There is no vaccine for malaria and current drugs are failing, contributing to millions of malaria-related deaths each year. The aim of this project is to develop new drugs to address this significant global health issue. This project will focus on drugs that act in novel ways to existing malaria drugs by targeting enzymes that are involved in altering gene expression in the parasite. These kinds of enzymes are recognised drug targets in other diseases such as cancer. The outcomes of this project will include advances in malaria drug development that build on Australian drug discovery efforts, seeding further funding opportunities from industry and other sources and contributing research training and capacity building in Australia.Read moreRead less

Drug targets in malaria parasites. Malaria is rampant throughout our Region and hinders the economies of our neighbours reducing regional prosperity and stability. Australian security and aid personnel deployed in the Region contract malaria infections and global warming could bring malaria-carrying mosquitoes south to Sydney.

Malaria is rampant throughout our Region and hinders the economies of our neighbours reducing regional prosperity and stability. Australian security and aid personnel deployed in the Region contract malaria infections and global warming could bring malaria-carrying mosquitoes south to Sydney. Australia is pre-eminent in malaria research, making lead discoveries in vaccine and drug development. However, we lack crucial resources to study the parasite in the mosquito phase of its life cycle. The Federation Fellowship will create a malaria mosquito facility to redress this crucial gap in our capability. The Fellowship will double as foreign aid investment by enhancing our capacity to protect ourselves as well as supporting our neighbours.Read moreRead less

The host specificity of bacterial pathogens. The vast majority of microorganisms that cause diseases in animals are host specific. In other words, they cause disease exclusively in a particular animal species, but are harmless for others. Despite considerable recent advances in our understanding of the mechanisms used by microorganisms in general to cause disease, in most cases the underlying basis of host-specificity is not known. In this project, we will use two animal pathogens, rabbit-spe ....The host specificity of bacterial pathogens. The vast majority of microorganisms that cause diseases in animals are host specific. In other words, they cause disease exclusively in a particular animal species, but are harmless for others. Despite considerable recent advances in our understanding of the mechanisms used by microorganisms in general to cause disease, in most cases the underlying basis of host-specificity is not known. In this project, we will use two animal pathogens, rabbit-specific enteropathogenic E. coli and the closely related bacterium, Citrobacter rodentium, which specifically infect rabbits and mice respectively, to investigate the molecular basis of host specificity.Read moreRead less
Functional genomics of large clostridial plasmids. The aims of this genomics project are to determine how large DNA elements called plasmids are able to be transferred between different strains of a bacterium that causes disease in domestic livestock. These plasmids carry genes that encode the potent protein toxins that are responsible for several diseases. To understand how these diseases are spread we must learn how the plasmids have evolved and whether they can move from bacterium to bacteriu ....Functional genomics of large clostridial plasmids.

These plasmids carry genes that encode the potent protein toxins that are responsible for several diseases. To understand how these diseases are spread we must learn how the plasmids have evolved and whether they can move from bacterium to bacterium. The successful completion of the project will result in a detailed understanding of genetic elements that are important mediators of several diseases of importance to Australian primary industry.Read moreRead less
Do cleaner-fish control infections of parasitic protozoa transmitted by gnathiid isopods and leeches? We will study a popular example of mutualism, cleaning behaviour, from a different point of view: that cleaner-fish control the parasitic protozoa of the blood of client-fish by eating their vectors. This will provide information on the biological control of vector-borne parasites and develop mathematical models that will help us understand the epidemiology of vector-borne parasites in the sea. ....Do cleaner-fish control infections of parasitic protozoa transmitted by gnathiid isopods and leeches?

This will provide information on the biological control of vector-borne parasites and develop mathematical models that will help us understand the epidemiology of vector-borne parasites in the sea. Our study will provide baseline data of a parasitic disease in a wild population, information useful for managing and monitoring the health of coral reefs. With the increased aquaculture of tropical fish species in Australia, this study will benefit the fish-farming industry by providing information on the biological control of fish parasites.Read moreRead less
