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
Conquering Schistosomiasis In China: The Last Mile

Summary
Schistosomiasis (Bilharzia), caused by Schistosoma bloodflukes, is an ancient disease in the People’s Republic of China (PRC). After decades of control, the Chinese authorities have slated their intention to eliminate the disease by 2020. However, current diagnostic methods underestimate the true infection rates so we contend this target is unattainable. Supplementation of current control measures with additional public health interventions will be required to achieve the goal of elimination.
Proteomic Approaches To Explore The Pathogenesis And Secretomes Of Parasitic Flukes Of Humans

Summary
Ten percent of the human population are at risk of infection with liver, blood and lung flukes. These parasites cause considerable human morbidity and mortality including a strong association with cancer of the bile ducts. Current control efforts rely on drugs, but, reinfection and resistance are a problem. This research is aimed at understanding how these parasites cause disease (particularly how a parasite causes cancer) and the development of vaccines and new drugs.
A Worm-free World: Defeating Parasitic Helminths Via Global Integrated Control

Funding Amount
$2,714,215.00
Summary
My research goal is to conquer parasitic worm infestations globally. These parasites cause substantial illness and affect the poorest people. Programs that drug-treat infected individuals are neither effective nor sustainable. My research has shown additional strategies, such as vaccination and health education, are needed. My goal is to develop and field test a combination of interventions in different settings leading to long-term control and elimination of these ancient human scourges.
Targeting Schistosome Calcium Signalling To Improve And Broaden Praziquantel Efficacy

Funding Amount

Summary
Schistosomiasis is caused by parasitic worms, treatment relies solely on praziquantel (PZQ). Schistosomes respond and recover from PZQ exposure through modulation of the gene CamKII. We will target this gene to both increase and extend the efficacy of PZQ in both adult parasites and in refractory juvenile parasites. Research will expand into assaying CamKII inhibitors to maximise effectiveness and take this work into animal models of this disease.

Summary
My research goal is to eliminate parasitic worm infestations globally. These parasites cause substantial illness and affect the world's poorest people. Programs that drug treat infected individuals operate but these are neither effective nor sustainable. Our research has shown that additional measures, such as vaccination and health education, are needed and we aim to develop and field test a combination of interventions that will lead to their sustainable control and eventual elimination.
A New Animal Model For Genitourinary Schistosomiasis

Summary
Schistosoma haematobium causes genitourinary schistosomiasis, a serious disease that affects reproductive health, urinary system health and potentially bladder cancer. This species is the most pathogenic species of all schistosomes, but comparatively less is know about it than other species because of a lack of a suitable model. We need a suitable model host for this important parasite. This project will test whether newborn pigs can be used as laboratory models.

Summary
I am a parasitologist researching the biology, immunology and epidemiology of human parasitic worms, particularly the schistosome bloodflukes and the hydatid tapeworms, which cause bilharzia and hydatidosis, diseases of the world’s poorest people that cause both major suffering and economic loss. My goal is to develop new methods, including vaccination, to control and eventually eliminate these parasites.
