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.
Schistosomiasis is one of the world's most serious and prevalent diseases affecting nearly 200 million people world-wide. It is currently treated with a single drug, though there is growing concern about the development of resistance to it. In this proposal we will explore whether a new cellular pathway involving the cell death machinery we have identified in the disease-causing parasites could provide a possible target for the development of new treatments against schistosomiasis.
Genome-based Tools To Support Urogenital Schistosomiasis Control

Summary
More than 100 million sub-Saharan Africans have urogenital schistosomiasis, a disease that promotes malignant cancer and HIV/AIDS. Control depends on a single drug, making resistance an imminent threat. We will deliver new molecular tools to assess parasite genetic diversity and to prioritise a panel of anti-parasitic drug targets and vaccine candidates. These outcomes will deliver the next generation of interventions against urogenital schistosomiasis.
Targeting Schistosome Calcium Signalling To Improve And Broaden Praziquantel Efficacy

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.
Somatic Gene Trapping In Schistosoma Mansoni _ The Key To Functional Analysis

Summary
Blood flukes are endemic in 76 countries and infect 300 million people worldwide. Control largely relies on the drug praziquantel. However, its wide scale use has led to concerns that drug resistance will develop. In this study we will use ñgene trap vectorsî to introduce insertional mutations into the schistosome genome. This will help to understand the function and importance of genes in biochemical pathways used by the parasite and to define effective targets for drug and vaccine development.
Schistosomiasis is a major public health problem in the Philippines with approximately 6.7 million people at risk of infection. Mass human chemotherapy has formed the cornerstone of control for decades but has failed to control the disease. Transmission reduction is a key step towards elimination and integrated interventions should target both definitive and intermediate host transmission pathways. We propose to trial integrated control strategies for the disease and expect the outcomes to have ....Schistosomiasis is a major public health problem in the Philippines with approximately 6.7 million people at risk of infection. Mass human chemotherapy has formed the cornerstone of control for decades but has failed to control the disease. Transmission reduction is a key step towards elimination and integrated interventions should target both definitive and intermediate host transmission pathways. We propose to trial integrated control strategies for the disease and expect the outcomes to have broader implications for Southeast Asia.Read moreRead less

Summary
With the increasing occurrence of the debilitating tropical disease schistosomiasis due to climate change, novel therapeutics are in demand. Current therapies rely on treatment with a single drug, and require repeated application. In this timely study, we will elucidate the role of surface-associated proteins, hypothesised to be the crucial stabilising factor in the body wall of the blood-feeding worm schistosome that protects the parasite. Targetting these proteins will lead to new therapeutics ....With the increasing occurrence of the debilitating tropical disease schistosomiasis due to climate change, novel therapeutics are in demand.
