Entamoeba histolytica is an anaerobic parasitic amoebozoan, part of the genus Entamoeba. [1] Predominantly infecting humans and other primates causing amoebiasis, E. histolytica is estimated to infect about 35-50 million people worldwide. [1] E. histolytica infection is estimated to kill more than 55,000 people each year. [2]

Life Cycle of Entamoeba histolytica. The human host ingests the

Entamoeba histolytica is well recognized as a pathogenic ameba, associated with intestinal and extraintestinal infections. Other morphologically-identical Entamoeba spp., including E. dispar, E. moshkovskii, and E. bangladeshi, are generally not associated with disease although investigations into pathogenic potential are ongoing.

Life cycle and pathogenicity of Entamoeba histolytica

Entamoeba histolytica is a protozoan that causes intestinal amebiasis as well as extraintestinal manifestations. Although 90 percent of E. histolytica infections are asymptomatic, nearly 50 million people become symptomatic, with about 100,000 deaths yearly. [1] Amebic infections are more prevalent in countries with lower socioeconomic conditions.

Entamoeba histolytica is an enteric protozoan parasite with worldwide distribution. It is responsible for amoebic dysentery (bloody diarrhea) and invasive extraintestinal amebiasis (such as liver abscess, peritonitis, and pleuropulmonary abscess).

Differences Between Entamoeba histolytica and Entamoeba coli

Protozoan species, genus Entamoeba. E. histolytica is morphologically similar to E. dispar, E. moshkovskii, and E. bangladeshi. Histolytic - histo + lyein (Greek) to loosen, trophozoites contain cytolytic and proteolytic enzymes, including collagenase and proteinases, and lyze neutrophils and macrophages. Cysts are ingested; excystation occurs.

Entamoeba histolytica. Entamoeba histolytica is one of a number of species of small amoebae which live in the alimentary canal of humans. These are usually harmless protozoa, feeding on bacteria and particles in the intestine. In certain conditions, entamoeba invades the wall of the intestine or rectum causing ulceration and bleeding, with pain.

Entamoeba histolytica

Amebiasis is defined as infection with Entamoeba histolytica, regardless of associated symptomatology. In resource-rich nations, this parasitic protozoan is seen primarily in travelers to and emigrants from endemic areas. Infections range from asymptomatic colonization to amebic colitis and life-threatening abscesses. Importantly, disease may occur months to years after exposure. Although E.

Wet mount. Entamoeba histolytica and Entamoeba dispar are morphologically identical species. In bright-field microscopy, E. histolytica/E. dispar cysts are spherical and usually measure 12 to 15 μm (range may be 10 to 20 μm). A mature cyst has 4 nuclei while an immature cyst may contain only 1 to 3 nuclei. Peripheral chromatin is fine.
