long, and it is reasonable first to determine the most likely type of disease and begin appropriate treatments and then to make a more specific diagnosis, if possible. The general types of disease that cause colic include excessive gas in the intestinal lumen (flatulent colic), simple obstruction of the intestinal lumen, obstruction of both the intestinal lumen and the blood supply to the intestine (strangulating obstruction), interruption of the blood supply to the intestine alone (nonstrangulating infarction), inflammation of the intestine (enteritis), inflammation of the lining of the abdominal cavity (peritonitis), erosion of the intestinal lining (ulceration), and “unexplained colic.”
Horses with colic may need either medical or surgical treatments. Almost all require some form of medical treatment, but only those with certain mechanical obstructions of the intestine need surgery. The type of medical treatment is determined by the cause of colic and the severity of the disease. In some instances, the horse may be treated medically first and the response evaluated; this is particularly appropriate if the horse is mildly painful and the cardiovascular system is functioning normally. Ultrasonography can be used to evaluate the effectiveness of nonsurgical treatment. If necessary, surgery can be used for diagnosis as well as treatment.
If evidence of intestinal obstruction with dry ingesta is found on rectal examination, a primary aim of treatment is to rehydrate and evacuate the intestinal contents. If the horse is severely painful and has clinical signs indicating loss of fluid from the bloodstream (high heart rate, prolonged capillary refill time, and discoloration of the mucous membranes), the initial aims of treatment are to relieve pain, restore tissue perfusion, and correct any abnormalities in the composition of the blood and body fluids. If damage to the intestinal wall (as a result of either severe inflammation or a displacement or strangulating obstruction) is suspected, steps should be taken to prevent or counteract the ill effects of bacterial endotoxins that cross the damaged intestinal wall and enter the bloodstream. Finally, if there is evidence the colic episode is caused by parasites, one aim of treatment is to eliminate the parasites.
The microbiomes of healthy and colicking equines differ significantly.
Machine learning algorithms can be used to determine if a patient is in a colic or non-colic state.
The differences in the microbiome of healthy equines compared to equines in various states of colic is further illustrated in
Additional differences in microbiomes of healthy and colic horses are illustrated by MIC scores. As shown in
The microbial state of horses over time through periods of colic and non-colic further emphasize the differences between the microbiomes of healthy and colic horses. As shown in
Principal coordinate analysis can also be used to determine the efficacy of fecal transplant, as shown in
In some embodiments, the present disclosure provides microbial compositions comprising one or more target microbes. The target microbe may be any microorganisms suitable for use according to the present disclosure. As used herein the term “microorganism” should be taken broadly. It includes, but is not limited to, the two prokaryotic domains, Bacteria and Archaea, as well as eukaryotic fungi, protists, and viruses. By way of example, the microorganisms may include species of the genera of: Arcanobacterium, Acidaminococcus, Phascolarctobacteriunt, Bacteroides, Suiterella, Sutterella, Duodenibacillus, Catabacter, Christensenella, Gostridium, Clostridium serosa stricto, Anaerococcus, Finegohlia, Parvimonas, and Helcococcus, Anaerovorax, Ihubacter, Mogibacterium, Corynebacterium, Algoriphagus, Cecembia, Flavobacterium, Atlantibacter, Escherichia, Shigella, Erysipelothrix, Spiroplasma, Eubacterium, Flavobacterium, Devosia, Alaritalea, Anaerocolunma, Anaerostipes, Butyrivibrio, Coprococcus, Cellrrlosilyticrrnr Clostridium XIVa, Fkisingicoccus, Howardella, Oribacterium, Pediococcus, Peptococcus, Peptoniphilus, Terrisporobacter Peptostreptococcus, Barnesiella, Butyricimonas, Pamhacteroides, Poiplivromonas, Prevotella, Odoribacter, Alloprevotella, Bacteroides, Prevotella, Anaerocella Alistipe, Oscillibacter, Clostridium 111, Intestinimonas, Ruminiclostridium, Monoglobus, Pedobacter, Streptococcus, Schwartzia, Selenomonas, Phascolarctobacterium, and Negativicoccus.
In some embodiments, the microbes are obtained from animals (e.g., mammals, reptiles, birds, and the like), soil (e.g., rhizosphere), air, water (e.g., marine, freshwater, wastewater sludge), sediment, oil, plants (e.g., roots, leaves, stems), agricultural products, and extreme environments (e.g., acid mine drainage or hydrothermal systems). In some embodiments, the microbes are obtained from marine or freshwater environments such as an ocean, river, or lake. In some embodiments, the microbes can be from the surface of the body of water, or any depth of the body of water (e.g., a deep sea sample).
The microorganisms of the disclosure may be isolated in substantially pure or mixed cultures. They may be concentrated, diluted, or provided in the natural concentrations in which they are found in the source material. For example, microorganisms from saline sediments may be isolated for use in this disclosure by suspending the sediment in fresh water and allowing the sediment to fall to the bottom. The water containing the bulk of the microorganisms may be removed by decantation after a suitable period of settling and either administered to the GI tract of an ungulate, or concentrated by filtering or centrifugation, diluted to an appropriate concentration and administered to the GI tract of an ungulate with the bulk of the salt removed. By way of further example, microorganisms from mineralized or toxic sources may be similarly treated to recover the microbes for application to the ungulate to minimize the potential for damage to the animal.
In some embodiments, the microorganisms are used in a crude form, in which they are not isolated from the source material in which they naturally reside. For example, the microorganisms are provided in combination with the source material in which they reside; for example, fecal matter, cud, or other composition found in the gastrointestinal tract. In such embodiments, the source material may include one or more species of microorganisms.
In some embodiments, a mixed population of microorganisms is used in the methods of the disclosure. In embodiments of the disclosure where the microorganisms are isolated from a source material (for example, the material in which they naturally reside), any one or a combination of a number of standard techniques Which will be readily known to skilled persons may be used. However, by way of example, these in general employ processes by which a solid or liquid culture of a single microorganism can be obtained in a substantially pure form, usually by physical separation on the surface of a solid microbial growth medium or by volumetric dilutive isolation into a liquid microbial growth medium. These processes may include isolation from dry material, liquid suspension, slurries or homogenates in which the material is spread in a thin layer over an appropriate solid gel growth medium, or serial dilutions of the material made into a sterile medium and inoculated into liquid or solid culture media.
In some embodiments, the material containing the microorganisms may be pre-treated prior to the isolation process in order to either multiply all microorganisms in the material. Microorganisms can then be isolated from the enriched materials.
The target microbes can be derived from any sample type that includes a microbial community. For example, samples for use with the present disclosure encompass without limitation, an animal sample (e.g., mammal, reptile, bird), soil, air, water (e.g., marine, freshwater, wastewater sludge), sediment, oil, plant, agricultural product, plant, soil (e.g., rhizosphere) and extreme environmental sample (e.g., acid mine drainage, hydrothermal systems). In the case of marine or freshwater samples, the sample can be from the surface of the body of water, or any depth of the body water, e.g., a deep sea sample. The water sample, in one embodiment, is an ocean, river, or lake sample.
In some embodiments, the animal sample is a body fluid. In some embodiments, the animal sample is a tissue sample. Non-limiting animal samples include tooth, perspiration, fingernail, skin, hair, feces, urine, semen, mucus, saliva, gastrointestinal tract. The animal sample can be, for example, a human, primate, bovine, porcine, canine, feline, rodent (e.g., mouse or rat), equine, or bird sample. In some embodiments, the bird sample comprises a sample from one or more chickens. In some embodiments, the sample is a human sample. The human microbiome comprises the collection of microorganisms found on the surface and deep layers of skin, in mammary glands, saliva, oral mucosa, conjunctiva, and gastrointestinal tract. The microorganisms found in the microbiotne include bacteria, fungi, protozoa, viruses, and archaea. Different parts of the body exhibit varying diversity of microorganisms. The quantity and type of microorganisms may signal a healthy or diseased state for an individual. The number of bacteria taxa are in the thousands, and viruses may be as abundant. The bacterial composition for a given site on a body varies from person to person, not only in type, but also in abundance or quantity.
