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.

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
Superbugs and veterinary drugs: are multidrug-resistant zoonotic pathogens residing in Australian animals? Antibiotic resistance is a growing problem affecting human health that is now emerging in animals and veterinary hospitals. This project will integrate surveillance with novel treatments and preventatives to develop effective strategies to limit the impact of resistant bacteria to animal health and prevent transfer between humans and animals.
Exploring the role of the domestic dog and wild rodents as peri-domestic reservoirs of Rickettsia felis. This project aims to explore the role of domestic dogs and wild rats as maintenance hosts for flea-borne spotted fever. Cases of this disease, transmitted to humans by the common dog and cat flea are being increasingly recognised throughout the world. The findings of this study will add significant importance to flea control in pets.
Of pets, vets and antimicrobials: fluoroquinolone use in dogs and resistance biology. Antimicrobial resistance is a current and growing threat relevant to human health, animal welfare, food production, and environmental preservation. This project will provide new insights into the basic science of antimicrobial resistance, through the generation of accurate data on the role of companion animal use of antibiotics on the development and control of resistance. Ultimate project goals are to produce ....Of pets, vets and antimicrobials: fluoroquinolone use in dogs and resistance biology. Antimicrobial resistance is a current and growing threat relevant to human health, animal welfare, food production, and environmental preservation. This project will provide new insights into the basic science of antimicrobial resistance, through the generation of accurate data on the role of companion animal use of antibiotics on the development and control of resistance. Ultimate project goals are to produce recommendations that limit the generation of further resistance. Project outcomes have demonstrable relevance to human preventative health, which is recognised as a national research priority. The health and welfare of pets will also be improved, which has associated community benefits.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.
Retroviral invasion of the koala genome: prevalence, transmission and role in immunosuppressive disease. Koalas are a national symbol yet many of their populations are in decline as a result of habitat loss and disease. Lymphoid cancers and opportunistic infections are significant diseases in both captive and wild koala populations. We previously demonstrated that the recently identified koala retrovirus is associated with lymphoid cancer in koalas. This project will determine the distribution o ....Retroviral invasion of the koala genome: prevalence, transmission and role in immunosuppressive disease. Koalas are a national symbol yet many of their populations are in decline as a result of habitat loss and disease. Lymphoid cancers and opportunistic infections are significant diseases in both captive and wild koala populations. We previously demonstrated that the recently identified koala retrovirus is associated with lymphoid cancer in koalas. This project will determine the distribution of the virus in Australia, the mechanism of its spread and its effect on the immune function of koalas. This research will provide a foundation for better management of captive koalas and for conservation of wild koalas.Read moreRead less

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
A “Goldilocks” live attenuated poultry vaccine for Infectious Coryza. This project aims to develop a safe and effective vaccine for Infectious Coryza using a live-attenuated vaccine approach. Infectious coryza is an acute respiratory disease of chickens and is caused by the bacterial pathogen, Avibacterium paragallinarum. Infectious Coryza can be controlled by appropriate biosecurity practises and this has been successful in the Australian context to date. However, in the USA, Europe and other e ....A “Goldilocks” live attenuated poultry vaccine for Infectious Coryza. This project aims to develop a safe and effective vaccine for Infectious Coryza using a live-attenuated vaccine approach. Infectious coryza is an acute respiratory disease of chickens and is caused by the bacterial pathogen, Avibacterium paragallinarum. Infectious Coryza can be controlled by appropriate biosecurity practises and this has been successful in the Australian context to date. However, in the USA, Europe and other equatorial regions, infectious Coryza remains an unsolved problem. The expected outcome of this project is a cross-serovar protective vaccine to prevent infectious coryza for use in endemic countries and to act as a biosecurity measure to protect Australia's poultry industry against an incursion of this disease.Read moreRead less

Chlamydial infection of the eyes is a significant cause of disease and death in koalas, contributing to the ongoing decline of this native species. Little is known about what influences the outcome of these infections, challenging efforts to manage and control koala chlamydial blindness. This project aims to evaluate whether differences in the infecting Chlamydia pecorum strains or the koala immune response, are associated with the outcome of chlamydial ocular infection. In addition to helping us to understand and prevent blindness in koalas, this project should significantly expand our knowledge of the koala immune system and generate an array of koala immunological assays, outcomes that may benefit all koala conservation efforts.Read moreRead less
