Simple demonstration of Diphyllobothrium latum life cycle.
D. latum is one of the fish-borne parasitic infections that's common especially in the Far East.
The infection is mainly transmitted after the ingestion of raw or undercooked Salmon fish containing the infective stage (Plerocercoid larvae).
The worm is one of the cestodal worms with a length that could reach 10 meters, hence, the infection could potentially lead to Intestinal obstruction in the infected human host. [1]
