E. histolytica belongs to thegenus Entamoeba, along with 5 other parasites: E. coli, E. hartamanni, E. dispar, E. gingivalis, and E. polecki.However, only E. histolytica causes Amebiasis.mebiasis is a disease caused by Entamoeba histolytica, a unicellular eukaryotic parasite.

Entamoeba histolytica is an anaerobic parasitic protozoan, part of the genus Entamoeba. Predominantly infecting humans and other primates, E. histolytica is estimated to infect about 50 million people worldwide.Previously, it was thought that 10% of the world population was infected, but these figures predate the recognition that at least 90% of these infections were due to a second species, E. dispar.he active (trophozoite) stage exists only in the host and in fresh loose feces; cysts survive outside the host in water, in soils, and on foods, especially under moist conditions on the latter. The cysts are readily killed by heat and by freezing temperatures, and survive for only a few months outside of the host.
