Ross River virus - identification of virulence determinants in clinical isolates from across Australia. In Australia, Ross River virus (RRV) is the most common insect borne virus that affects human health. There were more than 60,000 confirmed cases of RRV between 1993 and 2008. While not fatal, the disease is responsible for significant morbidity that has both social and economic costs for the individual, their family and the community. The project has several national benefits. It will elucida ....Ross River virus - identification of virulence determinants in clinical isolates from across Australia. In Australia, Ross River virus (RRV) is the most common insect borne virus that affects human health. There were more than 60,000 confirmed cases of RRV between 1993 and 2008. While not fatal, the disease is responsible for significant morbidity that has both social and economic costs for the individual, their family and the community. The project has several national benefits. It will elucidate whether there is any association between RRV strain and the severity of human disease. It will also identify viral markers that could assist public health officials in determining likely disease outcomes of outbreaks and could provide new avenues for the design of antiviral strategies.Read moreRead less

While not fatal, the disease is responsible for significant morbidity that has both social and economic costs for the individual, their family and the community. This project has several national benefits. It will elucidate whether there is an association between RRV strain and the severity of disease and if there are human factors that affect the seriousness of symptoms. Knowledge of both of these could provide new avenues for the design of prevention and treatment strategies.Read moreRead less
Risks to human health and the ecosystem from feral pigs in Perth metropolitan water catchments. This project aims to investigate the potential risk feral pigs pose to public health through the dissemination of water borne pathogens within water catchment areas, and to investigate their role in the maintenance and spread of diseases of public and animal health concern in the south west of Western Australia. As well as providing a frontline approach to protecting our water supplies, this project ....Risks to human health and the ecosystem from feral pigs in Perth metropolitan water catchments. This project aims to investigate the potential risk feral pigs pose to public health through the dissemination of water borne pathogens within water catchment areas, and to investigate their role in the maintenance and spread of diseases of public and animal health concern in the south west of Western Australia. As well as providing a frontline approach to protecting our water supplies, this project will also provide valuable data on the nature and extent of the risk feral pigs pose to biodiversity conservation and the environment generally. The outcomes of this research will provide a scientific basis for the development of prioritised strategies for the control of feral pigs in Western Australia.Read moreRead less
Detection and viability of waterborne pathogens using a gut-on-chip. This project aims to resolve a significant problem for water utilities. Microbial pathogens Cryptosporidium, norovirus and adenovirus are the main public health concern for drinking water in developed nations. Water monitoring is limited by the lack of fast, reliable detection methods and viability assays for these pathogens. This project will use a novel gut-on-a-chip to develop for the first time rapid infectivity assays for ....Detection and viability of waterborne pathogens using a gut-on-chip.

Water monitoring is limited by the lack of fast, reliable detection methods and viability assays for these pathogens. This project will use a novel gut-on-a-chip to develop for the first time rapid infectivity assays for Cryptosporidium, norovirus and adenovirus. Significant benefits include improved diagnostics and water disinfection assays, improved water treatment and reduced costs with global impact.Read moreRead less
Lizard social networks and the spread of parasites. Australian ecosystems are continually threatened by new epidemics of diseases and parasites, some local, others from overseas. Examples include the facial tumours of Tasmanian devils and the fungus that threatens many native frog species. To manage these epidemics effectively, we must understand how they spread through animal populations. This project will help to protect our fauna from invasive diseases. It contributes to sustaining the biodiv ....Lizard social networks and the spread of parasites. Australian ecosystems are continually threatened by new epidemics of diseases and parasites, some local, others from overseas. Examples include the facial tumours of Tasmanian devils and the fungus that threatens many native frog species. To manage these epidemics effectively, we must understand how they spread through animal populations. This project will help to protect our fauna from invasive diseases. It contributes to sustaining the biodiversity of the country. With better knowledge of how diseases of wildlife spread, we can develop more effective control of those diseases thereby protecting wildlife species, animal populations and, ultimately, Australian ecosystems.Read moreRead less
Maintaining fidelity in viral Ribonucleic acid (RNA) polymerases. This project will provide informed insights into the dynamics of viruses that currently impact a healthy start to life, ageing well and productively, and preventative healthcare. The analysis of viruses that cause gastroenteritis outbreaks will increase our understanding of how these viruses replicate and spread.
Innovative approaches to understanding and limiting the public health risks of Cryptosporidium and Giardia in animals in Australian catchments. Sophisticated molecular typing and modelling will be used to determine if chlorine-resistant parasites in animals in catchments are responsible for infection in humans. Improved catchment management and risk mitigation strategies will be developed during this project, which will make a substantial contribution to the provision of safe drinking water acro ....Innovative approaches to understanding and limiting the public health risks of Cryptosporidium and Giardia in animals in Australian catchments.

Antigenic analysis of the surface of Cyclospora cayetanensis oocysts. Infection with Cyclospora cayetanensis is an emerging disease that causes significant morbidity in human populations. Although prevalent in developing countries, recent outbreaks in the USA confirm it is now emerging into the developed world.

Infection with Cyclospora cayetanensis is an emerging disease that causes significant morbidity in human populations. Although prevalent in developing countries, recent outbreaks in the USA confirm it is now emerging into the developed world. The research described here will analyse and characterise the antigens on the surface of the oocyst of C. cayetanensis which will add significantly to our sparse knowledge on this important human parasite. We will also develop the first commercial antibodies and technologies which will rapidly and accurately detect the parasite in human patients and our drinking water supplies, thus securing a global market for Australian technology.Read moreRead less
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.
Development of SELEX technology (Systematic Evolution of Ligands by EXponential enrichment). A recently developed in vitro genetic selection technique has allowed the isolation of oligonucleotides that can bind target molecules with high affinity and specificity.

A recently developed in vitro genetic selection technique has allowed the isolation of oligonucleotides that can bind target molecules with high affinity and specificity. The strategy know as SELEX (Systematic Evolution of Ligands by EXponential enrichment) uses protein biochemistry and PCR technology, with subsequent repeated rounds of selection and amplification, to screen vast libraries of oligonucleotides (RNA or DNA) for their ability to bind target proteins. This procedure will be developed by UNSW in collaboration with the biotech company BTF Plc., Ltd., to be used in two applications. The first is the research interest of UNSW and involves the development of aptamers against hepatitis C virus. The second lies within the interests of BTF and will involve the development of aptamers against the water borne pathogen Cryptosporidium parvum.Read moreRead less
