Gastrointestinal parasites and their diagnosis. Gastrointestinal disease such as diarrhoea, abdominal pain and irritable bowel syndrome are common in the Australian population and there are a wide variety of causes, including potentially parasites. The parasite Dientamoeba fragilis has, until recently, been overlooked as a cause of human disease, but recent studies have confirmed its role as a pathogen. This project seeks to improve the diagnosis of this organism in faeces and this development ....Gastrointestinal parasites and their diagnosis.

The parasite Dientamoeba fragilis has, until recently, been overlooked as a cause of human disease, but recent studies have confirmed its role as a pathogen. This project seeks to improve the diagnosis of this organism in faeces and this development will allow effective treatment to be used in patients thereby ameliorating disease.Read moreRead less
Brain metabolic changes in experimental malaria: a paradigm for the molecular mechanisms of intravascular inflammation. Malaria is endemic in countries directly to the north of Australia, as close as Papua New Guinea and East Timor. This project's findings about malaria also will have relevance to other infectious diseases of national importance. The outcomes will contribute to Australia's research reputation. We will build international links that will increase the national knowledge base and r ....Brain metabolic changes in experimental malaria: a paradigm for the molecular mechanisms of intravascular inflammation. Malaria is endemic in countries directly to the north of Australia, as close as Papua New Guinea and East Timor. This project's findings about malaria also will have relevance to other infectious diseases of national importance. The outcomes will contribute to Australia's research reputation. We will build international links that will increase the national knowledge base and research skill base. Young scientists will be trained in state-of-the-art research techniques in a cross-disciplinary environment that is the way of future biological research. The project may identify potential drug targets for malaria or other infectious diseases. The Intellectual Property will be protected and commercialised.Read moreRead less
Developing novel chemistries for removing environmental surface biofilms to reduce hospital acquired infections. This project will develop new detergents that more efficiently clean hospitals. This will increase hospital safety by decreasing infections, thus saving lives and healthcare costs.
Analysing the protective role of platelets during malaria infection. Platelets protect the host during malarial infection. This project aims to study how platelets kill the malaria parasite by investigating the role of host molecules and their potential as novel antimalarial agents. The role of platelets in the pathogenesis of cerebral malaria syndrome will also be investigated.
Functional and structural diversity of the cathepsin L peptidase from the human blood fluke Schistosoma mansoni. Peptidases are enzymes that are important in many infectious and physiological disease states. For example, they are used by infectious pathogens to enter human tissues and survive inside their bodies. The same type of enzymes also contribute to tissue damage in many pathological processes in humans such as cancer, arithritis and osteoporosis. There is an urgent need to define their s ....Functional and structural diversity of the cathepsin L peptidase from the human blood fluke Schistosoma mansoni. Peptidases are enzymes that are important in many infectious and physiological disease states. For example, they are used by infectious pathogens to enter human tissues and survive inside their bodies. The same type of enzymes also contribute to tissue damage in many pathological processes in humans such as cancer, arithritis and osteoporosis. There is an urgent need to define their structure and properties so that we can employ rational approaches to develop new drugs that can combat these diseases and ailments. Read moreRead less
Aminopeptidases involved in regulating the amino acid pool in malaria parasites. Aminopeptidases are pivotal to the normal functions of all cells. Abnormalities in their function and/or structure results in tissue damage in many pathological processes in humans such as cancer, neuronal diseases and hormonal action. They are also critical to viral, bacterial and parasitic infections as they are employed to remove amino acids from the host for use in building their own proteins. This project bring ....Aminopeptidases involved in regulating the amino acid pool in malaria parasites. Aminopeptidases are pivotal to the normal functions of all cells. Abnormalities in their function and/or structure results in tissue damage in many pathological processes in humans such as cancer, neuronal diseases and hormonal action. They are also critical to viral, bacterial and parasitic infections as they are employed to remove amino acids from the host for use in building their own proteins. This project brings national and international expertise together to define the structure and biological properties of these essential enzymes so that in the future we can employ rational approaches to develop new drugs that can combat these diseases and ailments.Read moreRead less
Chromera velia - a new organism for understanding malaria and related parasitic diseases. Malaria and related parasitic diseases cause millions of deaths annually. Chromera velia is a recently discovered organism that was isolated from Australian corals and is the closest known relative to these parasites. Chromera is able to photosynthesis and live in the absence of a host, making it an excellent organism for developing antimalarial drugs. In this project we will determine key features of Chro ....Chromera velia - a new organism for understanding malaria and related parasitic diseases. Malaria and related parasitic diseases cause millions of deaths annually. Chromera velia is a recently discovered organism that was isolated from Australian corals and is the closest known relative to these parasites. Chromera is able to photosynthesis and live in the absence of a host, making it an excellent organism for developing antimalarial drugs. In this project we will determine key features of Chromera ecology, morphology, genetics and biochemistry. The resulting data will allow us to exploit Chromera as a model for developing anti-parasitic drugs and for understanding parasite evolution. Read moreRead less