In another embodiment, the sample is a soil sample (e.g., bulk soil or rhizosphere sample). It has been estimated that 1 gram of soil contains tens of thousands of bacterial taxa, and up to 1 billion bacteria cells as well as about 200 million fungal hyphae (Wagg et al. (2010). Proc Natl. Acad. Sci. USA 111, pp. 5266-5270, incorporated by reference in its entirety for all purposes). Bacteria, actinomycetes, fungi, algae, protozoa, and viruses are all found in soil. Soil microorganism community diversity has been implicated in the structure and fertility of the soil microenvironment, nutrient acquisition by plants, plant diversity and growth, as well as the cycling of resources between above- and below-ground communities. Accordingly, assessing the microbial contents of a soil sample over time and the co-occurrence of active microorganisms (as well as the number of the active microorganisms) provides insight into microorganisms associated with an environmental metadata parameter such as nutrient acquisition and/or plant diversity.
The soil sample in one embodiment is a rhizosphere sample, i.e., the narrow region of soil that is directly influenced by root secretions and associated soil microorganisms. The rhizosphere is a densely populated area in which elevated microbial activities have been observed and plant roots interact with soil microorganisms through the exchange of nutrients and growth factors (San Miguel et at (2014). Appl. Microbiol. Biotechnol, DOI 10.1007/s00253-014-5545-6, incorporated by reference in its entirety for all purposes). As plants secrete many compounds into the rhizosphere, analysis of the organism types in the rhizosphere may be useful in determining features of the plants which grow therein.
In another embodiment, the sample is a marine or freshwater sample. Ocean water contains up to one million microorganisms per milliliter and several thousand microbial types. These numbers may be an order of magnitude higher in coastal waters with their higher productivity and higher load of organic matter and nutrients. Marine microorganisms are crucial for the functioning of marine ecosystems; maintaining the balance between produced and fixed carbon dioxide; production of more than 50% of the oxygen on Earth through marine phototrophic microorganisms such as Cyanobacteria, diatoms and pico- and nanophytoplankton; providing novel bioactive compounds and metabolic pathways; ensuring a sustainable supply of seafood products by occupying the critical bottom trophic level in marine foodwebs. Organisms found in the marine environment include viruses, bacteria, archaea, and some eukarya. Marine viruses may play a significant role in controlling populations of marine bacteria through viral lysis. Marine bacteria are important as a food source for other small microorganisms as well as being producers of organic matter. Archaea found throughout the water column in the ocean are pelagic Archaea and their abundance rivals that of marine bacteria.
In another embodiment, the sample comprises a sample from an extreme environment, i.e., an environment that harbors conditions that are detrimental to most life on Earth. Organisms that thrive in extreme environments are called extremophiles. Though the domain Archaea contains well-known examples of extremophiles, the domain bacteria can also have representatives of these microorganisms. Extremophiles include: acidophiles which grow at pH levels of 3 or below; alkaliphiles which grow at pH levels of 9 or above; anaerobes such as Spinoloricus Cinzia which does not require oxygen for growth; cryptoendoliths which live in microscopic spaces within rocks, fissures, aquifers and faults filled with groundwater in the deep subsurface; halophiles which grow in about at leak 0.2M concentration of salt; hyperthermophiles which thrive at high temperatures (about 80-122° C.) such as found in hydrothermal systems; hypoliths which live underneath rocks in cold deserts; lithoautotrophs such as Nitrosomonas europaea which derive energy from reduced mineral compounds like pyrites and are active in geochemical cycling; metallotolerant organisms which tolerate high levels of dissolved heavy metals such as copper, cadmium, arsenic and zinc; oligotrophs Which grow in nutritionally limited environments; ostnophiles which grow in environments with a high sugar concentration; piezophiles (or barophiles) which thrive at high pressures such as found deep in the ocean or underground; psychrophiles/cryophiles which survive, grow and/or reproduce at temperatures of about −15° C. or lower; radioresistant organisms which are resistant to high levels of ionizing radiation; thermophiles which thrive at temperatures between 45-122° C.; xerophiles which can grow in extremely dry conditions. Polyextremophiles are organisms that qualify as extremophiles under more than one category and include thermoacidophiles (prefer temperatures of 70-80° C. and pH between 2 and 3). The Crenarchaeota group of Archaea includes the thermoacidophiles.
The sample can include microorganisms from one or more domains. For example, in some embodiments, the sample comprises a heterogeneous population of bacteria and/or fungi (also referred to herein as bacterial or fungal strains). For example, the one or more microorganisms can be from the domain Bacteria, Archaea, Eukarya or a combination thereof. Bacteria and Archaea are prokaryotic, having a very simple cell structure with no internal organelles. Bacteria can be classified into gram positive/no outer membrane, gram negative/outer membrane present and ungrouped phyla. Archaea constitute a domain or kingdom of single-celled microorganisms. Although visually similar to bacteria, archaea possess genes and several metabolic pathways that are more closely related to those of eukaryotes, notably the enzymes involved in transcription and translation. Other aspects of archaeal biochemistry are unique, such as the presence of ether lipids in their cell membranes. The Archaea are divided into four recognized phyla: Thaumarchaeota, Aigarchaeota, Crenarchaeota, and Korarchaeota.
The domain of Eukarya comprises eukaryotic organisms, which are defined by membrane-bound organelles, such as the nucleus. Protozoa are unicellular eukaryotic organisms. All multicellular organisms are eukaryotes, including animals, plants, and fungi. The eukaryotes have been classified into four kingdoms: Protista, Plantae, Fungi, and Animalia. However, several alternative classifications exist. Another classification divides Eukarya into six kingdoms: Excavate (various flagellate protozoa); amoebozoa (lobose atnoeboids and slime filamentous fungi); Opisthokonta (animals, fungi, choanoflagellates); Rhiza.ria (Foraminifera, Radiolaria, and various other amoeboid protozoa); Chromalveolata (Stramenopiles algae, diatoms), Haptophyta., Ctyptophyta. (or cryptomonads), and Alveolate); Archaeplastida/Primoplantae (Land plants, green algae, red algae, and glaucophytes).
Within the domain of Eukarya, fungi are microorganisms that are predominant in microbial communities. Fungi include microorganisms such as yeasts and filamentous fungi as well as the familiar mushrooms. Fungal cells have cell walls that contain glucans and chitin, a unique feature of these organisms. The fungi form a single group of related organisms, named the Eumycota that share a common ancestor. The kingdom Fungi has been estimated at 1.5 million to 5 million species, with about 5% of these having been formally classified. The cells of most fungi grow as tubular, elongated, and filamentous structures called hyphae, which may contain multiple nuclei. Some species grow as unicellular yeasts that reproduce by budding or binary fission. The major phyla (sometimes called divisions) of fungi have been classified mainly on the basis of characteristics of their sexual reproductive structures. Currently, seven phyla are proposed: _Microsporidia, Chytridiomycota, Blastocladiomycota, Neocallimastigomycota, Glomeromycota, Ascomycota, and Basidiomycota.
Microorganisms for detection and quantification by the methods described herein can also be viruses. A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses can infect all types of life forms in the domains of Eukarya, Bacteria, and Archaea. Virus particles (known as virions) consist of two or three parts: (i) the genetic material which can be either DNA or RNA; (ii) a protein coat that protects these genes; and in some cases (iii) an envelope of lipids that surrounds the protein coat when they are outside a cell. Seven orders have been established for viruses: the Caudovirales, Herpesvirales, Ligamenvirales, Mononegarirales, Nidovirales, Picornavirales, and Tymovirales. Viral genomes may be single-stranded (ss) or double-stranded (ds). RNA or DNA, and may or may not use reverse transcriptase (RT). In addition, ssRN.A viruses may be either sense (+) or antisense (−). This classification places viruses into seven groups: I: dsDNA viruses (such as Adenoviruses, Herpesviruses, Poxviruses); (+) ssDNA viruses (such as Parvoviruses); dsRNA viruses (such as Reoviruses); (+)ssRNA viruses (such as Picornaviruses, Togaviruses); V: (−)snRNA viruses (such as Orthomyxoviruses, Rhabdoviruses); VI: (+)ssRNA-RT viruses with DNA intermediate in life-cycle (such as Retroviruses); VII: dsDNA-RT viruses (such as Hepa.dnaviruses),
Microorganisms for detection and quantification by the methods described herein can also be viroids. Viroids are the smallest infectious pathogens known, consisting solely of short strands of circular, single-stranded RNA without protein coats. They are mostly plant pathogens, some of which are of economic importance. Viroid genomes are extremely small in size, ranging from about 246 to about 467 nucleobases.
