Question

Name the two intermediate Host on which the human liver fluke depends to complete its life cycle so as to facilitate parasitization of its primary host?

Answer 1

Dear student,


The intermediate host of liver fluke is snail and the primary host is vertebrate (sheep, human etc). The first larval stage is miracidium which enters the intermediate host (snail). Primary host is infected by metacercaria. Cercaria covered by cyst is called metacercaria which is present on grasses and is engulfed by sheep (primary host).

Regards.
