Vedclass · Answer

(A) The life cycle of the liver fluke ($Fasciola$ $hepatica$) involves two hosts.$1$. The primary host is a sheep or human (vertebrate),and the intermediate host is a snail (mollusc).$2$. The $Miracidium$ larva infects the intermediate host (snail) to continue its development.$3$. After passing through various stages ($Sporocyst$,$Redia$,$Cercaria$) within the snail,the $Cercaria$ larvae emerge and encyst on aquatic vegetation to form the $Metacercaria$ stage.$4$. The $Metacercaria$ is the infective stage for the primary host (sheep/human) when ingested with vegetation.Therefore,the liver fluke infects the intermediate host as a $Miracidium$ and the primary host as a $Metacercaria$.

During its life cycle,the liver fluke ($Fasciola$ $hepatica$) infects its intermediate host and primary host,respectively,through which of the following larval stages?
