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
New mathematical and statistical methods that inform the control of infectious disease outbreaks. Emerging infectious diseases are an ever-present threat to our community, as highlighted by the recent SARS epidemic and current fears concerning avian influenza. The research proposed by this project will help policy makers implement effective border control and outbreak control against a variety of emerging and re-emerging infectious diseases, including SARS, influenza and the deliberate release o ....New mathematical and statistical methods that inform the control of infectious disease outbreaks. Emerging infectious diseases are an ever-present threat to our community, as highlighted by the recent SARS epidemic and current fears concerning avian influenza. The research proposed by this project will help policy makers implement effective border control and outbreak control against a variety of emerging and re-emerging infectious diseases, including SARS, influenza and the deliberate release of an infectious disease such as smallpox. The project will enhance preparedness through a better understanding of the relative merits of different control strategies, and provide new methodology that can dynamically guide border and outbreak control in the midst of an outbreak by making effective use of data.

Ion transport in the malaria parasite and parasitised erythrocyte. This work will contribute to the national research effort in parasitology (an area in which the ARC has established a Research Network), as well as laying the groundwork for subsequent efforts (not part of this grant) to develop new antimalarial strategies.

This work entails an ongoing collaboration between three independent research groups with highly complementary expertise and experience. It will make a significant contribution to the maintenance of Australia's scientific capabilities and training opportunities. The project will yield important insights into the biology of the causative agent of a major human disease, and the mechanism by which the malaria parasite has developed resistance to antimalarial drugs. Although not yet endemic in Australia, malaria is a serious problem in the local region and this work will help Australia meet its obligations to carry out high-quality research that advances our knowledge in this area.

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

It will also develop methods to design robust and nonlinear filters and coherent observers for nonlinear and finite level quantum systems and apply these results to the design of robust measurement based quantum controllers. In addition, the project will apply coherent and measurement based robust control methods to achieve useful emergent behaviours in nonlinear quantum networks. Such emergent behaviours may involve the robust reduction of decoherence effects and the robust solution of quantum computational problems. Read moreRead less
Regulating nutrient uptake in intracellular parasites. Parasites impose a major economic and medical burden on human societies. In order to grow and reproduce, parasites scavenge nutrients from their animal or human hosts. As they move within and between hosts they encounter different levels of nutrients; how they adapt to these differences is poorly understood. This project aims to investigate the mechanisms by which the model parasite Toxoplasma senses and responds to the nutrients in its envi ....Regulating nutrient uptake in intracellular parasites. Parasites impose a major economic and medical burden on human societies. In order to grow and reproduce, parasites scavenge nutrients from their animal or human hosts. As they move within and between hosts they encounter different levels of nutrients; how they adapt to these differences is poorly understood. This project aims to investigate the mechanisms by which the model parasite Toxoplasma senses and responds to the nutrients in its environment, thereby shedding light on how they adapt to the different environments that they inhabit and, in the longer term, informing novel treatment strategies that aim to limit the parasites’ nutrient supply.Read moreRead less
A novel family of amino acid transporters in Apicomplexan parasites. Apicomplexan parasites are single celled organisms that are the causative agents of major diseases in livestock and humans.

Apicomplexan parasites are single celled organisms that are the causative agents of major diseases in livestock and humans. However, the basic biochemistry of these intracellular parasites is poorly understood, and there are limited treatments available for the diseases these parasites cause. The project hypothesis is that a novel family of proteins that are unique to apicomplexan parasites play a key role in the uptake of essential nutrients (amino acids) into these organisms. This project aims to use a combination of genetic, biochemical and physiological methods to understand the function of these proteins, the role(s) that they play in apicomplexan biology, and their importance for parasite survival.Read moreRead less
