Abstract

A total of 480 snails were collected from 3 habitats on the Mau Escarpment, Kenya, and were identified asBulinus tropicus. Of the 351 snails examined alive in London, 75 were infected withCalicophoron microbothrium, 39 withC. microbothrium andSchistosoma bovis, 1 withS. bovis. 24 with other species of trematodes and 212 were uninfected. Examination of digestive glands ofB. tropicus either uninfected or infected with bothC. microbothrium andS. bovis demonstrated that it is possible to differentiate between parasite and host enzyme activity using glucose phosphate isomerase. However, malate dehydrogenase enables a much clearer differentiation between the enzyme activity of the schistosome and that of the amphistome. Laboratory snail infection experiments demonstrated that it is possible successfully to infectB. tropicus withS. bovis if the snails have previously been exposed to miracidia ofC. microbothrium.
