Respiratory disease epidemics have affected human populations throughout the globe in recent history. Severe Acute Respiratory Syndrome (SARS) emerged in China in 2002 and caused 8000 cases with a 10% mortality rate. Middle Eastern Respiratory Syndrome (MERS) MERS emerged in 2012 and caused 1700 cases with almost 40% mortality. Coronaviruses were identified as the infectious agents responsible for the SARS and MERS epidemics. These viruses are genetically diverse and have the ability to move in and out of human and new zoonotic hosts making them a challenge to counteract.
In December 2019, there was an outbreak of acute respiratory disease in Wuhan city, Hubei province, China with patients suffering from unexplainable pneumonia. By 7 Jan. 2020 it was confirmed that this new acute respiratory disease was caused by a novel coronavirus, SARS-CoV-2. Cases of the new disease, COVID-19, quickly throughout China and the world aided by virtue of international travel. On 11 Mar. 2020 The World Health Organisation (WHO) declared the disease as a pandemic.
Patients infected with SARS-CoV-2 may be asymptomatic. However, patients with symptoms may experience fever, dry cough and shortness of breath resulting from infection in the upper respiratory tract. Patients may also display flu-like symptoms. Where the infection is more severe and spread deeply into the lungs more serious illness and difficulty in breathing may develop. Secondary infection and/or non-pulmonary conditions (heart, renal complications) may also develop. Serious illness typically features pneumonia leading to acute respiratory disease syndrome (ARDS), which is one of the major causes of deaths from COVID-19.
There is no established treatment option for ARDS caused by SARS-CoV-2. Instead, supporting care and non-specific treatment protocols have been used to ameliorate patient's symptoms. Lung ventilator strategies either alone or in combination with the administration of, for example, broad spectrum antiviral or antibacterial agents or convalescent plasma remain the mainstay of available options in the absence of effective pharmaceutical therapy.
Further, candidates for pharmaceutical therapy of ARDS may lack the safety and the activity required. For example, steroids should not be generally used as they are known to decrease the immune response and may increase viral shedding. Attempts to treat patients in the prior SARS or MERS epidemics with steroids were not effective as were attempts with approved antivirals (ribavirin, lopinavir-ritonavir) and immunomodulators. Side effects can be observed with the above agents. For example anemia in the case of ribivarin.
More recently dexamethasone, a corticosteroid used in a wide range of conditions for its anti-inflammatory and immunosuppressant effects, has been tested in hospitalized patients with COVID-19 in the United Kingdom's national clinical trial RECOVERY and found to have benefits for critically ill patients. According to preliminary findings shared with WHO, for patients on ventilators, the treatment was shown to reduce mortality by about one third, and for patients requiring only oxygen, mortality was cut by about one fifth.
Although no specific antiviral has been approved, remdesivir has been found to reduce the time to recovery.
Whilst developing effective treatments is desirable, it is preferable that viral infection is prevented. Alternatively that it becomes possible to vaccinate against infection.
Prevention of corona virus infections is generally accomplished by physical means and disinfection. This includes effective handwashing, the use of face masks and shields, gloves and other forms of personal protective equipment. Simple handwashing with soap and water and hand sanitizers is effective to inactivate coronaviruses. Such measures prevent an individual from spreading virus from the hands to the oral or nasal cavities and thus infecting the respiratory system. Additionally, it prevents transmission through contacting other individuals.
Once an individual is infected by coronavirus in the respiratory system, the use of a mask acts to minimise the transmission of virus by the aerosol route. Similarly, a mask worn by an uninfected individual will reduce the probability of infection by inhaling viral containing aerosols.
However, handwashing products are not suitable for use in the oral or nasal cavities which is typically where initial infection occurs.
Thus there continues to exist a clear need for agents that are not only effective in handwashing but are safe and effective in use in the oral and nasal cavities.
More generally viral infections are the cause of serious disease in humans and animals. The development of suitable vaccines and effective treatments remain an important priority, especially where the underlying virus is highly infective.
Some viral families of clinical significance to humans and/or animals are as follows:
SARS-CoV-1

Animal parasitism is responsible for a significant burden on animal welfare, which associated with economic costs spanning the agricultural industry. Three major groups of parasites are generally recognised including; protozoa, helminths and arthropods.
There are a diverse range of protozoan parasites, which are known to cause disease across both vertebrate and invertebrate species. These parasites are the causative agent for diseases including, but not limited to malaria; dysentery, giardia, cryptosporidium, Chaga's disease and coccidiosis.
