E. coli trophozoites can be distinguished by their wide and tapered pseudopodia. They are often mistaken for E. histolytica due to their overlap in size. The cysts are distinguished by noticing the eight nuclei found in the mature form. To diagnose for E. coli, a stool sample is usually tested.

Entamoeba coli Introduction Entamoeba coli is a non-pathogenic amoeba with world wide distribution. Its life cycle is similar to that of E. histolytica but it does not have an invasive stage and do not ingest red blood cells. Morphology of Cysts Cysts of E. coli are 15 - 30 in diameter and contain 1 - 8 nuclei. Chromatoid bodies are not
Entamoeba species exist in 2 forms: Trophozoite. Cyst. The motile trophozoites feed on bacteria and tissue, reproduce, colonize the lumen and the mucosa of the large intestine, and sometimes invade tissues and organs. Trophozoites predominate in liquid stools but rapidly die outside the body and, if ingested, would be killed by gastric acids.
