Summary
There is an urgent need to develop new drugs to treat malaria, one of the most important diseases to afflict humanity. We have developed new analytical approaches for measuring parasite metabolism while they live inside host cells. These approaches will be used to identify metabolic pathways that are essential for parasite infectivity and to understand the mode of action of new classes of antimalarial compounds
One third of the world's population is infected with the protozoan parasite, Toxoplasma gondii, which can cause life-threatening infections. This proposal will utilize new analytical technologies to understand how these parasites are able to survive in a wide variety of different host cells, how they manage to persist within brain and muscle tissue for the life of the patient and how infection may be linked to mental health disorders, such as schizopohrenia.

Summary
Efforts to control malaria in endemic areas are very often thwarted by "carriers", who have transmissible parasites in their bloodstream (called gametocytes), but who suffer no symptoms. These gametocytes serve as a reservoir ready to reinitiate disease transmission when mosquito numbers increase. This project will develop urgently needed strategies to target gametocytes, and thus block malaria transmission.

Summary
Culturing the parasite that causes malaria in the laboratory is essential for research. Variations in how the parasites are cultured will be investigated for their effect on the parasite. We are particularly interested in how different conditions affect the parasites’ response to malaria drugs. By understanding how environmental parameters impact on the parasites and their response to anti-malarial drugs, we will improve our understanding of drug resistance to malaria, thus design better drugs.
Targeting Toxoplasma Gondii Latent Stages Responsible For Chronic Disease

Summary
Many microbial pathogens become resistant to host immune response and drugs by entering a slow-growing, dormant state. These stages are commonly responsible for long term, chronic infections. We will investigate the molecular basis of dormancy in Toxoplasma gondii, which infects one in three people. These studies will identify metabolic pathways that are essential for dormancy with the view of developing new therapies for treating long term, recurrent infections.
Identifying Metabolic Pathways In Leishmania Parasites And Their Host Cells Required For Virulence

Summary
Our lack of understanding of microbial metabolism in infected animal tissues has hindered the development of effective therapies. This is particularly true for many parasitic diseases, including Leishmania spp that cause devastating disease throughout the tropics. We will utilize a range of innovative analytical and genetic approaches to identify metabolic pathway in Leishmania parasites and infected host cells that are required for virulence and are potential drug targets.
