Occurs worldwide but is endemic in Africa, Mexico, Central and South America. It is caused by a single cell parasite which is contracted from ingestion of contaminated water.

Most commonly presents as a non invasive disease with abdominal bloating, cramps and diarrhoea. A course of 2Gms tinadazole for 3 days (or high dose metronidazole) usually suffices.

The more serious forms can invade the bowel (bloody diarrhoea, perforation, toxic megacolon) and/or spread to the liver causing an abscess. Serology and imaging usually are required.
