Entamoeba coli, E. hartmanni, E. polecki, Endolimax nana, and Iodamoeba buetschlii are generally considered nonpathogenic and reside in the lumen of the large intestine in the human host. Both cysts and trophozoites of these species are passed in stool and are considered diagnostic .

The trophozoite is 10 to 60 µm in diameter, ameboid, actively motile, and often erythrophagocytic. In stained specimens, the nucleus has a central karyosome with finely beaded peripheral chromatin. The cyst form is rounded, 10 to 20 µm in diameter, with one to four nuclei showing the characteristic appearance.
