Understanding the biology of reactive oxygen species. This project will utilise forefront technologies to identify and characterise fundamental biological processes involving toxic free radicals that cause infectious disease and cancer. The approach synergises with researchers across disciplines and universities to ultimately identify future drugs to improve and maintain health.

Summary
We will conduct clinical trials to find an effective, simple and cheap oral alternative to injected penicillin for skin sores which could become the universal standard of care whether the patient is in Melbourne or Milingimbi. It would also likely be adopted by the World Health Organization as a standard of care for developing countries. This would lead directly to a reduced burden of skin sores and their complications. It would also open the way for studies to explore even simpler regimens.
Economic, social and cross cultural issues in non-pharmaceutical protection of front line responders to pandemic influenza and emerging infections. The protection of front line responders in a pandemic is essential to underpin an effective response. This research is the only work internationally which will address a key gap in evidence.

The protection of front line responders in a pandemic is essential to underpin an effective response. This research is the only work internationally which will address a key gap in evidence. This research has major implications for the national stockpile and for management of front line responders in a pandemic. These data are urgently needed, not just in Australia, but globally to inform pandemic planning and disease control policy around emerging infections and bioterrorism.Read moreRead less

Summary
Our recent work revealed that, in the Aboriginal population, young age is a risk factor for severe invasive diseases caused by group A streptococcus. For group A streptococcus infection to occur, bacterial attachment is the first step. The bacterium attaches to host cells through interactions involving host fibronectin and the pathogen's fibronectin-binding proteins. We have found that streptococcal strains from severe disease cases are more likely to have the gene for PrtFII, a fibronectin bind ....Our recent work revealed that, in the Aboriginal population, young age is a risk factor for severe invasive diseases caused by group A streptococcus. For group A streptococcus infection to occur, bacterial attachment is the first step. The bacterium attaches to host cells through interactions involving host fibronectin and the pathogen's fibronectin-binding proteins. We have found that streptococcal strains from severe disease cases are more likely to have the gene for PrtFII, a fibronectin binding protein, than those from uncomplicated skin sores. In this application we propose to extend this observation and compare biochemical properties of PrtFII from strains belonging to the above two sets of collections. We hypothesise that PrtFII from invasive strains bind to fibronectin more tightly than the proteins from strains that cause uncomplicated infection. We also will test whether sera from invasive disease cases have lower titre of antibodies to the conserved region of PrtFII than sera from uncomplicated cases. A streptococcal vaccine by necessity has to be a multi-component vaccine to cover a wide spectrum of diseases and epidemiological differences. The study proposed here may provide a basis to argue whether or not to include PrtFII in such a multi-component vaccine.Read moreRead less
The biology, structure and function of bacterial virulence effectors. This project is closely aligned with the National Research Priority of Promoting and Maintaining Good Health and will establish a research framework to investigate novel virulence processes that allow bacterial pathogens to infect humans and cause disease.

This project is closely aligned with the National Research Priority of Promoting and Maintaining Good Health and will establish a research framework to investigate novel virulence processes that allow bacterial pathogens to infect humans and cause disease. This fresh approach to the study of bacterial pathogenesis will sit outside classic genetic methods to investigate infection and immunity which rely heavily on genetic manipulation of the pathogen. Other than providing fundamental information on host-pathogen interactions, this work may lead to novel disease interventions by inhibition of bacterial virulence factor activity and/or enhancement of host inflammatory and immune responses.Read moreRead less
Rhinovirus impairs physiological and immunological lung development and causes exacerbation of allergic airways disease. Rhinovirus (RV) infections account for around 90 per cent of asthma exacerbations, yet the mechanisms behind this are unknown. This project will use mouse models to study the effects of early life RV infection and allergic sensitisation on respiratory and immunological development, with the expectation that early life RV infection disrupts anitgen presenting cell function.
Development and commercialization of novel diagnostic assays for the early detection of acute dengue virus infection. Dengue is an emerging disease of the tropics and is endemic in more than 100 countries with up to 100 million cases annually. Of these, 500,000 result in dengue haemorrhagic fever (DHF), a serious life-threatening complication of dengue virus infection. Dengue activity in northern Australia has increased in recent years with suggestions that it may be coming endemic in this count ....Development and commercialization of novel diagnostic assays for the early detection of acute dengue virus infection.

Of these, 500,000 result in dengue haemorrhagic fever (DHF), a serious life-threatening complication of dengue virus infection. Dengue activity in northern Australia has increased in recent years with suggestions that it may be coming endemic in this country. Early diagnosis, using NS1 based assays should facilitate containment of such outbreaks through earlier identification, treatment, isolation and strategic mosquito control.Read moreRead less

The biosynthesis of structural proteins in parasites. The socio-economic impact of parasitic diseases, in Australia and throughout the world, is enormous- they kill 2-3 million people per year and cost livestock industries billions of dollars per annum. Some are serious food and waterborne threats, such as the coccidia, because they are transmitted from person-to-person via the faecal-oral route, or via ingestion of contaminated water or food, or through the ingestion of cysts in raw or underco ....The biosynthesis of structural proteins in parasites. The socio-economic impact of parasitic diseases, in Australia and throughout the world, is enormous- they kill 2-3 million people per year and cost livestock industries billions of dollars per annum. Some are serious food and waterborne threats, such as the coccidia, because they are transmitted from person-to-person via the faecal-oral route, or via ingestion of contaminated water or food, or through the ingestion of cysts in raw or undercooked meat. They cause diarrhoea, which in some cases, can be life-threatening. We will understand how the coccidia protect themselves as they move from host to host and, through that understanding, develop new ways to control them and eliminate the suffering caused by parasitic diseases.Read moreRead less
