Patients may rarely show gastrointestinal symptoms such as loose stools, colicky abdominal pain, and flatulence. [2] A single nucleus lies inside the endoplasm. Usually, the amoeba is immobile, and keeps its round shape. ; The cystic form changes into trophozoites . [3]It is essential to differentiate Entamoeba coli, a nonpathogenic protozoan, from those that cause significant disease. Entamoeba coli is transmitted through fecal-oral contact. Its life cycle is similar to that of E. histolytica but it does not have an invasive stage and does not ingest red blood cells.

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. Both cysts and trophozoites of these species are passed in stool and are considered diagnostic . However, there are some kinds of E. coli that are harmful and can cause disease. The pre-cyst form begins when the trophozoite starts to slightly change its shape, becoming more spherical and containing two nuclei. [3] Trophozoites found in the stool outside the body are rapidly destroyed, and if ingested, would not survive exposure to the gastric environment.
