Life cycle of liver worms (Fasciola hepatica)

Life cycle of  liver worms (Fasciola hepatica)

Information:

1. Sexual reproduction Fasciola hepatica produce eggs in the liver and then move through the bloodstream to the bile     and gut,             and then come out with feces.

2. The eggs hatch and grow into ciliated mirasidium in a wet place.

3. Mirasidium infects the intermediate host, Lymnaea or water snail.

4. Mirasidium turns into sporocyst in the body of the intermediate host (water slug).

5. Sporocists develop asexually into redia.

6. Redia metamorphoses into cercariae. This cercariae escapes from the body of the snail and attaches to turmbuhan or water           grass.

7. Sercaria forms young worms or metacercariae.

8. Metacercariae are eaten by animals and then become adult worms in the liver.