As used herein, “isolate”, “isolated”, “isolated microbe”, and like terms, are intended to mean that the one or more microorganisms has been separated from at least one of the materials with which it is associated in a particular environment (for example soil, water, animal tissue). Thus, an “isolated microbe” does not exist in its naturally occurring environment; rather, it is through the various techniques described herein that the microbe has been removed from its natural setting and placed into a non-naturally occurring state of existence. Thus, the isolated strain may exist as, for example, a biologically pure culture, or as spores (or other forms of the strain) in association with an acceptable carrier.
In certain aspects of the disclosure, the isolated microbes exist as isolated and biologically pure cultures. It will be appreciated by one of skill in the art, that an isolated and biologically pure culture of a particular microbe, denotes that said culture is substantially free (within scientific reason) of other living organisms and contains only the individual microbe in question. The culture can contain varying concentrations of said microbe. The present disclosure notes that isolated and biologically pure microbes often necessarily differ from less pure or impure materials. See, e.g., In re Bergstrom, 427 F.2d 1394, (CCPR, 1970) (discussing purified prostaglandins), see also, In re _Berg)), 596 17.2d 952 (COPA 1979)(discussing purified microbes), see also, Parke-Davis & Co. v. 111(e.g., Mu ford & Co., 189 F. 95 (S.D.N.Y. 1911) (Learned Hand discussing purified adrenaline), ajf'd in part, rev'd in part, 196 F. 496 (2d Cir. 1912), each of which are incorporated herein by reference, Furthermore, in some aspects, the disclosure provides for certain quantitative measures of the concentration, or purity limitations, that must be found within an isolated and biologically pure microbial culture, The presence of these purity values, in certain embodiments, is a further attribute that distinguishes the presently disclosed microbes from those microbes existing in a natural state. See, e.g., Merck & Co. v. Olin Mathieson Chemical Corp., 253 F 2d 156 (4th Cir, 1958) (discussing purity limitations for vita in B12 produced by microbes), incorporated herein by reference.

In some embodiments, the isolated microbial strains in the compositions described herein have been genetically modified. In some embodiments, the genetically modified or recombinant microbes comprise polynucleotide sequences which do not naturally occur in said microbes. In some embodiments, the microbes may comprise heterologous polynucleotides. In further embodiments, the heterologous polynucleotides may be operably linked to one or more polynucleotides native to the microbes.
In some embodiments, the heterologous polynucleotides may be reporter genes or selectable markers. In some embodiments, reporter genes may be selected from any of the family of fluorescence proteins (e.g., GFP, RFP, YFP, and the like), β-galactosidase, or luciferase. In some embodiments, selectable markers may be selected from neomycin phosphotransferase, hygromycin phosphotransferase, aminoglycoside adenyltransferase, dihydrofolate reductase, acetolactase synthase, brornoxynil nitrilase, β-glucuronidase, dihydrofolate reductase, and chloramphenicol acetyltransferase. In some embodiments, the heterologous polynucleoti de may be operably linked to one or more promoter.
In some embodiments, the isolated microbes are identified by ribosomal nucleic acid sequences, Ribosomal RNA genes (rDNA), especially the small subunit ribosomal RNA genes, i.e., 18S rRNA genes (18S rDNA) in the case of eukaryotes and 16S rRNA (16S rDNA) in the case of prokaryotes, have been the predominant target for the assessment of organism types and strains in a microbial community. However, the large subunit ribosomal RNA genes, 28S rDNAs, have been also targeted, rDNAs are suitable for taxonomic identification because: (i) they are ubiquitous in all known organisms; (ii) they possess both conserved and variable regions; (iii) there is an exponentially expanding database of their sequences available for comparison. In community analysis of samples, the conserved regions serve as annealing sites for the corresponding universal PCR and/or sequencing primers, whereas the variable regions can be used for phylogenetic differentiation. In addition, the high copy number of rDNA in the cells facilitates detection from environmental samples.
The internal transcribed spacer (ITS), located between the 185 rDNA and 28S rDNA, has also been targeted. The ITS is transcribed but spliced away before assembly of the ribosomes. The ITS region is composed of two highly variable spacers, ITS1 and ITS2, and the intercalary 5.8S gene. This rDNA operon occurs in multiple copies in genomes. Because the ITS region does not code for ribosome components, it is highly variable. In some embodiments, the unique RNA marker can be an mRNA marker, an siRNA marker, or a ribosomal RNA marker.
The primary structure of major rRNA subunit 16S comprise a particular combination of conserved, variable, and hypervariable regions that evolve at different rates and enable the resolution of both very ancient lineages such as domains, and more modern lineages such as genera. The secondary structure of the 16S subunit include approximately 50 helices which result in base pairing of about 67% of the residues. These highly conserved secondary structural features are of great functional importance and can be used to ensure positional homology in multiple sequence alignments and phylogenetic analysis. Over the previous few decades, the 16S rRNA gene has become the most sequenced taxonomic marker and is the cornerstone for the current systematic classification of bacteria and archaea (Yarza et al. 2014. Nature Rev. Micro. 12:635-45).
In some embodiments, a sequence identity of 94.5% or lower for two 16S rRNA genes is strong evidence for distinct genera, 86.5% or lower is strong evidence for distinct families, 82% or lower is strong evidence for distinct orders, 78.5% is strong evidence for distinct classes, and 75% or lower is strong evidence for distinct phyla. The comparative analysis of 16S rRNA gene sequences enables the establishment of taxonomic thresholds that are useful not only for the classification of cultured microorganisms but also for the classification of the many environmental sequences. Yarza et al. 2014. Nature Rev. Micro. 12:635-45).
Exemplary isolated microbes for use according to the present disclosure are provided below in Table 2. Designation of a strain with the Ascus identifier followed by a letter (e.g., AscusEQ_4A, AscusEQ_4B, AscusEQ_4C, etc.) indicates that these strains are variants of the parental strain with the corresponding Ascus identifier. For example, AscusEQ_4A, AscusEQ_4B, Ascusa) 4C, etc. are all variants of the AscusEQ_4 parental strain. Each variant strain shares at least 97% sequence identity with the parental strain.

Moisture content is a measurement of the total amount of water in a composition, usually expressed as a percentage of the total weight. The moisture content is a usefull measurement for determining the dry weight of a composition, and it can be used to confirm whether the desiccation/drying process of a composition is complete. The moisture content is calculated by dividing the (wet weight of the composition minus the weight after desiccating/drying) by the wet weight of the composition, and multiplying by 100.
Moisture content defines the amount of water in a composition, but water activity explains how the water in the composition will react with microorganisms. The greater the water activity, the faster microorganisms are able to grow. Water activity is calculated by finding the ratio of the vapor pressure in a composition to the vapor pressure of pure water. More specifically, the water activity is the partial vapor pressure of water in a composition divided by the standard state partial vapor pressure of pure water. Pure distilled water has a water activity of 1. A determination of water activity of a composition is not the amount of water in a composition, rather it is the amount of excess amount of water that is available for microorganisms to use. Microorganisms have a minimal and optimal water activity for growth.
In some embodiments, the microbial compositions of the present disclosure are desiccated. A microbial composition is desiccated if the moisture content of the composition is between 0% and 20%.

In some embodiments, the microbes or microbial compositions of the disclosure are encapsulated in an encapsulating composition. An encapsulating composition protects the microbes from external stressors prior to entering the gastrointestinal tract of equines, In some embodiments, external stressors include thermal, desiccating, and physical stressors associated with pelleting and extrusion. In some embodiments, external stressors include chemicals present in the compositions to which Encapsulating compositions further create an environment that may be beneficial to the microbes, such as minimizing the oxidative stresses of an aerobic environment on anaerobic microbes, preserving the viability of the microbes wherein vegetative cells or spores form during the pelleting/extrusion process, etc., See Kalsta et al. (U.S. Pat. No. 5,104,662A), Ford (U.S. Pat. No. 5,733,568A), and 1Mosbach and Nilsson (U.S. Pat. No. 4,647,536A) for encapsulation compositions of microbes, and methods of encapsulating microbes.
In one embodiment, the compositions of the present disclosure exhibit a thermal tolerance, which is used interchangeably with heat tolerance and heat resistance. In one embodiment, thermal tolerant compositions of the present disclosure are tolerant of the high temperatures associated with feed manufacturing, mixing of feed and compositions of the present disclosure, storage in high heat environments, etc. In one embodiment, thermal tolerant compositions of the present disclosure are resistant to heat-killing and denaturation of the cell wall components and the intracellular environment. In one embodiment, the compositions of the present disclosure is tolerant or resistant to dessication/water loss.
