Environmental contamination and pig disease: an Australian microbe evolves. 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 t ....Environmental contamination and pig disease: an Australian microbe evolves. 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
Nucleolus targeting by negative strand RNA viruses. Negative strand viruses (NSVs) include diverse animal pathogens that represent significant threats to Australian livestock industries and access to export markets. The project aims to investigate the interface formed by NSVs with cellular nucleoli in order to determine roles in viral manipulation of cell biology during infection. This project hopes to address a major gap in knowledge in virology regarding the fundamental biology of NSVs, and is ....Nucleolus targeting by negative strand RNA viruses. Negative strand viruses (NSVs) include diverse animal pathogens that represent significant threats to Australian livestock industries and access to export markets. The project aims to investigate the interface formed by NSVs with cellular nucleoli in order to determine roles in viral manipulation of cell biology during infection. This project hopes to address a major gap in knowledge in virology regarding the fundamental biology of NSVs, and is expected to redefine our understanding of the virus-host interactions formed by these important pathogens. By determining the mechanisms of NSV-nucleolus interaction, the project plans to also provide important information for the development of new vaccines/therapeutics for livestock to combat NSVs that target nucleoli.Read moreRead less
Development of Novel Pesticidal Agents. We have discovered a family of naturally occurring plant proteins called the cyclotides that have potent insecticidal activity against Helicoverpa species, one of the major pests on cotton and corn in Australia and world wide. Preliminary evidence has shown that they also have activity against major pests to livestock in Australia, including sheep blowflies. To develop these proteins as potential pesticidal agents it is necessary to understand the struct ....Development of Novel Pesticidal Agents. We have discovered a family of naturally occurring plant proteins called the cyclotides that have potent insecticidal activity against Helicoverpa species, one of the major pests on cotton and corn in Australia and world wide. Preliminary evidence has shown that they also have activity against major pests to livestock in Australia, including sheep blowflies. To develop these proteins as potential pesticidal agents it is necessary to understand the structural basis for their activity. We will do this by chemically synthesising peptides with selected residues mutated to determine their effects on activity.Read moreRead less

Australia has amongst the highest reported prevalence allergic conditions (including asthma) in the world. Despite this, little is known about how these conditions arise. Mounting evidence implicates environmentally induced disruption of the genetic blueprint via a process known as epigenetics. We are combining the strengths of a unique collection of identical twins where one of a pair is sensitive to house dust mite, with cutting edge genomics, to characterise the pathways leading to allergy in ....Australia has amongst the highest reported prevalence allergic conditions (including asthma) in the world.

Signalling pathways for sexual differentiation of apicomplexan parasites. This project aims to study the sexual development of apicomplexan parasites, which cause major diseases in humans, livestock and wildlife, including malaria. Only sexually differentiated cells can survive in the mosquito vector and hence this development is essential for the parasite's life-cycle. This project will employ a new approach that separates female from male parasites, thus enabling new information to be gleaned ....Signalling pathways for sexual differentiation of apicomplexan parasites. This project aims to study the sexual development of apicomplexan parasites, which cause major diseases in humans, livestock and wildlife, including malaria. Only sexually differentiated cells can survive in the mosquito vector and hence this development is essential for the parasite's life-cycle. This project will employ a new approach that separates female from male parasites, thus enabling new information to be gleaned about the development of these parasites. The expected outcomes are an understanding of the mechanisms of sexual differentiation and a functional characterisation of novel sex-specific molecules. This will provide significant benefits, such as pivotal prerequisites for new approaches to parasite intervention.Read moreRead less
Mosquito-borne viruses - how they cause disease and novel approaches to prevention. 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. This project has several national benefits. It will elucidate whether there is ....Mosquito-borne viruses - how they cause disease and novel approaches to prevention. 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. 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

The project will also provide research training and career opportunities for developing Australian based researchers.Read moreRead less
Alpha-particles linked to recombinant antibodies targeting tumour cells have potential to effectively treat tumours while minimising normal tissue side effects. We will explore a novel alpha-particle therapy approach to solid tumours, by delivering 225Ac directly into tumour cells, or into cells that support the tumour (microenvironment). This approach will hopefully result in development of a new approach to treatment of cancers that are resistant to conventional therapies.

Summary
Australia has the highest reported prevalence food allergy in the world. Despite this, little is known about how allergy develops. Mounting evidence implicates environmentally induced disruption of the genetic blueprint via a process known as epigenetics. We are combining the strengths of food challenge proven food allergy with assessment of immune functioning & cutting edge genomics, to extensively characterise the pathways leading to food allergy in children.
