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.

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
A next-generation whole parasite bovine Babesia vaccine. . In Australia, Babesia parasites cause most of the severe and often fatal cases of cattle-tick fever, a globally significant tick-borne disease. It can be prevented by a live-attenuated parasite vaccine which has critical limitations of a 4-day shelf-life and risk of severe disease if administered to adult cattle. This project aims to evaluate in cattle a novel whole parasite Babesia bovis vaccine that cannot cause disease and can be pres ....A next-generation whole parasite bovine Babesia vaccine. . In Australia, Babesia parasites cause most of the severe and often fatal cases of cattle-tick fever, a globally significant tick-borne disease. It can be prevented by a live-attenuated parasite vaccine which has critical limitations of a 4-day shelf-life and risk of severe disease if administered to adult cattle. This project aims to evaluate in cattle a novel whole parasite Babesia bovis vaccine that cannot cause disease and can be preserved as an off-the-shelf product without losing efficacy. The expected outcome is a significantly improved vaccine for a major infectious disease that affects primary food production. As the disease imposes a major economic burden, it will have great benefit for the Australian livestock industry.

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
