This technique makes use of a new type of monofilament polyamide filter Nytrel-TI, with a pore size of 40 mum, allowing filtration of turbid water without clogging of the filter. A three-level prefiltration column (1000, 500 and 200 mum), which retains organisms larger than cercariae, facilitates reading of the filter. The apparatus used weighs less than 3.5 kg; it requires no power supply and can easily be used in the field.}, keywords = {*Water, Animals, Filtration/instrumentation/methods, Schistosoma/*isolation \& purification, Water Supply}, isbn = {0042-9686 (Print)