In one embodiments, the encapsulation is a reservoir-type encapsulation. In one embodiment, the encapsulation is a matrix-type encapsulation. In one embodiment, the encapsulation is a coated matrix-type encapsulation. Burgain et al. (2011. J. Food Eng. 104:467-483) discloses numerous encapsulation embodiments and techniques, all of which are incorporated by reference.
In some embodiments, the compositions of the present disclosure are encapsulated in one or more of the following: gellan gum, xanthan gum, K-Carrageenan, cellulose acetate phthalate, chitosan, starch, milk fat, whey protein, Ca-alginate, raftilose, raftiline, pectin, saccharide, glucose, maltodextrin, gum arabic, guar, seed flour, alginate, dextrins, dextrans, celluloase, gelatin, gelatin, albumin, casein, gluten, acacia gum, tragacanth, wax, paraffin, stearic acid, monodiglycerides, and diglycerides.

In some embodiments, the encapsulation of the compositions of the present disclosure is carried out by an extrusion, emulsification, coating, agglomeration, lyophilization, vacuum-drying, or spray-drying,
In one embodiment, the encapsulating composition comprises microcapsules having a multiplicity of liquid cores encapsulated in a solid shell material. For purposes of the disclosure, a “multiplicity” of cores is defined as two or more.
A first category of useful fusible shell materials is that of normally solid fats, including fats which are already of suitable hardness and animal or vegetable fats and oils which are hydrogenated until their melting points are sufficiently high to serve the purposes of the present disclosure. Depending on the desired process and storage temperatures and the specific material selected, a particular fat can be either a normally solid or normally liquid material. The terms “normally solid” and “normally liquid” as used herein refer to the state of a material at desired temperatures for storing the resulting microcapsules. Since fats and hydrogenated oils do not, strictly speaking, have melting points, the term “melting point” is used herein to describe the minimum temperature at which the fusible material becomes sufficiently softened or liquid to be successfully emulsified and spray cooled, thus roughly corresponding to the maximum temperature at which the shell material has sufficient integrity to prevent release of the choline cores. “Melting point” is similarly defined herein for other materials which do not have a sharp melting point.
Specific examples of fats and oils useful herein (some of which require hardening) are as follows: animal oils and fats, such as beef tallow, mutton tallow, lamb tallow, lard or pork fat, fish oil, and sperm oil; vegetable oils, such as canola oil, cottonseed oil, peanut oil, corn oil, olive oil, soybean oil, sunflower oil, safflower oil, coconut oil, palm oil, linseed oil, tung oil, and castor oil; fatty acid monoglycerides and diglycerides; free fatty acids, such as stearic acid, palmitic acid, and oleic acid; and mixtures thereof. The above listing of oils and fats is not meant to be exhaustive, but only exemplary.
Specific examples of fatty acids include linoleic acid, y-linoleic acid, dihomo-y-linolenic acid, arachidonic acid, docosatetraenoic acid. vaccenic acid, nervonic acid, mead acid, erucic acid, gondoic acid, elaidic acid, oleic acid, palitoleic acid, stearidonic acid, eicosapentaenoic acid, valeric acid, caproic acid, enanthic acid, caprylic acid, pelargonic acid, capric acid, undecylic acid, lauric acid, tridecylic acid, myristic acid, pentadecylic acid, palmitic acid, margaric acid, stearic acid, nonadecyclic acid, arachidic acid, heneicosylic acid, behenic acid, tricosylic acid, lignoceric acid, pentacosylic acid, cerotic acid, heptacosylic acid, montanic acid, nonacosylic acid, melissic acid, henatriacontylic acid, lacceroic acid, psyllic acid, geddic acid, ceroplastic acid, hexatriacontylic acid, heptatriacontanoic acid, and octa.triacontanoic acid.
Another category of fusible materials useful as encapsulating shell materials is that of waxes. Representative waxes contemplated for use herein are as follows: animal waxes, such as beeswax, lanolin, shell wax, and Chinese insect wax; vegetable waxes, such as carnauba., candelilla, bayberry, and sugar cane; mineral waxes, such as paraffin, microcrystalline petroleum, ozocerite, ceresin, and montan; synthetic waxes, such as low molecular weight polyolefin (e.g., CARBOWAX), and polyol ether-esters (e.g., sorbitol); Fischer-Tropsch process synthetic waxes; and mixtures thereof. Water-soluble waxes, such as CARBOWAX and sorbitol, are not contemplated herein if the core is aqueous.
Still other fusible compounds useful herein are fusible natural resins, such as rosin, balsam, shellac, and mixtures thereof.
Various adjunct materials are contemplated for incorporation in fusible materials according to the present disclosure. For example, antioxidants, light stabilizers, dyes and lakes, flavors, essential oils, anti-caking agents, fillers, pH stabilizers, sugars (monosaccharides, disaccharides, trisaccharides, and polysaccharides) and the like can be incorporated in the fusible material in amounts which do not diminish its utility for the present disclosure.
The core material contemplated herein constitutes from about 0.1% to about 50%, about 1% to about 35%. or about 5% to about 30% by weight of the microcapsules. In some embodiments, the core material contemplated herein constitutes no more than about 30% by weight of the microcapsules. In some embodiments, the core material contemplated herein constitutes about 5% by weight of the microcapsules. The core material is contemplated as either a liquid or solid at contemplated storage temperatures of the microcapsules.
The cores may include other additives well-known in the pharmaceutical art, including edible sugars, such as sucrose, glucose, maltose, fructose, lactose, cellobiose, monosaccharides, disaccharides, trisaccharides, and polysaccharides, and mixtures thereof; artificial sweeteners, such as aspartame, saccharin, cyclamate salts, and mixtures thereof; edible acids, such as acetic acid (vinegar), citric acid, ascorbic acid, tartaric acid, and mixtures thereof; edible starches, such as corn starch; hydrolyzed vegetable protein; water-soluble vitamins, such as Vitamin C; water-soluble medicaments; water-soluble nutritional materials, such as ferrous sulfate; flavors; salts; monosodium glutamate; antimicrobial agents, such as sorbic acid; antimycotic agents, such as potassium sorbate, sorbic acid, sodium benzoate, and benzoic acid; food grade pigments and dyes; and mixtures thereof. Other potentially useful supplemental core materials will be apparent to those of ordinary skill in the art.
Emulsifying agents may be employed to assist in the formation of stable emulsions. Representative emulsifying agents include glyceryl monostearate, polysorbate esters, ethoxylated mono- and diglycerides, and mixtures thereof.
For ease of processing, and particularly to enable the successful formation of a reasonably stable emulsion, the viscosities of the core material and the shell material should be similar at the temperature at which the emulsion is formed. In particular, the ratio of the viscosity of the shell to the viscosity of the core, expressed in centipoise or comparable units, and both measured at the temperature of the emulsion, should be from about 22:1 to about 1:1, desirably from about 8:1 to about 1:1, and preferably from about 3:1 to about 1:1. A ratio of 1:1 would be ideal, but a viscosity ratio within the recited ranges is useful.
Encapsulating compositions are not limited to microcapsule compositions as disclosed above. In some embodiments encapsulating compositions encapsulate the microbial compositions in an adhesive polymer that can be natural or synthetic without toxic effect. In some embodiments, the encapsulating composition may be a matrix selected from sugar matrix, gelatin matrix, polymer matrix, silica matrix, starch matrix, foam matrix, glass/glassy matrix etc. See Pirzio et al. (U.S. Pat. No. 7,488,503). In some embodiments, the encapsulating composition may be selected from polyvinyl acetates; polyvinyl acetate copolymers; ethylene vinyl acetate (EVA) copolymers; polyvinyl alcohols; polyvinyl alcohol copolymers; celluloses, including ethylcelluloses, methylcelluloses, hydroxymethylcelluloses, hydroxypropylcelluloses and carboxymethylcellulose; polyvinylpyrolidones; polysaccharides, including starch, modified starch, dextrins, maltodextrins, alginate and chitosans; monosaccharides; fats; fatty acids, including oils; proteins, including gelatin and zeins; gum arabics; shellacs; vinylidene chloride and vinylidene chloride copolymers; calcium lignosulfonates; acrylic copolymers; polyvinylacrylates; polyethylene oxide; acrylamide polymers and copolymers; polyhydroxyethyl acrylate, methylacrylamide monomers; and polychloroprene.

