Summary
600 million Chinese are infected with parasites. One of the most important of these is the Asia or Oriental human bloodfluke, Schistosoma japonicum. It causes schistosomiasis (Bilharzia), a very serious and debilitating disease and a major health problem for more than 40 million Chinese living in Southern China. Infection occurs when people make contact with water contaminated by microscopically small cercariae larvae that are released from freshwater snails. As well as humans, Schistosoma japon ....600 million Chinese are infected with parasites. One of the most important of these is the Asia or Oriental human bloodfluke, Schistosoma japonicum. It causes schistosomiasis (Bilharzia), a very serious and debilitating disease and a major health problem for more than 40 million Chinese living in Southern China. Infection occurs when people make contact with water contaminated by microscopically small cercariae larvae that are released from freshwater snails. As well as humans, Schistosoma japonicum infects a number of other mammals, such as water buffaloes, which complicates control efforts. Current control is based on treatment with the drug parziquantel. Vaccines in combination with other control methods, including the use of new drugs, are needed to make elimination of the disease possible. This new program of research has a very strong emphasis on mutual research training and scientific interaction that will: determine whether another drug, artemether, can be used as an aid in control; increase our understanding of the immunological and genetic processes involved in the development of the disease of schistosomiasis; determine the importance of buffalo infections in maintaining human schistosomiasis transmission; undertake genomics and post-genomics research on existing and new discovered S. japonicum molecules that are candidates as new vaccines and diagnostics; and develop a mathematical model that can predict the optimum methods for the sustained control of schistosomiasis in China.Read moreRead less

Summary
Malaria kills many thousands of people each year in Indonesia and PNG. This project will look at better ways to treat and prevent malaria. The team will examine whether using new combinations of drugs in clinics can reduce the amount of severe malaria seen in Papua. The team will examine whether giving people with severe malaria arginine, a naturally occurring amino acid, can increase molecules that may protect against severe malaria. Finally it will examine how lung damage occurs in people with ....Malaria kills many thousands of people each year in Indonesia and PNG.

The team will examine whether giving people with severe malaria arginine, a naturally occurring amino acid, can increase molecules that may protect against severe malaria. Finally it will examine how lung damage occurs in people with severe malaria and whether this can be predicted.Read moreRead less

Summary
New antimalarial drugs are desperately needed. Protein synthesis in Plasmodium falciparum is a validated target for existing drugs and is a promising target for new drugs. This project brings together malaria biologists with chemists and computer scientists to explore this promising field. We will apply modern methods of drug target characterisation to find the most promising enzyme targets involved in protein synthesis and to identify inhibitors as leads for developing antimalarial therapies.

This project brings together malaria biologists with chemists and computer scientists to explore this promising field. We will apply modern methods of drug target characterisation to find the most promising enzyme targets involved in protein synthesis and to identify inhibitors as leads for developing antimalarial therapies. Australian researchers involved in this project will provide expertise in bioinformatic prioritisation of Plasmodium drug targets from the aminoacyl tRNA synthetase family of enzymes. We will use structural modelling and docking experiments to identify promising antimalarial inhibitors, and will optimise assays to assess the effects of these inhibitors. We will also apply modern molecular biology tools to validate these enzymes as anti-malarial drug targets.Read moreRead less
