Small intestinal fluke found in the Nile, SE Asia and the far East. It is an echo-y kind of organism. It takes up residence in the small bowel. Look for eggs in the stool but the eggs are indistinguishable from those of Metagonimus yokogawai, Clonorchis and Opisthorchis.

Epidemiologic Risks

Eating contaminated raw freshwater fish.


Abdominal pain with eosinophilia and diarrhea. Sometimes the organism spreads outside the bowel.
