»Alison Schroeer DescriptionThis biological illustration was created by scientific illustrator Alison Schroeer of Schroeer Scientific Illustration. It shows the life cycle or lifecycle of the Chinese liver fluke, or Oriental liver fluke, Clonorhics sinensis, in the class Trematoda, phyla Platyhelmenthis. This species of worm parasite is very common.
Human hosts pass out liver fluke eggs which are eaten by snails, develop into miracidium, then sporocyst, then redia which reproduce asexually and bore out of the snail. As free-swimming cercariae, they reproduce asexually and bore through the skin of the host fish to live on its muscles. When infected fish are eaten by humans, the liver fluke becomes a mature adult inside the bile duct and gall bladder of the human liver. Eggs leave the human in feces, and the cycle begins again.
