A link between antibiotic resistance and bacterial sporulation. This project aims to define the sporulation process in the bacterium Clostridium difficile, and advance our understanding of a link between antibiotic use and sporulation. To survive in hostile environments, some bacteria produce a dormant and resilient cell form called a spore which can survive for many years in unfavourable environments, but our understanding of how this process occurs is limited. This project will provide a deepe ....A link between antibiotic resistance and bacterial sporulation. This project aims to define the sporulation process in the bacterium Clostridium difficile, and advance our understanding of a link between antibiotic use and sporulation. To survive in hostile environments, some bacteria produce a dormant and resilient cell form called a spore which can survive for many years in unfavourable environments, but our understanding of how this process occurs is limited. This project will provide a deeper understanding of the sporulation process and the long-lasting detrimental impact of antibiotic use. The project expects to provide economic benefits, reduce environmental microbial contamination and contribute to better health of animals and humans.Read moreRead less
The development and evaluation of a new therapy for the prevention and treatment of bacterial infections in hospitals. The technology used in this project will enable products to be developed from the Australian dairy industry which may safely provide protection and treatment for diarrhoea acquired in hospitals for which there are few effective options. The product will be cost effective and can be used as a public health tool to control outbreaks in those most susceptible to severe disease.
Immunological mechanisms underlying the protective immune responses induced by botulinum oil adjuvanted vaccine. 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 follo ....Immunological mechanisms underlying the protective immune responses induced by botulinum oil adjuvanted vaccine. 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

Summary
A porcine model to provide new insights on scabies immunopathology. Scabies is a poorly understood parasitic disease of medical and veterinary significance. This project will use a world-first experimental model to investigate the progression of host immune responses in scabies, which will enable the development of new control strategies for this neglected disease.
Transport and innate immune properties of DNA in bacterial nano-sized vesicles. All types of living organisms release nano-sized membrane vesicles or “blebs” which they use for intercellular communication and transport of molecules. This project will determine how bacteria package DNA within these vesicles, how this DNA is transported into host cells and how it triggers immune responses in these cells.
The host specificity of bacterial pathogens. The vast majority of microorganisms that cause diseases in animals are host specific. In other words, they cause disease exclusively in a particular animal species, but are harmless for others. Despite considerable recent advances in our understanding of the mechanisms used by microorganisms in general to cause disease, in most cases the underlying basis of host-specificity is not known. In this project, we will use two animal pathogens, rabbit-spe ....The host specificity of bacterial pathogens. The vast majority of microorganisms that cause diseases in animals are host specific. In other words, they cause disease exclusively in a particular animal species, but are harmless for others. Despite considerable recent advances in our understanding of the mechanisms used by microorganisms in general to cause disease, in most cases the underlying basis of host-specificity is not known. In this project, we will use two animal pathogens, rabbit-specific enteropathogenic E. coli and the closely related bacterium, Citrobacter rodentium, which specifically infect rabbits and mice respectively, to investigate the molecular basis of host specificity.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. 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.

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