Whilst some protozoa are specific to one host species, other protozoa are capable of infecting a range of host species. Therefore, the unchecked usage of anti-microbial drugs, particularly throughout the food supply chain is facing growing restrictions. This to ensure that these drugs are effective in emergency situations.
The requirement for non-antibiotic alternatives to help prevent disease developing is therefore an important means to improving global health and welfare outcomes, without destroying economic viability.
Microsporidian parasites are of economic significance in aqueous environments, particularly in prawn and shrimp aquaculture. Enterocytozoon hepatopenaei (EHP) is known to infect only the tubule epithelial cells of the hepatopancreas of prawns. Infection occurs by the extrusion or growth of the polar tubule of the microsporidia allowing it to attach to the hepatopancreas of prawns.
Some prawn species that are particularly susceptible to EHP are Penaeus monodon, Penaeus (Litopenaeus) vannamei and Penaeus (Litopenaeus) stylirostris.
An effective prevention or treatment means for infections, such as EHP, would be of considerable benefit in aquaculture industries.
Microbial agents are a threat to life on earth beyond the ability to cause disease in a wide variety of living organisms. This is because methanogenic Archaea are responsible for the largest contribution to agricultural greenhouse gas emissions.
Methanogens are not associated with a disease state or parasitism in animals from which they are isolated. However, the production of gases such as methane during fermentation has been identified as a factor involved in increased greenhouse gas emissions and global warming. Therefore methanogens are damaging the planet through their effect on the environment, rather than damaging individual animals through disease.
Ruminants produce the majority of agricultural methane, but are also vital for global food and textile supply. Therefore strategies are required that are able to mitigate the methane output, whilst maintaining or improving production yields.
Dietary strategies to modulate the microbiome of animals to inhibit the proliferation of methanogens, whilst promoting the communities of microbial species that support the health of the animal would meet these objectives.
Milk producing ruminants are subject to the development of mastitis. Mastitis is a bacterial infection that causes an inflammation of a cow's udder. The infection is caused by a wide spectrum of pathogens and, epidemiologically categorized into contagious and environmental mastitis. Mastitis is the most widespread and costly disease in the dairy cattle occurring throughout the world.
Electrical conductivity (EC) of milk has been introduced as an indicator trait for mastitis over the last decade. The EC is determined by the concentration of anions and cations. If the cow suffers from mastitis, the concentration of Na+ and Cl− in the milk increases, which leads to increased electrical conductivity of milk from the infected quarter. Most automatic milking systems have EC sensors incorporated for measuring EC during milking.
A description of the utility of the measurement of electrical conductivity is to be found in J Dairy Sci. 75, 606-614 (1992).
Electrical conductivity measurements in milk from healthy cows are generally between 4.0 and 5.0 milliSiemens (mS) at 25° C., while absolute electrical conductivity values for infected quarters usually range from 5.0 to 9.0 mS. In a typical EC profile for a cow infected with mastitis, the infected quarter shows a higher EC level during most of the milking, with spikes in the beginning and at the end of the milking.
A mild, uncomplicated mastitis in a single quarter is usually treated with intramammary antibiotics, such as β-lactams (amoxicillin, penicillin, and cephalosporins). Systemic antibiotics are used when more than one quarter is infected, when udder changes are marked or when the cow is obviously ill. Combination therapy, with both systemic and intramammary antibiotics, is believed to increase bacteriological cure rates and is used in severe cases of mastitis.
The main components of the economic impact of mastitis are related to the reduction in milk production, milk disposal, the cost of the medicines used in the treatment, the labour costs related to the treatment and the culling of animals. Together, these factors erode the milk income received by farmers. It is estimated that more than $150 million is lost to Australian dairy farmers each year through poor udder health. Moreover the use of antibiotics is now discouraged owing to the development of bacterial resistance and possible undesirable antibiotic residues in the meat and milk of animals for human consumption.

A further example of this disclosure will now be described, as Example 3.
Testing Protocol: Four solutions were evaluated to determine if any could directly inactivate SARS-CoV-2. Of these, solution 4 was a composition of the present disclosure and water was used as a negative control.
Protocol 1: 50 uL of SARS-CoV-2 stocks (undiluted) was added to 50 uL of each solution. After 1 min (simulates length of time spent in the mouth), 500 uL infection media was added to ‘quench’ the disinfection reaction. Samples were then plated directly onto TCID50 plates (n=4/dilution) as soon as possible. The percentage of wells positive for CPE will be recorded, compared to the positive control sample.
