[Land molluscs--intermediate hosts of trematodes of the family Microphallidae travassos, 1920].
Encysted metacercariae of Microphallus sp. were found in the land mollusks Bradybaena duplocincta and Jaminia potaniniana asiatica collected on the slopes of Tien-Shan. The above mollusks are first reported as intermediate hosts of microphallids. The meta cercariae found were fed to white mice, golden hamsters, chickens and nestlings of sparrows and starlings. Maritae developed only in white mice and golden hamsters. Mature trematodes containing 14 to 35 eggs in the uterus were found in the small intestine 66-90 hours after the infection. Small mammals are assumed to be the definitive hosts of these trematodes. The trematodes of Microphallus sp. are characterized by a short life cycle with one intermediate host, land mollusk.
