ABSTRACT
Subspecies of Oncomelania hupensis were exposed to infection with zoophilic and anthropophilic strains of Schistosoma japonicum. The snails were Philippine O. h. quadrasi from the islands of Bohol, Leyte and Mindanao, O. h. formosana from Changhua and Ilan, and O. h. chiui from Taiwan, O. h. hupensis from China, O. h. nosophora from Japan and O. h. lindoensis from Indonesia. Anthropophilic strains of S. japonicum were from Bohol and Leyte in the Philippines, China, Japan and Indonesia. The zoophilic strains were from Changhua and Ilan, Taiwan. All geographic strains of the parasite developed exceptionally well and produced cercariae in 32-50% of O. h. chiui and 5-43% of the natural snail hosts. Development in other subspecies of snails with geographic strains of the parasite were variable. Only a few O. h. formosana (Changhua) could be infected with the parasites from other geographic areas and only one O. h. quadrasi each from Mindanao became infected with the Bohol and Changhua strains of S. japonicum.
