Botulism is recognised as an important bacterial pathogen in commercial beef cattle in Australia and around the world. Development of affective, well-researched vaccine against Clostridium botulinum is a high priority for the cattle industry. A novel oil adjuvanted vaccine (Singvac from Fort Dodge Pty Ltd) has advantage over conventional vaccines as it provides full protection following a single administration. The aims of this study are to investigate the immunological mechanisms underlying the protective response by this novel vaccine using bovine and murine models. This study will discover new control measures for botulism in Australia.Read moreRead less

Bacterial and host drivers of chlamydial blindness in koalas. 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 ou ....Bacterial and host drivers of chlamydial blindness in koalas. 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

Development of a live vaccine for gut health in poultry. The project aims to develop a live vaccine against necrotic enteritis, a disease of poultry estimated to cost the global poultry industry $5-6 billion USD/annum. It builds on work that has demonstrated the efficacy of an experimental vaccine. The proven antigen, NetB, will be expressed in live delivery vehicles, including the apicomplexan parasite Eimeria and several bacteria strains particularly suited to use in chickens. Comparative analysis of the different vaccine vehicles will allow evaluation of the relative advantages and disadvantage of the different vehicles for delivery of heterologous vaccine antigens, thus informing the choice of appropriate vectors for this and other vaccine applications.Read moreRead less

The Type IX Secretion System present in diverse bacteria of veterinary, agricultural, environmental and industrial importance enables effector proteins to be secreted and attached to the cell surface where they contribute to disease pathogenesis or degrade biopolymers of commercial interest. This project aims to determine the structure and assembly mechanism of this complex secretion nanomachine comprising 15 different proteins using state of the art microscopy. Knowledge of the structure will greatly enhance our understanding of secretion mechanisms and our ability to both inhibit the system to treat disease in animals or manipulate the system for industrial applications providing future economic and environmental benefits to our nation.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
Environmental contamination and pig disease: an Australian microbe evolves. The Australian pig industry produces pork commodities from over 4.75 million pigs per year.

The Australian pig industry produces pork commodities from over 4.75 million pigs per year. Infectious diseases in industrial-scale piggeries can have a devastating effect on pork production, particularly on feed conversion efficiency and growth rates, and can pose downstream environmental contamination and food safety risks. This project aims to assess a current infectious disease problem in pigs by studying a microbe that appears to have uniquely evolved in Australia. These results could inform the rational design of monitoring, prevention and treatment strategies to minimise infection outbreaks in Australian pigs and may result in production benefits to the pork industry, reduced environmental microbial contamination and safer food.Read moreRead less
