An epidemiological survey to characterize Entamoeba histolytica/E. dispar isolates from 123 human subjects was carried out in the Wonji area of Central Ethiopia, where an increased incidence of amoebic infection has been reported. In a randomized, coproparasitological study, 93 (75.6%) of the subjects were found positive for at least one species of intestinal parasite: 14 (15.1%) harboured only one species and 79 (84.9%) were infected with at least two species. In-vitro culture in Robinson's medium revealed amoebic parasites in 52 (82.5%) of the 63 cases tested. Of the 29 amoebic isolates successfully stabilized, cloned and characterized by Sargeaunt's electrophoretic technique, 25 (93.1%,) were of E. dispar zymodemes (19 of zymodeme I, two each of zymodemes III, V and XI, and one each of zymodemes X and XV) and two (6.9%) were of E. histolytica (zymodeme XIII).
