Life Cycle of Cyathocotyle caecumalis sp. nov

This article has firstly reported the life cycle of Cyathocotyle caecumalis sp.nov and confirmed that Parafossarulus striatulus and Misgurnus auguillicaudatus served as the first and second intermediate host of C.caecumalis sp.nov, respectively.At room temperature of 20-28℃, miracidiia hatched from eggs after 21days of incubation and developed into sporocyst in the snail host, It was found that cercaria emerged from the snail host after 62days.Metacercariae may encysted on the surface or within the muscle of loach 10days later.Ducks infected with metacerariae orally ovulated the mature eggs in the feces 3days later.The total life cycle of C.caecumalis sp.nov lasted 96days.
