Clinical Findings

Clinical findings vary considerably. The main findings are:

  • Asymptomatic amoebiasis (healthy cyst passers)
  • Chronic amoebiasis with diarrhoea, and sometimes mucus
  • Acute amoebiasis with dysentery and fever

More rarely: amoebic granulomata (in the wall of the large intestine) – often misdiagnosed as carcinoma – and ulceration in the perianal region

  • Extra-intestinal amoebiasis: dissemination in the bloodstream produces liver abscesses, and occasionally abscesses of the lung and brain.
