Description:This trichrome-stained photomicrograph depicts an Entamoeba histolytica trophozoite, within which a number of erythrocytes can be seen as dark inclusions.
Erythrophagocytosis, which is the ingestion of red blood cells into the parasite’s cytoplasm, is the only characteristic that can be used to differentiate morphologically E. histolytica from the nonpathogenic E. dispar.

Several protozoan species in the genus Entamoeba colonize humans, but not all of them are associated with disease. Entamoeba histolytica is well recognized as a pathogenic amoeba, associated with intestinal and extraintestinal infections. The other species are important because they may be confused with E. histolytica in diagnostic investigations.
