This trichrome-stained photomicrograph depicts a mature Entamoeba coli cyst containing five clearly visible nuclei and what may have been a sixth nucleus, which was outside the focal plane and, therefore, out of focus. The cyst also contained a visible chromatoid body.

Aug 11, 2023 · Entamoeba coli infection is caused by the ingestion of cysts of the parasite. The primary sources of contamination include: Contaminated water: Drinking water from contaminated sources, such as lakes, rivers, or improperly treated water supplies, can introduce Entamoeba coli cysts into the body.
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 may be seen in unstained as well as stained specimens.
This usually involves checking the cysts for the size, shape, and the number of nuclei. E. coli has cysts in size up to 10 to 35 micrometers, the shape is irregular, oval with a shell-like appearance that is more uniformed compared to E. histolytica, and has up to eight nuclei in the cyst compared to the four nuclei of E. histolytica.
