| Abstract: | Severe diarrhea in a female outpatient was caused by an intestinal fluke, identified as Heterophyes heterophyes, a natural parasite of humans and domesticated and wild fish-eating mammals. This parasite is endemic in the Orient and the Middle East. A detailed case history revealed that the woman had never traveled outside the continental United States but became infected while eating raw fresh-water fish (sushi) that had been served at a local Japanese restaurant. The restaurant specialized in serving a great variety of fresh-water and salt-water fish that were flown in from the Orient and other parts of the world. The authors' findings indicate that a person does not have to travel to an endemic area to become infected with this organism. |
