Entamoeba coli cysts
- E. coli cysts stained with trichrome. Cysts of Entamoeba coli are usually spherical, but may be elongated, and measure 10 to 35 µm. Mature cysts typically have 8 nuclei but may have as many as 16 or more. Entamoeba coli is the only species in the genus encountered in humans with more than four nuclei in the cyst stage.

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 histolytica . 
Nov 7, 2022 · 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 nonpathogenic protozoan, from those that cause significant disease.
Entamoeba coli, E. hartmanni, E. polecki, Endolimax nana, and Iodamoeba buetschlii are generally considered nonpathogenic and reside in the large intestine of the human host . Both cysts and trophozoites of these species are passed in stool and considered diagnostic . Cysts are typically found in formed stool, whereas trophozoites are typically found in diarrheal stool.
