Question

Quizplus · Accepted Answer

The life cycle of the Chinese liver fluke (Clonorchis sinensis) starts with the adult fluke laying eggs (shelled embryos) that are passed out of the host. These eggs hatch into miracidia, which then infect a suitable snail intermediate host. Inside the snail, the miracidium develops into a sporocyst, which gives rise to rediae, and then cercariae. The cercariae leave the snail and infect a fish, where they encyst as metacercariae. When the infected fish is consumed by a definitive host (including humans), the metacercariae develop into adult flukes, completing the cycle.
