Overview of Endamoeba coli
Amoebiasis is defined as infection with the protozoan parasite Entamoeba histolytica. However there are several Endamebas species which are closely related to E. histolytica such as E. dipar and E. coli. [1]
Entamoeba coliare a non-pathogenic species of Entamoeba that frequently exists as a commensal parasite in large intestine of the human. Both cysts and trophozoites of the species are passed in stool and considered diagnostic [2]. Cysts are typically found in formed stool, whereas trophozoites are typically found in diarrheal stool. Colonization of the nonpathogenic amebae occurs after ingestion of mature cysts in fecally-contaminated food, water, or fomites [2].
Summary of data
Rendtorff, R. C. (1954) studied the Entamoeba coli exposure to human volunteers with a known numbers of cysts of E. coli were administered orally in capsules to volunteers to determine numbers of parasites necessary to establish the infection.