100 uL of SARS-CoV-2 stock was exposed to equal volumes (100 uL) of neat and diluted solutions. After lmin, the virus:substrate solution was serially diluted and a TCID50 performed. The change in the TCID50/mL was compared to the positive control sample.
50% Tissue Culture Infectious Dose assay (TCID50): In the PC2 laboratory, plates to establish -95% monolayers of Vero cells were seeded 24 h prior to assay. After verification of quality/density of monolayer, the plates were washed using infection media (to remove any cell debris), then transferred into the PC3 laboratory. Samples were generated, serially diluted and a known volume inoculated into each well. n=4 replicates/sample. Plates were incubated to enable virus infection of monolayers, then MEM infection media (containing pen/strep, glutamine, HEPES, but does not contain FBS)+TPCK trypsin(1 ug/mL) was added. Plates were returned to incubator (37° C., 5% CO2) and microscopically examined every 24 h (up to 72 h) for cytopathic effect (CPE) on cells. The TCID50 /mL of infectious virus present in the original sample was then determined via the method of Reed and Meunch 1938. “A simple method of estimating fifty per cent endpoints” The American Journal of Hygiene:3.
Results: when exposed directly to SARS-CoV-2, solution 4 exhibited viricidal activity that was completely effective. For both the quench and TCID50 assay, when solution 4 was used undiluted, no virus induced CPE could be detected. By contrast, no viricidal effect was evident of solutions 1 & 2. Some viricidal effect was evident for solution 3. The results are graphically shown in
In a further Example 4, a composition of this disclosure was evaluated in a SARS-CoV-2 viral yield reduction assay. sARs-cov-2 patient isolate (Australia/VIC01/2020) virus was used with a sample of the composition being resuspended at 10 mg/mL in infection media (MEM+Abx+HEPES, serum free). Samples were tested at 10 ug/mL, 5 ug/mL, 2.5 ug/mL, 1.25 ug/mL and 0.625 ug/mL (final concentration after addition of virus=5, 2.5, 1.25, 0.625 and 0.313 ug/mL).
Testing Protocol: Seed Vero cells in 24-well plates one day prior to experiment start.
At 24 h and 48 h post infection, an aliquot of supernatant was collected and TCID50 performed to assess infectious virus titre.
50% Tissue Culture Infectious Dose assay (TCID50):
Results: Log TCID50/mL values at 24 h post-infection:
Results: TCID50/mL values at 48 h post-infection:
In a further example 5, vero cells were infected with West Nile virus for two hours and then treated with different concentrations of a composition of this disclosure.
The results for example 5 are shown in
In a further example 6, six species of coccidian protozoa were cultured in 19800 of RPMI medium. These were isolates of the sporozoite lifestage. These species included; Eimeria maxima, Eimeria acervulina, Eimeria brunetti, Eimeria tenella, Eimeria necatrix, Eimeria mitis. These were then treated with 20 μl of a composition of this disclosure.
The results are shown in
In a further example 7, a coccidia challenge trial was performed using Ross 308 male boiler chickens. 1 day old chickens were allocated to experimental groups that included different concentrations of a composition of this disclosure in feed, or the antibiotic ionophore salinomycin in feed or a control group containing no additive in feed. On day 14 the birds were administered a 20 times dosage of a live vaccine preparation containing 3 strains of Eimeria. These included Eimeria Maxima, Eimeria acervulina and Eimeria tenella. 7 days after the Eimeria challenge was administered birds from each treatment group were euthanized and the lesions formed in the gastrointestinal tract by the coccidia infection were scored by a qualified veterinarian.
The results are shown in
In a further example 8, the faecal microbiome of 8 thoroughbred horses was genetically sequenced across 5 days to determine the baseline microbial communities present. 100 ml of a composition of this disclosure was administered every 24 hours for 28 days. The 5 day genetic sequencing of faecal samples was then repeated. The administration of the extract then ceased. After a further 28 days the faecal microbiomes of the 8 horses was again repeated.
The results are shown in
In a further example 9, an assessment was made of the production of infectious influenza A virus (IAV) progeny in the presence of a range of concentrations of a composition of this disclosure (referred to in this example as “Virofonol”) in-vitro (added post-exposure of cells to virus). Quantitative assays were used to measure infectious virus titre.
