Abstract
The survey and mass-teratment of helminthic infections with pyrantel pamoate was carried out on 140 school children in Ile-Ife, Western State of Nigeria. It was marked that 129 children were positive for Ascaris lumbricoides (As. lumbricoides), Trichuris trichiura (Tr. trichiura) or Necator americanus (Ne. americanus). Of the parasitepositive children, 82 could be allocated for the treatment with pyrantel pamoate. They were divided on the basis of having single, double or triple infections of the following intestinal nematodes; As. lumbricoides, Tr. trichiura and Ne. americanus.
The results demonstrate that pyrantel pamoate is effective in curing As. lumbricoides almost completely, but is less effective against Tr. trichiura and Ne. americanus