In some embodiments, the matrix comprises a monosaccharide or a disaccharide. In some embodiments, the disaccharide may be selected from sucrose, maltose, lactose, lactulose, trehalose, cellobiose, and chitobiose. In some embodiments, the polysaccharides, saccharides, and/or sugar alcohols are added to the microbial composition or a subcomponent thereof exogenously. In some embodiments, the matrix is an amorphous matrix. In some embodiments, the microbial composition or a subcompenent thereof is vitrified. In some embodiments, the microbial composition or a subcompenent thereof is desiccated. In some embodiments, the microbial composition or a subcompenent thereof is lyophilized. In some embodiments, the microbial composition or a subcompenent thereof is spray dried. In some embodiments, the microbial composition or a subcompenent thereof is spray congealed. In some embodiments, the microbial composition is preserved/stabilized by preservation by vaporization. See Harel and Kohavi-Beck (U.S. Patent Application No. 8,097,245). See Bronshtein (U.S. Pat. No. 9,469,835).

In some embodiments, the encapsulating compositions comprise at least 1, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 11, at least 12, at least 13, at least 14, at least 15, at least 16, at least 17, at least 18, at least 19, or at least 20 layers of encapsulation/encapsulants.
In some embodiments, the encapsulating compositions comprise at least two layers of encapsulation. In some embodiments, each layer of encapsulation confers a different characteristic to the composition. In some embodiments, no two consecutive layers confer the same characteristic. In some embodiments, at least one layer of the at least two layers of encapsulation confers thermostability, shelf stability, ultraviolet resistance, moisture resistance, dessication resistance, hydrophobicity, hydrophilic.*, lipophobicity, lipophilicity, pH stability, acid resistance, and base resistance.
In some embodiments, the encapsulating compositions comprise two layers of encapsulation; the first layer confers thermostability and/or shelf stability, and the second layer provides pH resistance.
In some embodiments, the encapsulating layers confer a timed release of the microbial composition held in the center of the encapsulating layers. In some embodiments, the greater the number of layers confers a greater amount of time before the microbial composition is exposed, post administration.

Methods of Determining Microbial Abundance and Co-Occurrence qf Microorganisms with Environmental Parameters
According to the methods provided herein, a sample is processed to detect the presence of one or more microorganism types in the sample (
In one embodiment, the sample, or a portion thereof is subjected to flow cytometry (FC) analysis to detect the presence and/or number of one or more microorganism types (
In one embodiment, a sample is stained with one or more fluorescent dyes wherein a fluorescent dye is specific to a particular microorganism type, to enable detection via a flow cytometer or some other detection and quantification method that harnesses fluorescence, such as fluorescence microscopy. The method can provide quantification of the number of cells and/or cell volume of a given organism type in a sample. In a further embodiment, as described herein, flow cytometry is harnessed to determine the presence and quantity of a unique first marker and/or unique second marker of the organism type, such as enzyme expression, cell surface protein expression, etc. Two- or three-variable histograms or contour plots of, for example, light scattering versus fluorescence from a cell membrane stain (versus fluorescence from a protein stain or DNA stain) may also be generated, and thus an impression may be gained of the distribution of a variety of properties of interest among the cells in the population as a whole. A number of displays of such multiparameter flow cytometric data are in common use and are amenable for use with the methods described herein.
In one embodiment of processing the sample to detect the presence and number of one or more microorganism types, a microscopy assay is employed (
In another embodiment of in order to detect the presence and number of one or more microorganism types, the sample, or a portion thereof is subjected to fluorescence microscopy. Different fluorescent dyes can be used to directly stain cells in samples and to quantify total cell counts using an epifluorescence microscope as well as flow cytometry, described above. Useful dyes to quantify microorganisms include but are not limited to acridine orange (AO), 4,6-di-amino-2 phenylindole (DAPI) and 5-cyano-2,3 Dytolyl Tetrazolium Chloride (CTC). Viable cells can be estimated by a viability staining method such as the LIVE/DEAW Bacterial Viability Kit (Bac-LightTM) which contains two nucleic acid stains: the green-fluorescent SYTO 9Tm dye penetrates all membranes and the red-fluorescent propidium iodide (PI) dye penetrates cells with damaged membranes. Therefore, cells with compromised membranes will stain red, whereas cells with undamaged membranes will stain green. Fluorescent in situ hybridization (FISH) extends epifluorescence microscopy, allowing fbr the fast detection and enumeration of specific organisms. FISH uses fluorescent labelled oligonucleotides probes (usually 15-25 basepairs) which bind specifically to organism DNA in the sample, allowing the visualization of the cells using an epifluorescence or confocal laser scanning microscope (CLSM). Catalyzed reporter deposition fluorescence in situ hybridization (CARD-FISH) improves upon the FISH method by using oligonucleotide probes labelled with a horse radish peroxidase (HRP) to amplify the intensity of the signal obtained from the microorganisms being studied. FISH can be combined with other techniques to characterize microorganism communities. One combined technique is high affinity peptide nucleic acid (PNA)-FISH, where the probe has an enhanced capability to penetrate through the Extracellular Polymeric Substance (EPS) matrix. Another example is LIVE/DEAD-FISH which combines the cell viability kit with FISH and has been used to assess the efficiency of disinfection in drinking water distribution systems.
In another embodiment, the sample, or a portion thereof is subjected to Raman micro-spectroscopy in order to determine the presence of a microorganism type and the absolute number of at least one microorganism type (
In yet another embodiment, the sample, or a portion thereof is subjected to centrifugation in order to determine the presence of a microorganism type and the number of at least one microorganism type (
In another embodiment, the sample, or a portion thereof is subjected to staining in order to determine the presence of a microorganism type and the number of at least one microorganism type (
In another embodiment, the sample, or a portion thereof is subjected to mass spectrometry (MS) in order to determine the presence of a microorganism type and the number of at least one microorganism type (
In another embodiment, the sample, or a portion thereof is subjected to lipid analysis in order to determine the presence of a microorganism type and the number of at least one microorganism type (
In the aspects of the methods provided herein, the number of unique first makers in the sample, or portion thereof (e.g., sample aliquot) is measured, as well as the abundance of each of the unique first markers (
Any marker that is unique to an organism strain can be employed herein. For example, markers can include, but are not limited to, small subunit ribosomal RNA genes (16S/18S rDNA), large subunit ribosomal RNA genes (23S/25S/28S rDNA), intercalary 5.8S gene, cytochrome c oxidase, beta-tubulin, elongation factor, RNA polymerase, and internal transcribed spacer (ITS).
Ribosomal RNA genes (rDNA), especially the small subunit ribosomal RNA genes, i.e., 185 rRNA genes (18S rDNA) in the case of eukaryotes and 165 rRNA (16S iDNA) in the case of prokaryotes, have been the predominant target for the assessment of organism types and strains in a microbial community. However, the large subunit ribosomal RNA genes, 28S rDNAs, have been also targeted. rDNAs are suitable for taxonomic identification because: (i) they are ubiquitous in all known organisms; (ii) they possess both conserved and variable regions; (iii) there is an exponentially expanding database of their sequences available for comparison. In community analysis of samples, the conserved regions serve as annealing sites for the corresponding universal PCR and/or sequencing primers, whereas the variable regions can be used for phylogenetic differentiation. In addition, the high copy number of rDNA in the cells facilitates detection from environmental samples.
The internal transcribed spacer (ITS), located between the 18S rDNA and 28S rDNA, has also been targeted. The ITS is transcribed but spliced away before assembly of the ribosomes The ITS region is composed of two highly variable spacers, ITSI and ITS2, and the intercalary 5.8S gene. This rDNA operon occurs in multiple copies in genomes. Because the ITS region does not code for ribosome components, it is highly variable.
In one embodiment, the unique RNA marker can be an mRNA marker, an siRNA marker or a ribosomal RNA marker.
