title: [The importance of Entamoeba histolytica in persons returning from the tropics].
abstract: Stools from 1000 travellers returning from the tropics were examined for intestinal parasites. The most frequently isolated intestinal pathogens were Giardia lamblia (5%) and E. histolytica (3.6%). For 21 out of 36 E. histolytica isolates iso-enzyme differentiation by starch-gel electrophoresis was possible, yielding a pathogenic pattern in four. This finding correlated closely with clinical symptoms and positive serology, while E. histolytica with non-pathogenic zymodeme should not be considered as a cause of diarrhoea.
