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.

Aug 23, 2023 · Entamoeba coli is one of many non-pathogenic protozoa found in humans.[1] It is transmitted through fecal-oral contact, and the mature cyst can be found in contaminated water.[2] Typically, these protozoa inhabit the large intestinal tract and can be identified in diagnostic stool specimens.[3] It is essential to differentiate Entamoeba coli, a nonpathogenic protozoan, from those that cause ...

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.

This trichrome-stained photomicrograph, depicted a mature, Entamoeba coli cyst, containing five, clearly visible nuclei, and a 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. High Resolution: Click here for hi-resolution image (34.02 MB)
