Schistosomiasis is a severe infectious disease caused by parasitic worms. As an intermediate host, freshwater snails play a central role in the life cycle of the parasite. In a recent study published in the journal Scientific Reports, researchers from the Helmholtz Centre for Environmental Research (UFZ) in cooperation with the Kenya-based International Centre of Insect Physiology and Ecology (icipe) succeeded in proving that snail populations in waterbodies contaminated with pesticides were significantly larger than in uncontaminated waterbodies. The pesticides used in agriculture may well be an outright driver for the risk of infection with schistosomiasis, the researchers warn.
