Oct 6, 2022 · Life cycle of Entamoeba histolytica has two-stage: motile trophozoite and non-motile cyst. Trophozoites are found in intestinal lesions, extra-intestinal lesions, and diarrheal stools whereas cyst predominates in non-diarrheal stools.
Dec 2, 2018 · Entamoeba histolytica is an invasive enteric protozoan [ 1, 2, 10 ].

Excystation occurs in the small intestine with the release of motile trophozoites, which migrate to the large intestine.
Nov 22, 2023 · Intestinal amebiasis is caused by the protozoan Entamoeba histolytica. There are four species of intestinal amebae with identical morphologic characteristics: E. histolytica, E. dispar, E. moshkovskii, and E. bangladeshi [ 1,2 ]. Most symptomatic disease is caused by E. histolytica; E. dispar is generally considered nonpathogenic.
Feb 13, 2017 · Entamoeba histolytica is a unicellular, protozoon parasite of humans. It moves by a jelly-like tongue-like protrusion of the cytoplasm “pseudopodium.” Infection with E. histolytica may be the cause of a variety of symptoms, beginning from no symptoms to severe fulminating intestinal and/or life-threatening extraintestinal disease.
Nov 12, 2020 · E. histolytica is the causative agent of the diarrheal disease known as amebiasis, but it can sometimes penetrate the intestinal wall, enter the circulation, and cause abscesses throughout the body, most commonly in the liver. E. histolytica has 2 main stages during its life cycle: the trophozoite and the cyst stage.
