Entamoeba coli is a parasitic amoeba that infects the intestines of humans. It is generally non-pathogenic and can be distinguished morphologically from Entamoeba histolytica, the parasite responsible for amoebic dysentary, by the number of nuclei present in the cyst stage: E. coli can have up to 8 nuclei in a mature cyst, whereas E. histolytica has only up to 4.

Pathology

E. Coli is a non-pathogenic amoeba that frequently exists as a commensal parasite in the human intestines. E. coli is important in medicine because it can be confused with E. Histolytica during microscopic examination of stool samples.

Life CycleEdit

Within the human intestine, the parasite is a trophozoite, or feeding stage parasite. The parasite forms resistant cysts which are passed in the feces. If these cysts are ingested (i.e. by consuming contaminated food or water), the cysts release trophozoites once they reach the intestine.