Protein-coding functional genes can also be used herein as a unique first marker. Such markers include but are not limited to: the recombinase A gene family (bacterial RecA, archaea RadA. and RadB, eukaryotic Rad51. and Rad57, phage tivsX); RNA polymerase subunit (−RpoB) gene, which is responsible for transcription initiation and elongation; chaperonins. Candidate marker genes have also been identified for bacteria plus archaea: ribosomal protein S2 (rpsB), ribosomal protein S10 (rpsJ), ribosomal protein L1 (rplA), translation elongation factor EF-2, translation initiation factor IF-2, metalloendopeptidase, ribosomal protein L22, ffh signal recognition particle protein, ribosomal protein L4./Lle (rplD), ribosomal protein L2 (rp113), ribosomal protein S9 (rpsl), ribosomal protein L3 (rp1C), phenylalanyl-tRNA synthetase beta subunit, ribosomal protein L14b123e (rplN), ribosomal protein S5, ribosomal protein S19 (rpsS), ribosomal protein S7, ribosomal protein L16/L10E (rplP), ribosomal protein S13 (rpsM), phenylalanyl-tRNA synthetase a subunit, ribosomal protein LIS, ribosomal protein L25/L23, ribosomal protein L6 (rp1F), ribosomal protein L11 (rplK), ribosomal. protein L5 (rplE), ribosomal protein S12/S23, ribosomal protein L29, ribosomal protein S3 (rpsC), ribosomal protein Si I (rpsK), ribosomal protein L10, ribosomal protein S8, tRNA pseudouridine synthase B, ribosomal protein L18P/L5E, ribosomal protein S1SP/S13e, Porphobilinogen deaminase, ribosomal protein S17, ribosomal protein L13 (rp1M), phosphoribosylformylglycina.midine cyclo-ligase (rpsE), ribonuclease tiff and ribosomal protein L24. Other candidate marker genes for bacteria include: transcription elongation protein NusA (nus;), rpoB DNA-directed RNA polymerase subunit beta (rpoB), GTP-binding protein EngA, rpoC DNA-directed RNA polymerase subunit beta', priA primosome assembly protein, transcription-repair coupling factor. CTP synthase (pyrG), secY preprotein translocase subunit SecY, GTP-binding protein Obg/CgtA, DNA polymerase I, rpsF 30S ribosomal protein S6, poA DNA-directed RNA polymerase subunit alpha, peptide chain release factor 1, rp1I 50S ribosomal protein L9, polyribonucleotide nucleotidyltransferase, tsf elongation factor Ts (tsf), rplQ 50S ribosomal protein L17, tRNA (guanine-N(1)-)-methyltransferase (rpIS), rplY probable 50S ribosomal protein L25, DNA repair protein RadA, glucose-inhibited division protein A, ribosome-binding factor A, DNA mismatch repair protein MutL, smpB SsrA-binding protein (smpB), N-acetylglucosaminyl transferase, S-adenosyl-methyltransferase IsdraW, UDP-N-acetylmuramoylalanine-D-glutamate ligase, rp1S 50S ribosomal protein L19, rp1T 50S ribosomal protein L20 (rp1T), ruvA Holliday junction DNA helicase, ruvB Holliday junction DNA helicase B, serS seryl-tRNA synthetase, rplU 50S ribosomal protein L21, rpsR 30S ribosomal protein S18, DNA mismatch repair protein MutS, rpsT 30S ribosomal protein S20, DNA repair protein RecN, frr ribosome recycling factor (frr), recombination protein RecR, protein of unknown function UPF0054, miaA tRNA isopentenyltransferase, GTP-binding protein YchF, chromosomal replication initiator protein DnaA, dephospho-CoA kinase, 16S rRNA processing protein RimM, ATP-cone domain protein, 1-deoxy-D-xylulose 5-phosphate reductoisomerase, 2C-methyl-D-erythritol 2,4-cyclodiphosphate synthase, fatty acid/phospholipid synthesis protein PlsX, tRNA(Ile)-lysidine synthetase, dnaG DNA primase (dnaG), ruvC Holliday junction resolvase, rpsP 30S ribosomal protein S16, Recombinase A recA, riboflavin biosynthesis protein RibF, glycyl-tRNA synthetase beta subunit, trmU tRNA (5-methylaminomethyl-2-thiouridylate)-methyltransferase, rpmI 50S ribosomal protein L35, hemE uroporphyrinogen decarboxylase, Rod shape-determining protein, rpmA 50S ribosomal protein L27 (rpmA), peptidyl-tRNA hydrolase, translation initiation factor IF-3 (infC), LTDP-N-acetylmuramyl-tripeptide synthetase, rpmF 50S ribosomal protein L32, rpIL 50S ribosomal protein L7/L12 (rpIL:), leuS leucyl-tRNA synthetase, ligA NAD-dependent DNA ligase, cell division protein FtsA, GTP-binding protein TypA, ATP-dependent Clp protease, A IP-binding subunit ClpX, DNA replication and repair protein RecF and UDP-N-acetylenolpyruvoylglucosamine reductase.
Phospholipid fatty acids (PLFAs) may also be used as unique first markers according to the methods described herein. Because PLFAs are rapidly synthesized during microbial growth, are not found in storage molecules and degrade rapidly during cell death, it provides an accurate census of the current living community. All cells contain fatty acids (FAs) that can be extracted and esterified to form fatty acid methyl esters (FAMEs). When the FAMEs are analyzed using gas chromatography-mass spectrometry, the resulting profile constitutes a ‘fingerprint’ of the microorganisms in the sample. The chemical compositions of membranes for organisms in the domains Bacteria and Eukarya are comprised of fatty acids linked to the glycerol by an ester-type bond (phospholipid fatty acids (PLFAs)). In contrast, the membrane lipids of Archaea are composed of long and branched hydrocarbons that are joined to glycerol by an ether-type bond (phospholipid ether lipids (PLELs)). This is one of the most widely used non-genetic criteria to distinguish the three domains. In this context, the phospholipids derived from microbial cell membranes, characterized by different acyl chains, are excellent signature molecules, because such lipid structural diversity can be linked to specific microbial taxa.
As provided herein, in order to determine whether an organism strain is active, the level of expression of one or more unique second markers, which can be the same or different as the first marker, is measured (
In one embodiment, if the level of expression of the second marker is above a threshold level (e.g., a control level) or at a threshold level, the microorganism is considered to be active (
Second unique markers are measured, in one embodiment, at the protein, RNA or metabolite level. A unique second marker is the same or different as the first unique marker.
As provided above, a number of unique first markers and unique second markers can be detected according to the methods described herein. Moreover, the detection and quantification of a unique first marker is carried out according to methods known to those of ordinary skill in the art (
Nucleic acid sequencing (e.g., gDNA, cDNA, rRNA, mRNA) in one embodiment is used to determine absolute abundance of a unique first marker and/or unique second marker. Sequencing platforms include, but are not limited to, Sanger sequencing and high-throughput sequencing methods available from Roche/454 Life Sciences, Illumina/Solexa, Pacific Biosciences, Ion Torrent and Nanopore. The sequencing can be ampl icon sequencing of particular DNA or RNA sequences or whole metagenome/transcriptome shotgun sequencing.
Traditional Sanger sequencing (Sanger et al. (1977) DNA sequencing with chain-terminating inhibitors. Proc Natl. Acad. Sci. USA, 74, pp. 5463-5467, incorporated by reference herein in its entirety) relies on the selective incorporation of chain-terminating dideoxynucleotides by DNA polymerase during in vitro DNA replication and is amenable for use with the methods described herein.
In another embodiment, the sample, or a portion thereof is subjected to extraction of nucleic acids, amplification of DNA of interest (such as the rRNA gene) with suitable primers and the construction of clone libraries using sequencing vectors. Selected clones are then sequenced by Sanger sequencing and the nucleotide sequence of the DNA of interest is retrieved, allowing calculation of the number of unique microorganism strains in a sample.
454 pyrosequencing from Roche/454 Life Sciences yields long reads and can be harnessed in the methods described herein (Margulies et al. (2005) Nature, 437, pp. 376-380; U.S. Pat. Nos. 6,274,320; 6,258,568; 6,210,891, each of which is herein incorporated in its entirety for all purposes). Nucleic acid to be sequenced (e.g., amplicons or nebulized genomic/metagenomic DNA) have specific adapters affixed on either end by PCR or by ligation. The DNA with adapters is fixed to tiny beads (ideally, one bead will have one DNA fragment) that are suspended in a water-in-oil emulsion. An emulsion PCR step is then performed to make multiple copies of each DNA fragment, resulting in a set of beads in which each bead contains many cloned copies of the same DNA fragment. Each bead is then placed into a well of a fiber-optic chip that also contains enzymes necessary for the sequencing-by-synthesis reactions. The addition of bases (such as A, C, G, or T) trigger pyrophosphate release, which produces flashes of light that are recorded to infer the sequence of the DNA fragments in each well. About 1 million reads per run with reads up to 1,000 bases in length can be achieved. Paired-end sequencing can be done, which produces pairs of reads, each of which begins at one end of a given DNA fragment. A molecular barcode can be created and placed between the adapter sequence and the sequence of interest in multiplex reactions, allowing each sequence to be assigned to a sample bioinfortnatically.
