Field studies of a reusable polyamide filter for detection of Schistosoma haematobium eggs by urine filtration

Tropenmed Parasitol. 1982 Dec;33(4):227-8.


A reusable monofilament polyamide (Nytrel) filter and ninhydrin stained paper filter were compared in syringe filtration of urine to detect Schistosoma haematobium eggs in the urine under field conditions. The sensitivity of the technique using the Nytrel filter was similar to that of ninhydrin stained paper filters. The quantitative geometric mean S. haematobium egg counts obtained with the Nytrel filter were similar to those obtained with the paper filter.
