Field studies of a rapid accurate means of quantifying Schistosoma haematobium eggs in urine samples

摘要

A new means of quantifying schistosome eggs has been adapted from the laboratory to the field. Urine from 510 individuals in areas of Kenya with a high prevalence of schistosomiasis haematobia was injected in aliquots of 10, 5 and 1 ml on to transparent Nuclepore filters, 13 mm in diameter. The filters were placed face down on glass slides and were read without staining at ×40 magnification. The method has been shown to be accurate, sensitive, and reproducible, and also extremely rapid.
