How is Entamoeba identified in histological samples?
In histological samples, Entamoeba can be identified by its morphology. Under the microscope, trophozoites of Entamoeba histolytica appear as round to oval cells with a size ranging from 15 to 60 micrometers. They have a characteristic nucleus with a central karyosome and fine peripheral chromatin. The presence of ingested red blood cells within the cytoplasm is a distinguishing feature of E. histolytica.
