Abstract

Three autochthonous cases of Entamoeba histolytica infection in institutionalized mentally-retarded patients are reported. Isoenzyme analysis by starch-gel electrophoresis shows the pathogenicity of the three isolates: two belong to zymodeme II, and one to zymodeme XIX. The study shows that invasive E. histolytica strains occur in Italy and can be isolated from institutionalized oligophrenic patients.
