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
Alphaherpesvirus recombination: safety implications for attenuated Herpesvirus vaccines. Under certain conditions some herpesviruses, including mild vaccine strains, can recombine to generate virulent viruses. Following findings that this occurred naturally between Australian poultry vaccines, with devastating results, this project will study natural herpesvirus recombination with the aim of allowing vaccines to be used more safely.
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

This project aims to establish reference laboratories as biobanks for resistant isolate collections from veterinary diagnostic laboratories / surveillance programmes and a national research network to mitigate antimicrobial resistance in animals. Antimicrobial resistance in zoonotic/foodborne pathogens and livestock commensals is a global issue. This project will use mass-spectroscopy biotypers, information management software, robotic liquid handling and a research dairy to develop high-throughput screening technologies to rapidly determine major animal species’ resistance status, and research anti-infectives and vaccines for livestock diseases. This will improve the health and production of Australian livestock, leading to greater market access for high quality products.Read moreRead less

Chlamydial infections of birds, domesticated animals and humans. This project aims to investigate the epidemiology of an avian Chlamydia pathogen that is known to infect humans and animals, causing serious disease. Utilising molecular epidemiology approaches, this project will generate new knowledge about dynamics of where, when and how this infection spill-over occurs between different hosts.

This project aims to investigate the epidemiology of an avian Chlamydia pathogen that is known to infect humans and animals, causing serious disease. Utilising molecular epidemiology approaches, this project will generate new knowledge about dynamics of where, when and how this infection spill-over occurs between different hosts. This project also aims to extend early development work on an innovative diagnostic system for detection of chlamydia in laboratory and point-of-care scenarios. The expected outcomes are a greatly enhanced understanding of infections in humans and animals caused by this understudied pathogen, which will allow for more effective control and management of these infections.Read moreRead less
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.
What role does wildlife play in emergency disease? The case of the feral pig. Wildlife populations have been responsible for many disease emergencies with economic and human health impacts, but our current understanding limits their management. This project focuses on the feral pig, an introduced wildlife species. It will develop an understanding of disease spread in feral pigs and from feral pigs to cattle. Using feral pig disease genetics, climate and environmental data, disease spread models ....What role does wildlife play in emergency disease? The case of the feral pig. Wildlife populations have been responsible for many disease emergencies with economic and human health impacts, but our current understanding limits their management. This project focuses on the feral pig, an introduced wildlife species. It will develop an understanding of disease spread in feral pigs and from feral pigs to cattle. Using feral pig disease genetics, climate and environmental data, disease spread models will be developed. These models will be used to better manage emergency disease outbreaks in feral pigs and other wildlife species. This project will deliver practical outcomes, such as the best method of discovering disease and the most effective methods to control emergency animal diseases in wildlife and domestic animals.Read moreRead less
Using RNA interference to combat the worst emerging disease of wildlife. This project aims to develop a novel method of disease control in wildlife. It will use recent advances in RNA interference technology to knockdown virulence genes in an emerging pathogen that threatens biodiversity. Pathogens such as the amphibian chytrid fungus continue to cause widespread extinction and urgently require better control methods.

This project aims to develop a novel method of disease control in wildlife. It will use recent advances in RNA interference technology to knockdown virulence genes in an emerging pathogen that threatens biodiversity. Pathogens such as the amphibian chytrid fungus continue to cause widespread extinction and urgently require better control methods. RNA interference has been used to increase disease resistance to fungi in plants but adapting this approach for animals will have wide relevance in combatting fungi and other pathogens. The specific outcomes of this method will be to increase survival rates in a broad range of frog species to improve the success of captive release programs worldwide and hence save frogs from extinction.Read moreRead less
Emergence and evolution of a multi-host pandemic: amphibian chytridiomycosis as a model. Emerging infectious diseases are contributing to the sixth mass extinction. This study will focus on the most important disease, chytridiomycosis, which has caused the extinction of hundreds of amphibian species. It will examine the reasons for its emergence and how it is evolving - this will improve management of it and other emerging diseases.
