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 is a non-pathogenic species of Entamoeba that frequently exists as a commensal parasite in the human gastrointestinal tract. E. coli (not to be confused with the bacterium Escherichia coli ) is important in medicine because it can be confused during microscopic examination of stained stool specimens with the pathogenic Entamoeba ...

Trophozoites of E. coli measure 15–50 μm and have a single nucleus with irregular peripheral chromatin and a usually eccentric karyosome. The cytoplasm is often described as “dirty” and may contain vacuoles and ingested food particles, including bacteria, yeast, and even other intestinal protozoa. Cysts are 10–35 μm in diameter.
Molecular methods are currently recommended for distinguishing pathogenic Entamoeba species. Microscopic Detection. Microscopic identification of cysts and trophozoites in the stool is the common method for diagnosing pathogenic Entamoeba species. This can be accomplished using:
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.