Illumina/Solexa sequencing produces average read lengths of about 25 basepairs (bp) to about 300 bp (Bennett et al. (2005) Phartnacogenomics, 6:373-382; Lange et al. (2014). BMC Genomics 15, p. 63; Fadrosh et al. (2014) Microbiotne 2, p. 6; Caporaso et al. (2012) ISME J, 6, p. 1621-1624; Bentley et al. (2008) Accurate whole human genome sequencing using reversible terminator chemistry. Nature, 456:53-59). This sequencing technology is also sequencing-by-synthesis but employs reversible dye terminators and a flow cell with a field of oligos attached. DNA fragments to be sequenced have specific adapters on either end and are washed over a flow cell filled with specific oligonucleotides that hybridize to the ends of the fragments. Each fragment is then replicated to make a cluster of identical fragments. Reversible dye-terminator nucleotides are then washed over the flow cell and given time to attach. The excess nucleotides are washed away, the flow cell is imaged, and the reversible terminators can be removed so that the process can repeat and nucleotides can continue to be added in subsequent cycles. Paired-end reads that are 300 bases in length each can be achieved. An Illumina platform can produce 4 billion fragments in a paired-end fashion with 125 bases for each read in a single run. Barcodes can also be used for sample multiplexing, but indexing primers are used.
The SOLiD (Sequencing by Oligonucleotide Ligation and Detection, Life Technologies) process is a “sequencing-by-ligation” approach, and can be used with the methods described herein for detecting the presence and abundance of a first marker and/or a second marker (
The Ion Torrent system, like 454 sequencing, is amenable for use with the methods described herein for detecting the presence and abundance of a first marker and/or a second marker (

In another embodiment, fragment length polymorphism (RFLP) of PCR-amplified rDNA fragments, otherwise known as amplified ribosomal DNA restriction analysis (ARDRA), is used to characterize unique first markers and the abundance of the same in samples (
One fingerprinting technique used in detecting the presence and abundance of a unique first marker is single-stranded-conformation polymorphism (SSCP) (Lee et al. (1996). Appl Environ Microbiol 62, pp. 3112-3120; Scheinert et al. (1996). J. Microbiol. Methods 26, pp. 103-117; Schwieger and Tebbe (1998). Appl. Environ. Microbiol. 64, pp. 4870-4876, each of which is incorporated by reference herein in its entirety). In this technique, DNA fragments such as PCR products obtained with primers specific for the 16S rRNA gene, are denatured and directly electrophoresed on a non-denaturing gel. Separation is based on differences in size and in the folded conformation of single-stranded DNA, which influences the electrophoretic mobility. Reannealing of DNA strands during electrophoresis can be prevented by a number of strategies, including the use of one phosphorylated primer in the PCR followed by specific digestion of the phosphorylated strands with lambda exonuclease and the use of one biotinylated primer to perform magnetic separation of one single strand after denaturation. To assess the identity of the predominant populations in a. given bioensetnble, in one embodiment, bands are excised and sequenced, or SSCP-patterns can be hybridized with specific probes. Electrophoretic conditions, such as gel matrix, temperature, and addition of glycerol to the gel, can influence the separation.

The environmental parameter can be a parameter of the sample itself, e.g., pH, temperature, amount of protein in the sample. Alternatively, the environmental parameter is a parameter that affects a change in the identity of a microbial community (i.e., where the “identity” of a microbial community is characterized by the type of microorganism strains and/or number of particular microorganism strains in a community), or is affected by a change in the identity of a microbial community. For example, in some embodiments, an environmental parameter is the food intake of an animal or the amount of eggs produced. In some embodiments, the environmental parameter is the presence, activity and/or abundance of a second microorganism strain in the microbial community, present in the same sample. In some embodiments, an environmental parameter is referred to as a metadata parameter.
Other examples of metadata parameters include but are not limited to genetic information from the host from which the sample was obtained (e.g., DNA mutation information), sample pH, sample temperature, expression of a particular protein or snRNA, nutrient conditions (e.g., level and/or identity of one or more nutrients) of the surrounding environment/ecosystem , susceptibility or resistance to disease, onset or progression of disease, susceptibility or resistance of the sample to toxins, efficacy of xenobiotic compounds (pharmaceutical drugs), biosynthesis of natural products, or a combination thereof
The term maximal information coefficient or “MIC” refers to a type of nonparatnetric analysis that identifies a score between active microbial strains of the present disclosure and at least one measured metadata (e.g., increase in weight). The results from the nonparametric analysis are pooled to create a list of all relationships and their corresponding MIC scores. If the relationship scores below a given threshold, the relationship is deemed/identified as irrelevant. If the relationship is above a given threshold, the relationship deemed/identified as relevant, and is further subject to network analysis. Methods of determining MIC scores are further described in U.S. Pat. No. 9,540,676, which is hereby incorporated by reference in its entirety.
The following code fragment shows an exemplary methodology for MIC analysis, according to one embodiment:
With regard to MIC scores, a cut-off based on this score is used to define useful and non-useful microorganisms with respect to the improvement of specific traits. The point at which the data points on the curve move transition from the log scale to the linear scale (with regard to the slope) is the inflection point. The organisms with MIC scores that fall below the inflection point are generally non-useful, while the organisms with MIC scores that are found above the inflection point are generally useful, as it pertains to the specific characteristic being evaluated for the MIC score.
In some embodiments, the compositions of the present disclosure comprise one or more bacteria that have a MIC score of at leak about 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.7, 0.75, 0.8, 0.85, 0.9, or 0.95. In some embodiments, the isolated bacteria selected for inclusion in the microbial compositions described herein comprise a MIC score of at least 0.2.
Based on the output of the network analysis, active strains are selected for preparing products (e.g., ensembles, aggregates, and/or other synthetic groupings) containing the selected strains. The output of the network analysis can also be used to inform the selection of strains for further product composition testing. Thresholds can be, depending on the implementation and application: (1) empirically determined (e.g., based on distribution levels, setting a cutoff at a number that removes a specified or significant portion of low level reads); (2) any non-zero value; (3) percentage/percentile based; (4) only strains whose normalized second marker (i.e., activity) reads is greater than normalized first marker (cell count) reads; (5) log2 fold change between activity and quantity or cell count; (6) normalized second marker (activity) reads is greater than mean second marker (activity) reads for entire sample (and/or sample set); and/or any magnitude threshold described above in addition to a statistical threshold (i.e., significance testing). The following example provides thresholding detail for distributions of RNA-based second marker measurements with respect to DNA-based first marker measurements, according to one embodiment.
The isolation, identification, and culturing of the microbes of the present disclosure can be effected using standard microbiological techniques. Examples of such techniques may be found in Gerhardt, P. (ed.) Methods for General and Molecular Microbiology. American Society for Microbiology, Washington, D.C. (1994) and Lennette, E. H. (ed.) Manual of Clinical Microbiology, Third Edition. American Society for Microbiology, Washington, D.C. (1980), each of which is incorporated by reference.
Isolation can be effected by streaking the specimen on a solid medium (e.g., nutrient agar plates) to obtain a single colony, which is characterized by the phenotypic traits described hereinabove (e.g., Gram positive/negative, capable of forming spores aerobically/anaerobically, cellular morphology, carbon source metabolism, acid/base production, enzyme secretion, metabolic secretions, etc.) and to reduce the likelihood of working with a culture which has become contaminated.
For example, for microbes of the disclosure, biologically pure isolates can be obtained through repeated subculture of biological samples, each subculture followed by streaking onto solid media to obtain individual colonies or colony forming units. Methods of preparing, thawing, and growing lyophilized bacteria are commonly known, for example, Gherna, R. L. and C. A. Reddy. 2007. Culture Preservation, p 1019-1033. In C. A. Reddy, T. J.

The present disclosure is further illustrated by reference to the following Experimental Data and Examples. However, it should be noted that these Experimental Data and Examples, like the embodiments described above, are illustrative and are not to be construed as restricting the scope of the disclosure in any way.
An equine microbial composition (comprising AscusEQ_4F (SEQ ID NO: 10, AscusEQ_61A (SEQ ID NO: 320), AscusEQ_140A (SEQ ID NO: 142), AscusEQ_414G SEQ ID NO: 433), and AscusEQ109A (SEQ ID NO: 476), referred to as Ascus Equine) was formulated for administration to equines. Briefly, the equine product is administered as a sweet paste delivered orally. The dose therefore needs high viscosity to delay oxygen permeation during administration and to provide time for the equine patient to consume the majority of the dose without loss of composition. Sodium alginate encapsulation of microbes was used to assist in delivery to hindgut by protecting cells against variable pH/low pH within equine gastric contents.
