Defining domains within Mycoplasma hyopneumoniae surface proteins that interact with host extracellular matrix: efficacy testing of candidate vaccines in swine. Over 90% of Australian commercial pig production facilities are affected by Mycoplasma hyopneumoniae, the causative agent of swine enzootic pneumonia. This disease causes economic losses in Australia of over $20 million per annum and up to $1 billion per annum in major swine rearing countries worldwide. This project will determine the p ....Defining domains within Mycoplasma hyopneumoniae surface proteins that interact with host extracellular matrix: efficacy testing of candidate vaccines in swine.

This disease causes economic losses in Australia of over $20 million per annum and up to $1 billion per annum in major swine rearing countries worldwide. This project will determine the protective efficacy of new generation vaccines against M. hyopneumoniae, which aim to block the colonisation process and prevent disease .Read moreRead less
Autotransporter proteins of enterohemorrhagic Escherichia coli O157:H7. Escherichi (E.) coli O157:H7 has caused hundreds of outbreaks in the United States and United Kingdom. Although not currently a major problem in Australia, the emergence of E. coli O157:H7 here would have serious implications for our meat and livestock industry. This study will provide important information for the selection of vaccine antigens used to prevent the colonisation of cattle with E. coli O157:H7 and other diarrho ....Autotransporter proteins of enterohemorrhagic Escherichia coli O157:H7. Escherichi (E.) coli O157:H7 has caused hundreds of outbreaks in the United States and United Kingdom. Although not currently a major problem in Australia, the emergence of E. coli O157:H7 here would have serious implications for our meat and livestock industry. This study will provide important information for the selection of vaccine antigens used to prevent the colonisation of cattle with E. coli O157:H7 and other diarrhoeagenic E. coli serotypes. A direct outcome of this will be improved human health, as E. coli O157:H7 can cause life threatening infections in humans. The study will also examine the contribution of specific adhesins to biofilm formation; measures to prevent biofilm formation may reduce the persistence and spread of E. coli O157:H7 in the environment.Read moreRead less

Summary
Investigating the interaction of microRNAs-Wolbachia-Dengue virus in the mosquito vector, Aedes aegypti. This project focuses on using molecular techniques to discover fundamental roles of small RNA molecules (microRNAs) of a key mosquito vector in bacterial symbiosis and Dengue virus infection. It will lead to development of effective approaches in limiting spread of vector and transmission of life threatening viral diseases.
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.
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.
