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.
Aug 23, 2023 · 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.
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. The nuclei may be seen in unstained as well as stained specimens.
