Phase-variable epigenetic regulators in bacterial veterinary pathogens. This project aims to identify phasevarion regulated genes in the major bacterial swine pathogens Streptococcus suis and Actinobacillus pleuropneumoniae. Both species contain randomly switching epigenetic regulators that control expression of multiple genes by epigenetic mechanisms. Identifying phasevarion controlled genes will inform and direct future vaccine development for important livestock species.
Defining the molecular basis for Salmonella persistence. Salmonella infections in animals and humans place significant burdens on the agri-food and healthcare sectors. All mammals and avian species can become chronically infected with Salmonella and such chronic carriage is a reservoir for disease and outbreaks in other animals and humans. Significant gaps in our understanding of Salmonella infection remain, including the molecular mechanisms involved in establishing a chronic carrier state. We ....Defining the molecular basis for Salmonella persistence. Salmonella infections in animals and humans place significant burdens on the agri-food and healthcare sectors. All mammals and avian species can become chronically infected with Salmonella and such chronic carriage is a reservoir for disease and outbreaks in other animals and humans. Significant gaps in our understanding of Salmonella infection remain, including the molecular mechanisms involved in establishing a chronic carrier state. We identified several Salmonella specific genes and subsequent murine studies revealed that a Salmonella mutant lacking these genes is attenuated in mice and especially in the gallbladder. In this project we seek to understand the molecular basis for attenuation and the contribution of each protein to diseaseRead moreRead less
Development of a safe and immunogenic anti-chlamydia vaccine for the koala. Many koala populations are under threat of extinction from chlamydial disease.The project will develop a chlamydial vaccine and conduct trials in several wild koala populations for safety and effectiveness.
Understanding the origin, epidemiology and transmission threat of chlamydial infections between Australian native animals and livestock. Chlamydial infections of koalas and livestock cause diseases of significant economic and environmental concern. Molecular analysis of livestock and native animal strains will improve understanding of the factors associated with transmission of these important pathogens, improving the ability to manage affected Australian animal populations.
Treating Equine Laminitis. This project aims to explore the causes of equine laminitis, and to work with a newly-established Australian biopharma company to develop the world's first anti-laminitis medication. Equine laminitis is a painful, crippling disease of the foot, often necessitating euthanasia, and is the second-most common cause of death in domestic horses. In 2007, a landmark study identified insulin toxicity as a primary cause of laminitis, and subsequent research has identified over- ....Treating Equine Laminitis. This project aims to explore the causes of equine laminitis, and to work with a newly-established Australian biopharma company to develop the world's first anti-laminitis medication. Equine laminitis is a painful, crippling disease of the foot, often necessitating euthanasia, and is the second-most common cause of death in domestic horses. In 2007, a landmark study identified insulin toxicity as a primary cause of laminitis, and subsequent research has identified over-stimulation of the IGF-1 receptor as the most likely mechanism. This project aims to prove that mechanism and to develop an effective treatment.Read moreRead less
Slipping out unnoticed: a new bacterial lipoprotein transport system. Worldwide markets for biotechnology-derived products are projected to grow to at least $50 billion per year for the next 10 years. The cornerstone of biotechnology is the production of proteins. The applicant has discovered a new pathway for protein production in bacteria. The primary objective of this project is to use a diverse array of biochemical and biophysical techniques to understand how this new protein production pl ....Slipping out unnoticed: a new bacterial lipoprotein transport system. Worldwide markets for biotechnology-derived products are projected to grow to at least $50 billion per year for the next 10 years. The cornerstone of biotechnology is the production of proteins. The applicant has discovered a new pathway for protein production in bacteria. The primary objective of this project is to use a diverse array of biochemical and biophysical techniques to understand how this new protein production platform works. We will also assess this new pathway for the production of proteins of interest to the biotechnology sector. This project expects to determine how this system can be exploited for use in the growing Australian bioeconomy.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
Improving diagnostic accuracy and treatment options for equine PPID. Equine Pituitary Pars Intermedia Dysfunction (PPID) is a common, chronic and potentially life-threatening disease of older horses and ponies. Although a treatment is available, the disease is poorly understood and there are some concerns that the current diagnostic technology is not delivering accurate results. Thus, this project aims to develop a more accurate diagnostic test for PPID, while exploring the relationship between ....Improving diagnostic accuracy and treatment options for equine PPID. Equine Pituitary Pars Intermedia Dysfunction (PPID) is a common, chronic and potentially life-threatening disease of older horses and ponies. Although a treatment is available, the disease is poorly understood and there are some concerns that the current diagnostic technology is not delivering accurate results. Thus, this project aims to develop a more accurate diagnostic test for PPID, while exploring the relationship between PPID and metabolic syndrome, to generate new insights into the cause and consequences of both diseases. As an added benefit, the project will assist horseracing laboratories to improve their detection methods for peptide doping in younger competition horses.

Harnessing the genome of the Australian paralysis tick to develop effective control products. This project aims to examine the potent cocktail produced by the salivary gland of Australia's paralysis tick. The paralysis tick continues to cause severe illness and deaths for companion pets with up to 100,000 cases of toxicoses per year. This project aims to develop new safe treatments and/or preventative vaccines.

The VetCompass data service intends to collect real-time records from veterinary clinics and aggregate them for researchers to interrogate. It aims to provide Australian researchers with sustainable and cost-effective access to authoritative data from hundreds of practitioners in Australia and the United Kingdom. These data will be essential for research on disease distribution and determinants, and surveillance and diagnostics that underpin evidence-based practice. The expected outcomes include identification of the most prevalent disorders and their causes and optimal treatments. The data may also revolutionise clinical auditing in Australia, help the veterinary profession to rank research priorities, and inform companion animal and equine curricula in our universities.Read moreRead less
