Entamoeba coli is one of many non-pathogenic protozoa found in humans. They are quite small, 20-35m and have a simple life cycle that consists of an infective cyst stage (shown below) and a multiplying Trophozoite stage (shown above). Entamoeba coli, E. hartmanni, E. polecki, Endolimax nana, and Iodamoeba buetschlii are generally considered nonpathogenic and reside in the large intestine of the human host. Annals of parasitology.
