[Histopathology of experimental hepatic amebiasis]

The method of intrahepatic inoculation was successfully used to establish an experimental model of hepatic amebiasis in golden hamsters for studying its pathological morphology. Three types of macroscopic liver lesions, i.e., isolated abscess, multinodular abscess and ruptured lesion were described. On light microscopy the alteration and the proliferation type lesions were found as distinct pathological characteristics of the early and advanced hepatic amebiasis respectively. The development pattern of hepatic amebiasis and the pathogenicity of Entamoeba histolytica were discussed.
