Approximately 10-20 μm in diameter
- Entamoeba cells are small, with a single nucleus and typically a single lobose pseudopod taking the form of a clear anterior bulge. They have a simple life cycle. The trophozoite (feeding-dividing form) is approximately 10-20 μm in diameter and feeds primarily on bacteria. It divides by simple binary fission to form two smaller daughter cells.

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.
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 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.
Trophozoites passed in the stool are rapidly destroyed once outside the body and, if ingested, would not survive exposure to the gastric environment. Hosts. Humans are considered the main host for all of the discussed species except for Entamoeba polecki, which is usually associated with primates and swine. Geographic Distribution.
The trophozoite is the actively metabolizing, mobile stage, and the cyst is dormant and environmentally resistant. Diagnostic concern centers on both stages ( Fig. 79-3 and Table 79-2 ). Trophozoites vary remarkably in size-from 10 to 60 µm or more in diameter, and when they are alive they may be actively motile.

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 ...
The trophozoites of E. coli can be distinguished by their broad and conical pseudopods. They are generally confused with E. histolytica due to their overlap in size. Cysts are distinguished by the presence of eight nuclei found in the mature form. For the diagnosis of E. coli, a stool sample is usually tested.
