Entamoeba histolytica and another ameba, Entamoeba dispar, which is about 10 times more common, look the same when seen under a microscope. Unlike infection with E. histolytica, which sometimes makes people sick, infection with E. dispar does not make people sick and therefore does not need to be treated.
Entamoeba histolytica and Entamoeba dispar are morphologically identical species. In bright-field microscopy, E. histolytica/E. dispar cysts are spherical and usually measure 12 to 15 μm (range may be 10 to 20 μm). A mature cyst has 4 nuclei while an immature cyst may contain only 1 to 3 nuclei.
