SURVEY OF INTERMEDIATE SNAIL HOSTS OF HUMAN SCHSTOSOMES IN RE-SE1TLEMENT SITES OF WESTERN ETHIOPIA

Abstract

ABSTRACT From 29 January to March 1985, a field survey for the snail ,.ntermediate hosts of human schistosomes was conducted in 252 water bodies in 141 re-settlement sites in Wollega, Illubabor and Kafa Administrative Regions. Biomphalaria pfeifferi, the snail intermediate host for schistosoma mansoni, was collected from three water bodies in Wollega and from one water source in Kafa. The settlers in the re-settlement sites consisted of people from intestinal schistosomiasis endemic zones in the north. The habitats infested with Biomphalaria pfeifferi therefore need to be considered since they are potential foci for the establishment of the disease.
