Answer to Case 333

Answer:  Diphyllobothrium sp. (broad fish tapeworm)

The diagnosis is made by identification of key morphologic characteristics including the broad proglottids with small central uterine structure (arrow) and oval-shaped 65-micron eggs.


Although we can't easily make out the operculum on the egg shown, the abopercular knob (arrow) is visible.
