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, 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 .

Cysts and trophozoites are passed in feces . Cysts are typically found in formed stool, whereas trophozoites are typically found in diarrheal stool. Infection with Entamoeba histolytica (and E.dispar) occurs via ingestion of mature cysts from fecally contaminated food, water, or hands.
Entamoeba coli has a worldwide distribution and is one of the most commonly reported Entamoeba species in clinical specimens. Non-human primates may serve as reservoir hosts. Trophozoites of E. coli measure 15–50 μm and have a single nucleus with irregular peripheral chromatin and a usually eccentric karyosome.
Aug 23, 2023 · Entamoeba coli, similar to other Entamoeba specifies, has three distinct morphological forms: trophozoite, pre-cystic stage, and cystic stage. The trophozoite form, which measures 20 to 25 μm, is minimally mobile. [23]
