Out of the 39 various waterbodies studied, 31 (79,5%) harboured different species of freshwater snails. The six snail species collected were Pila ovata (Olivier), Bulinus forskali (Ehrenberg), B. globosus (Morelet), Lymnaea natalensis Krauss, Segmentorbis angustus (Jickeli) and Lanestes libycus (Morelet). Two snail species, L. natalensis and B. forskali, shed furcocercous and gymnocephalous cercaria respectively. The overall snail infection rate was 7.6%.
