Aug 23, 2023 · HHS. USA.gov. 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]

Diagnosis of Entamoeba coli Infection: To diagnose Entamoeba coli infection, the following steps may be taken: Stool examination: A stool sample is collected and examined under a microscope to detect the presence of Entamoeba coli cysts or trophozoites. Multiple samples may be required to increase the chances of detecting the parasite.
This photomicrograph of a trichrome-stained specimen revealed the presence of an Entamoeba histolytica trophozoite, within which a number of phagocytized erythrocytes could be seen as dark, round inclusions.
Cysts and trophozoites are passed in feces . Cysts are typically found in formed stool, whereas trophozoites are typically found in diarrheal stool. Infection with Entamoeba histolytica (and E.dispar) occurs via ingestion of mature cysts from fecally contaminated food, water, or hands. Exposure to infectious cysts and trophozoites in fecal ...
In this focal plane, the smaller Entamoeba histolytica cyst (top), contained four nuclei, and two bluntly-tipped chromatoid bodies, while six nuclei could be detected in the larger Entamoeba coli cyst (bottom), which also contained two chromatoid bodies as well.
