Intestinal fluke infection

Fasciolopsis buski


Fasciolopsis buski is a large intestinal trematode or fluke (length up to 7 cm).


Life cycle of Fasciolopsis buski


Undeveloped large eggs are passed in the faeces. Miracidia develop outside the host within the egg and – after hatching – have to find their snail intermediate host in which further development to cercariae takes place. Cercariae leave their snail host and attach to water plants where they encyst to metacercariae. Those are taken up orally by animals and humans. In the final host, metacercariae excyst in the intestine and develop into adult flukes.
