Reduction of antibiotic usage in the commercial pig industry. This project intends to identify factors that make a pig enterprise more likely to use high levels of antibiotics and develop alternative, vaccination-based methods for disease control. The development of multi-drug resistance in zoonotic bacterial pathogens (e.g. Salmonella and Campylobacter spp.) in pigs has raised concerns that antimicrobial resistance can be transferred from livestock to humans. Although the epidemiology to suppor ....Reduction of antibiotic usage in the commercial pig industry. This project intends to identify factors that make a pig enterprise more likely to use high levels of antibiotics and develop alternative, vaccination-based methods for disease control. The development of multi-drug resistance in zoonotic bacterial pathogens (e.g. Salmonella and Campylobacter spp.) in pigs has raised concerns that antimicrobial resistance can be transferred from livestock to humans. Although the epidemiology to support a claim that there is a causal association between antimicrobial use in food animals and public health is complex there is universal agreement that use of antimicrobials in food animal production should be minimised. This project intends to deliver outcomes that will reduce antibiotic use on commercial pig farms.Read moreRead less
Improving the diagnosis, management and control of chlamydial infections in Australian livestock. Chlamydial diseases, such as arthritis and encephalomyelitis, are associated with significant economic losses for Australian livestock producers. Effective surveillance and management of Chlamydia infections is problematic due to: the absence of epidemiological data; the lack of an accurate and easily interpretable diagnostic test; and the lack of an available vaccine. This project aims to evaluate ....Improving the diagnosis, management and control of chlamydial infections in Australian livestock. Chlamydial diseases, such as arthritis and encephalomyelitis, are associated with significant economic losses for Australian livestock producers. Effective surveillance and management of Chlamydia infections is problematic due to: the absence of epidemiological data; the lack of an accurate and easily interpretable diagnostic test; and the lack of an available vaccine. This project aims to evaluate factors associated with chlamydial disease in Australian livestock and thereby improve on-farm diagnosis. With the concomitant development of a chlamydial vaccine for sheep, this project aims to provide veterinarians and producers with important tools to reduce the on-farm impacts of chlamydial disease.Read moreRead less
Chemo-prevention of tropical canine parasitoses and vector-borne diseases. This project will determine the prevalence and diversity of established, emerging and novel canine vector-borne agents and endoparasites in a tropical setting by using conventional and next generation molecular diagnostic tools. It will fill an important gap by providing independently-verified evidence on how well canine anti-parasitic products marketed in Australia and Asia by Bayer Animal Health, perform in high-infecti ....Chemo-prevention of tropical canine parasitoses and vector-borne diseases. This project will determine the prevalence and diversity of established, emerging and novel canine vector-borne agents and endoparasites in a tropical setting by using conventional and next generation molecular diagnostic tools. It will fill an important gap by providing independently-verified evidence on how well canine anti-parasitic products marketed in Australia and Asia by Bayer Animal Health, perform in high-infection pressure settings, as a chemo-preventative for these disease agents. Tropical regions spanning northern Australia and Southern Asia are highly conducive to a plethora of canine vector-borne and parasitic pathogens that cause significant morbidity and mortality in dogs. Many of these agents also pose a risk to public health. The outcomes will be directly translated to best-practice guidelines for the advancement of companion animal (and indirectly human) health and welfare.Read moreRead less
Using adaptive and innate immunity to chytridiomycosis to save amphibians from extinction. Chytridiomycosis has been implicated in the decline or extinction of hundreds of frog species worldwide since its emergence in the 1970s. The goal of this project is to identify immune frogs for captive breeding and successful reintroduction, screen populations to predict their risk of decline and develop targeted vaccines.
Emergence of a virulent strain of West Nile virus causing fatal equine encephalitis in south-eastern Australia. In 2011 a large outbreak of encephalitis in horses occurred in south-eastern Australia that was caused by a new virus that is transmitted by mosquitoes and is related to West Nile virus, known to cause severe disease in humans and horses. This project will study this new virus and develop improved methods for diagnosis and control of this disease.
Molecular approaches to solving current and emerging problems in the epidemiology and diagnosis of Marek's disease in Australia. Marek's disease (MD) is a ubiquitous viral disease of chickens that is currently controlled in meat chickens by blanket vaccination of all chickens. However, as has happened overseas, the efficacy of the HVT vaccine being used in Australia is breaking down resulting in subclinical and clinical losses due to MD. To assist industry deal with this situation we propose to ....Molecular approaches to solving current and emerging problems in the epidemiology and diagnosis of Marek's disease in Australia. Marek's disease (MD) is a ubiquitous viral disease of chickens that is currently controlled in meat chickens by blanket vaccination of all chickens. However, as has happened overseas, the efficacy of the HVT vaccine being used in Australia is breaking down resulting in subclinical and clinical losses due to MD. To assist industry deal with this situation we propose to develop novel molecular methods for the quantification of Marek's disease viruses (MDV) in the host and the environment, to use these methods to design effective early monitoring systems for MD in broilers that predict disease and performance outcomes, and to develop an epidemiological model that will predict the spread and severity of MD as failure of vaccinal protection progresses.Read moreRead less
Reducing antibiotic usage in pig herds: controlling Lawsonia intracellularis by vaccination, housing and hygiene. Pigs are major consumers of antibiotics in Australia. Many of these antibiotics are fed to pigs to prevent proliferative enteritis (PE). There are increasing public concerns regarding the development and spread of antibiotic-resistant bacteria and the potential impact on human health. The adoption of an effective commercial vaccine to prevent PE will reduce the volume of antibiotics ....Reducing antibiotic usage in pig herds: controlling Lawsonia intracellularis by vaccination, housing and hygiene.

The adoption of an effective commercial vaccine to prevent PE will reduce the volume of antibiotics used in the pig industry and hence reduce the risk of antibiotic-resistant bacteria developing.Read moreRead less
Using molecular tools to understand and control the transmission of Cryptosporidium. Cryptosporidium is the major public health concern of water utilities as the parasite has a global impact on the health and survival of millions of people and animals worldwide. It is resistant to chlorine and there are no effective drugs against it. Control strategies therefore rely on understanding how it is transmitted. This project will conduct a comprehensive study utilising molecular tools to determine if ....Using molecular tools to understand and control the transmission of Cryptosporidium. Cryptosporidium is the major public health concern of water utilities as the parasite has a global impact on the health and survival of millions of people and animals worldwide. It is resistant to chlorine and there are no effective drugs against it. Control strategies therefore rely on understanding how it is transmitted. This project will conduct a comprehensive study utilising molecular tools to determine if the Cryptosporidium in humans is the same as that derived from water contamination sources (animals, sewage etc). The outcomes of this project will result in the development of more targeted, cost-effective preventive measures to minimize exposures to infections, accurate risk assessment, and scientific management of the watershed.Read moreRead less
