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]

Entamoeba coli . E. coli cysts in concentrated wet mounts. Cysts of Entamoeba coli are usually spherical but may be elongated and measure 10–35 µm. Mature cysts typically have 8 nuclei but may have as many as 16 or more. Entamoeba coli is the only Entamoeba species found in humans that has more than four nuclei in the cyst stage. The nuclei ...
Aug 23, 2023 · Entamoeba coli is one of many non-pathogenic protozoa found in humans. It is transmitted through fecal-oral contact, and the mature cyst can be found in contaminated water. Typically, these protozoa inhabit the large intestinal tract and can be identified in diagnostic stool specimens. It is essential to differentiate Entamoeba coli, a ...
Entamoeba species all come in monogenetic forms, or having one generation lifecycles. E. coli has "three distinct morphological forms exist airing the life cycle-Trophozoite, Pre-cystic stage and Cystic stage". This lifecycle gives rise to the general way of how Entamoeba species form.

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.
The cysts and trophozoites of E. coli can be distinguished from those of the pathogenic E. histolytica on the basis of nuclear morphology and cyst size. Whereas E. histolytica cysts usually have fewer than five nuclei and are 10–15 µm in diameter, the cysts of E. coli are greater than 15 µm and often have five to eight nuclei. 179–181
