Abstract

The cattle liver flukes were collected at daughter house and classified with gross morphology. The hepatica type was only 14 flukes (4.7%) and the gigantica type was 284 flukes (95.3%) among total 298 flukes collected. In order to determinate the intermediate host of the flukes, artificial infection with the miracidia to snail hosts, Radix auricularia and Austropelea ollula, were successfully carried out, but the development in the later was terminated at the sporocyst stage. Intermediate host of the cattle flukes used to hibernate in deep part of the stubbles of rice pady. The number of A. ollula that has been collected from a rice stubble was ranged 0 to 19. Their mean number was 7 snails per the stubble. In artificial infection with miracidia, the reasonable number of them were 1 to 9 and the snail size was 2 to 5mm in length. The productivility of metacercaria in the intermediate host was observed. The metacercarial production per snail was ranged 5.5 to 48.0 per one miracidium.