Solidification and sweetening: Gelatin and xantham. gum tested for solidification viscosity at the following concentrations:
(a) Gelatin 0.1%-1.4%
(b) Xantham Gum 0.2%-2.0%
(c) Agar 0.25%-2.5%.
Concentrations of xantham gum higher than 1.4% gelled adequately. Agar concentrations of 1% were ideal. Other potential food grade thickening agents suitable for use during the solidification process include: starches, alginin, guar gum, collagen, pectin, and carboxymethyl cellulose. The solidified mixture is sweetened with corn syrup, molasses, cane molasses, brewer's yeast, and/or honey to be made palatable to horse. Salt (e.g, sodium chloride) also improves palatability.
Solidification/Sweetening carrier solution formulation: The solidification and sweetening agents are mixed together to form a carrier solution comprising water, cane molasses, sodium chloride, and 1.0% agar. A fluid gel carrier solution (Table 7) was created and then immediately post-autoclave, transferred to an anaerobic chamber and allowed to solidify while mixing by stir bar. Once solidified, the media was blended with an autoclaved overhead mixer until the correct liquid consistency is obtained. Using a serological pipet controller, 80 mLs aliquots were aliqu.oted into fluid gel carrier serum bottles.
Microbial solution formulation: The microbial cells are prepared and stored separately. Individual strains are inoculated into anaerobic bottles and grown for 24 hours. Cells are enumerated and centrifuged to remove fermentation broth. Cells are resuspended in PBS and centrifuged to wash cell pellet. Cells are resuspended in a soy peptone/dextrose suspension solution for long term storage at 4° C.
Five equine product strains (AscusEQ_4F (SEQ ID NO: 11), AscusEQ_61A (SEQ ID NO: 320), AseusEQ_—140A (SEQ ID NO: 142), AsousEQ_414G (SEQ ID NO: 433), and AscusEQ_109.A (SEQ ID NO: 476) were inoculated into separate anaerobic tryptic soy broth bottles and incubated anaerobically for 24 hours. After incubation, cell concentrations were enumerated by Petroff-Hausser counting chamber. The appropriate amount of culture was then centrifuged at 4,300×g for 20 minutes at 4° C. Supernatants were decanted and cell pellets washed via resuspension in anaerobic PBS followed by centrifugation at 4,300×g for 20 minutes at 4° C. Supernatants were again decanted and cells resuspended in stability solution (Table 8). Strains were then combined and aliquoted in 20 mL aliquots into microbial solution serum bottles.
Composition Administration: When ready to administer, sanitize the top of the microbial solution serum bottle with an alcohol wipe and withdraw 20 mL using a syringe (20 or 30 mL syringe) and needle (18G). Sanitize the top of the fluid gel carrier bottle and inject the 20 nit, microbial solution into the fluid gel. Mix the two solutions by shaking vigorously for approximately 10 seconds. Remove the aluminum crimp seal and remove the stopper (Contents will be under slight pressure due to the 20 mL microbial solution addition). Remove the plunger from a 50+mL catheter tip syringe and shake 50 mLs of the solution into the syringe. Administer orally by inserting the nozzle of the syringe into the interdental space and depositing the appropriate amount. Table 9 provides the final composition per 50 mL dose.
Experiments were performed to gauge the efficacy of the microbial compositions described herein in reducing recurrent equine colic and to track microbial community changes.
Each horse enrolled in the study received one daily dose of an equine microbial composition (comprising AscusEQ_4F (SEQ ID NO: 11), AscusEQ_61A (SEQ ID NO: 320). AscusEQ_140A (SEQ ID NO: 142), AscusEQ_414G (SEQ ID NO: 433), and AscusEQ_1.09A (SEQ ID NO: 476), referred to as Ascus Equine) for 14 days. Fecal samples were collected daily from enrolled horses during the 14-day administration. Daily fecal sampling continued for 7 days after the final dose of the Ascus Equine microbial composition. An overview of Ascus Equine formulations, storage, and preparation conditions are provided below in Table 10.
Health Observations were performed by a vet throughout the 14-day administration period and on follow-up sampling dates. Additional observations were made if necessary depending on the needs of the patient. If additional colic episodes occur in the 60-day period following administration, additional unscheduled sample(s) were taken when the horse was admitted for colic evaluation.
Seven patients were treated according to the protocol outlined above. The initial health status of the patients is as follows:
(a) Patient # 1: Experienced several episodes of colic in the past. Although not actively colicking at the start of microbe administration, the patient's fecal microbiome revealed that the patient was in a transient colic state, which explains the reoccuring colic episodes.
(b) Patient # 2: Not actively colicking, and did not have frequent colic episodes in the past. Machine learning revealed that the patient was in a healthy state at the onset of microbe administration.
(c) Patient 43: Not actively colicking, and did not have frequent colic episodes in the past. Machine learning revealed that the patient was in a healthy state at the onset of microbe administration.
(d) Patient # 4: Experienced several episodes of colic in the past. Actively colicking at the start of microbe administration.
(e) Patient # 5: Experienced several episodes of colic in the past. Although not actively colicking at the start of microbe administration, the patient's fecal microbiome revealed that the patient was in a transient colic state, which explains the reoccuring colic episodes.
(f) Patient # 6: Not actively colicking, and did have frequent colic episodes in the past. Machine learning revealed that the patient was in a transient, non-colicking/asymptomatic state at the onset of microbe administration.
(g) Patient # 7: Not actively colicking, and did not have frequent colic episodes in the past. Machine learning revealed that the patient was in a transient, non-colicking/asymptomatic state at the onset of microbe administration.
Administration of Ascus Equine to all 7 patients did not cause any abnormal health observations. No colic events were noted during the administration period nor follow up period. The pre-administration fecal microbiomes of the patients were compared to the post-administration fecal microbiome to assess efficacy of native microorganisms in shifting the overall microbial community towards a more healthy state. Previous studies have found that reduced alpha diversity is a common characteristic of healthy microbiomes.
Patients can be loosely categorized into the following groups:
(a) Healthy patients with no history of colic: Patient 2. Patient 3, Patient 7
(b) Healthy patients with a history of colic: Patient 1, Patient 5, Patient 6
(c) Actively colicing patients: Patient 4.
In healthy patients with no history of colic who were not actively colicing, little change was observed in alpha diversity after administration of microorganisms. However, the composition of the microbiome was found to shift even closer to the “healthy” state that is more healthy-associated microbes were observed in their fecale microbiomes. Although these animals were not colicing, the post-administration state of the fecal microbiome was more optimal than the pre-administration state.
In healthy/asymptomatic patients who did have a history of colic, many of the pre-administration samples were found to resemble a more colic-like microbiome. This suggests that the patients were in a transient state, and thus more likely to develop a symptomatic colic episode. After administration of microorganisms, patients' fecal microbiomes generally exhibited a reduction in alpha diversity, suggesting that the post-administration state of the fecal microbiome is more optimal than the pre-administration state. Similarly, the composition of their microbiomes because to have increased abundance of healthy-associated microbes. Patient # 5 did not exhibit a clear decrease in alpha diversity, however, it's possible that the microorganisms needed to be administered for longer than 2 weeks since this particular patient experienced very frequent and very severe colic episodes. The shift in alpha diversity suggests that the microbiome was beginning to change towards the end of the administration period, and potentially needed additional time to fully exert its impact,
Actively colicing patients saw the largest improvement in state. Patient # 4 was experiencing gas colic at the time of administration. After microorganisms were administered, a decrease in alpha diversity was observed, as well as a clear shift in the fecal microbiome towards a more healthy state (healthy-associated microorganisms increased in abundace). No additional colic episodes were observed in the follow-up period. In this case, the post-administration state of the fecal microbiome was more optimal than the pre-administration state. No additional colicing symptoms were observed in the patient, and the patient is likely to have fewer reoccuring cases of colic since the microbiome has been pushed towards a healthier, more stable state.
Collectively, the fecal microbiome data obtained from this case study suggests that administration of Ascus Equine for a 2-week period can shift the microbiome of a horse that experiences frequent colic episodes or a horse that is actively colicing towards a more stable microbiotne that causes fewer/no colic episodes.