Influenza A Virus (IAV) (A/Beijing 89 strain—a representative seasonal strain of the H3N2 subtype) was used. Final concentrations of a composition of this disclosure (Virofonol) added after infection with virus for 1 hr—10, 5, and 2.5 m/mL. Virus recovery was assessed at 2 and 24 h post-infection (hpi). The 2 h time point was used to evaluate the residual input virus and the 24 h time point evaluates infectious virus after replication and virus production.
The infection protocol used was as follows:
After 1 h incubation, the inoculum is removed, and all wells are washed 2 times with infection medium.
At 2 and 24 hours post infection (hpi), the supernatant is collected and spun down for 5 min at 13000 rpm in a microcentrifuge. (i.e.: cell free supernatants containing virus are harvested).
The plaque assay protocol used was as follows:
The results obtained were as follows (Table 1):
It will be seen that Virofonol has exhibited anti-viral effects against a representative seasonal IAV strain when added post infection, suggesting an intracellular mechanism of action. Note that no significant change was observed at 2 hpi which is an assessment of input virus before replication is established. The greatest antiviral effect was observed using concentrations of Virofonol exceeding 5 ug/mL added 1 hour post-infection and analysed 24 hours post-infection. This suggests that Virofonol can exert antiviral activity on IAV at a specific stage in the virus life-cycle after the virus has entered and initiated replication.
In a further example 10, an assessment was made of the production of infectious IAV progeny in the presence of a range of concentrations of Virofonol during and after infection in-vitro. TCID50 assay was utilised as a quantitative measure of infectious virus titre as this provides greater technical replicates using less sample and all assays can be performed within the same plate ensuring greater consistency.
Influenza A Virus (IAV) (A/Beijing 89 strain—a representative seasonal strain of the H3N2 subtype) was used. Final concentration during and after addition of virus=5, and 2.5 μg/mL. Virus recovery was at 2 and 24 h post-infection (hpi).
The infection protocol used was as follows:
The TCID50 protocol used was as follows:
The results obtained were as follows (Table 2):
It will be seen that Virofonol has exhibited anti-viral activity against a representative seasonal IAV strain when incubated with the virus as a pre-infection and post-infection treatment. These findings suggest possible viricidal effects of Virofonol directly against the virus as well as cellular mechanisms of action by the compound. Note that no significant change was observed at 2 hpi which is an assessment of input virus before replication is established. The greatest effect was observed with concentrations of Virofonol greater than 5 μg/mL, when viral titres were quantitated 24 hpi.
In a further example 11, an assessment was made of the production of infectious ZIKV virion progeny in the presence of a range of concentrations of Virofonol added during and after infection in-vitro. TCID50 assay was utilised as a quantitative measure of infectious virus titre as this provides greater technical replicates using less sample and all assays can be performed within the same plate ensuring greater consistency. Zika virus (ZIKV) Asian was used with final concentration during and after addition of virus=10, 5, and 2.5 μg/mL. The time points were 24 and 48 h post-infection (hpi).
The infection protocol used was as follows:
The TCID50 protocol used was as follows:
The results obtained were as follows (Table 3):
Virofonol has exhibited anti-viral effects against ZIKV-Asian when incubated with the virus as a pre-infection treatment and maintained in cell culture during the assay. These findings suggest the possible extra-cellular viricidal effects of Virofonol (directly against the virus), as well as an intracellular mechanism of action by the compound (acting on cells). Note that no significant change was observed at 24 hpi which is an assessment of input virus before replication is completely established at 48 hpi. The greatest effect was observed with 5 μg/mL Virofonol after 48 hpi. This suggests that Virofonol effects the virus particle itself (acting against the virus) and/or its ability to infect and replicate within cells (cellular effects). Also note that ZIKV has a longer replication cycle than IAV, thus 2 and 24 hpi were assessed for IAV compared with 24 and 48 hpi for ZIKV.
Overall, examples 9-11 demonstrate that Virofonol has shown antiviral activity when applied directly to the virus inoculum itself and after the infection process for both IAV and ZIKV. These results indicate that Virofonol is useful both as an extracellular and intracellular antiviral agent.
In a further example 12, two compositions of this disclosure (referred to as Polynol and Polygain) were assessed for dose response against (infectious laryngotracheitis virus) ILTV CSW1.
In this example, Chicken (leghorn) liver hepatoma cell line (LMH cells) were seeded into a 12 well plate until 90% confluent.
The results for this example were as follows (Table 4):
In a further example 13, a composition of this disclosure (Polygain) was evaluated for its ability to reduce methane emissions by dry cows.
