Studies on the fresh water Cercariae in Leyte Island, Philippines. 2. Cercariae from Oncomelania quadrasi.

From 1975 to 1976, more than six thousand snails of Oncomelania quadrasi were observed for cercarial fauna in the north-eastern part of Leyte Island, Philippines. Altogether, six species of cercariae including that of Schistosoma japonicum were found, namely two furcocercariae, one monostome cercaria, two xiphidiocercariae and one tail-less cercaria. In this paper a description of their morphology, infection rate, locality, and some remarks on the presumptive life cycle is included with illustrations and photographs.
