Several protozoan species in the genus Entamoeba colonize humans, but not all of them are associated with disease. 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 gen...
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 matter d...
Pathogenic Entamoeba species occur worldwide and are frequently recovered from fresh water contaminated with human feces. The majority of amebiasis cases occur in developing countries. In industrialized countries, risk groups include men who have sex with men, travelers, recent immigrants, immunocompromised persons, and institutionalized population...
Learn about Entamoeba histolytica, a pathogenic ameba that causes intestinal and extraintestinal infections. See images of cysts and trophozoites, life cycle, and laboratory diagnosis methods.
Life-cycle of Entamoeba histolytica. Entamoeba histolytica is an anaerobic parasitic amoebozoan, part of the genus Entamoeba. Predominantly infecting humans and other primates causing amoebiasis, E. histolytica is estimated to infect about 35-50 million people worldwide.
Feb 13, 2017 · This article reviews the history, epidemiology, and diagnosis of E. histolytica, a pathogenic amoeba that causes amoebiasis. It also discusses the morphological similarity and genetic diversity of E. histolytica and its nonpathogenic counterparts E. dispar and E. moshkovskii.

Dec 2, 2018 · 1. Introduction. Amoebiasis, or amoebic dysentery, is a term used to describe an infection caused by the protozoan Entamoeba histolytica [ 1 ]. Most infections are asymptomatic, but invasive intestinal disease may occur manifesting with several weeks of cramping, abdominal pain, watery or bloody diarrhea, and weight loss [ 1 ].
Entamoeba histolytica represents one of the leading causes of parasitic death worldwide. Although identified as the causative agent of amebiasis since 1875, the molecular mechanisms by which the parasite causes disease are still not fully understood.