Dry cows were fed 3 kg concentrate mix (control) or concentrate mixed with 100 g Polygain. Measurements of methane concentration were determined at 11 am and again at 1 pm.
The results in
In a further example 14 a composition of this disclosure (Polygain) was evaluated for its ability to reduce methane generation in vitro. In this example, a sample of rumen fluid was obtained and used to ferment samples of a typical feedlot diet or Rhodes grass. In the sample under evaluation, a concentration of 15% of Polygain was included in each of the fermentations.
The results as set out below show that for the feedlot diet, a 54% reduction in methane generation was achieved after 24 hours per gram of digested dry matter. For the Rhode grass diet, the reduction was 16.5% after 24 hours per gram of digested dry matter.
In a further example 15, a composition of this disclosure (Polygain) was evaluated for its ability to inhibit the polar tube extrusion activity of EHP.
The results shown in
In a further example 16, a composition of this disclosure (Polygain) was evaluated for its ability to enhance milk production in dairy cattle. In this example, cattle were either fed their normal diet (control) or their normal diet including either 0.5% or 1.0% Polygain. Milk volume and concentrate were measured on a daily basis with the results shown in Table 5.
These results show that at 7 days, daily milk production was increased by 2.1 L/day/cow in the cows that were supplemented with Polygain.. This was continued at 41 days where milk production was increased by 1.8 l/day/cow in the cows that were supplemented with Polygain.. These indicate increases of 6.3% and 5.8% respectively.
In addition, protein and fat content were maintained for all of the cows that were supplemented with Polygain.
Finally, a lower level of concentrate was required in the Polygain supplemented cows in order to achieve an enhanced milk yield.
In a further example 17, a composition of this disclosure (Polygain) was evaluated for its ability to enhance the growth of calves. In this trial, calves were either fed their normal diet (control) or their normal diet including 10 g Polygain.
The diet consisted of 4.0 kg wheat, 1.0 kg corn, 1.0 kg canola meal, 0.1 kg limestone, 0.1 kg salt, 0.05 kg dicalcium phosphate, 0.04 kg magnesium oxide and vitamin and trace mineral premix. It was fed as a pellet or loose grain mix.
Results of the trial are set out in Table 6. These show that the average total weight gain for the control group was 67.6 kg as compared with 70.5 kg for the test diet including Polygain. Average daily weight gain for the control group was 0.82 kg compared with 0.86 kg. This amounts to a difference of 4.9% which is highly significant in terms of the economic value of each animal.
Taken in conjunction with the example relating to reduction in methane production, it is evident that the disclosed sugar extracts provide a double benefit. Body mass is enhanced whilst methane production is reduced.
In a further example 18, a composition of this disclosure (Polygain) was evaluated for its ability to improve the health of dairy cattle by preventing and/or treating mastitis. Conductivity data was collected from over 4000 milking sessions from 27 cows over a four month period broken up into a control group and a group having 1% w/w Polygain, on a total dry matter basis, included in their diet.
As previously explained, milk conductivity is directly indicative of the presence of mastitis in a cow. Generally, conductivity increases with incidence of mastitis. It is to be noted that it is unusual for the four quarters of a cow (teats) to be all infected. Therefore by comparing the lowest conductivity quarter with each other quarter as a ratio is indicative of mastitis being present in one or more quarters. Such measurements are typically collected automatically in so-called robotic milking installations. Of course, milk samples may be manually acquired and the conductivity evaluated on a quarter by quarter basis.
In this example 18, the samples were acquired in a robotic milking installation. As shown in Table 7, not only did the average base conductivity decrease over time but the average ratio between the quarters did as well. This is strongly indicative of improved cow mammary gland health likely due to prevention, treatment and/or reduction in the incidence of mastitis.
In a further example 19, a composition of this disclosure (Polygain) was evaluated for its ability to reduce methane emissions by dry cows. Polygain was included in the feed for each of the test groups of cows at 0.5% or 1% w/w on a dry matter basis.
At the commencement of the trial, methane concentrations were captured at periodic times over about a 42 hour period. Methane concentrations were again captured after 32 days of feeding at periodic times over about a 42 hour period.
The results of the trial at 0.5% Polygain are shown in
Referring to
Thus this example 19 shows clearly the dysbiosis effect compositions of this disclosure.
In a further example 20, the faeces of a cow that had been fed on a control diet and a second cow that had been fed on the same diet with the addition of 100 g Polygain were evaluated for methanogenic archea populations.
The results of example 20 are depicted in
