The nonpathogenic Entamoeba disparhowever, is morphologically identical to E. However, erthrophagocytosis is not typically observed on stained smears of E.

Transmission can also occur through exposure to fecal matter during sexual contact in which case not only cysts, but also trophozoites could prove infective. Trophozoites passed in the stool are rapidly destroyed once outside the body, and if ingested would not survive exposure to the gastric environment. Lanes 2 and 7: These cysts range in size from Peripheral chromatin is present and is often coarse and granular, and irregularly arranged along the nuclear membrane, but may be more uniform.


Antigen consists of a crude soluble extract of axenically cultured organisms. Several protozoan species in the genus Entamoeba colonize humans, but not all of them are associated with disease.

Notice the chromatoid bodies with blunt, rounded ends arrow. The trophozoites multiply by binary fission and produce cysts, and both stages are passed in the feces. As such, it is important to differentiate them from the morphologically-similar trophozoites of E. Life Cycle Cysts and trophozoites are passed in feces.
