Parasite of the Month



Diplogonoporiasis

Diplogonoporus grandis is one of human broad tapeworms residing in intestinal track. Normally this tapeworm is a parasite of sea animals such as whales, but reported from more than 200 Japanese patients in Japan. As far as I am concerned, no patient is reported from the outside of Japan. If you have a case like this or if you breed this worm in your intestine, please let me know.
