1) The trophozoites multiply by binary fission and produce cysts and both stages are passed in the faeces.
2) Trophozoites migrate to the large intestine.
3) Excystation occurs in the small intestine and trophozoites are released.
4) Infection by Entamoeba histolytica occurs by ingestion of mature cysts in fecally contaminated food, water, or hands.
