Entamoeba histolytica is a pathogenic ameba that causes intestinal and extraintestinal infections. Trophozoites are the infective form of the parasite that multiply by binary fission and produce cysts. Trophozoites are passed in feces and can invade the intestinal mucosa or blood vessels. Symptoms include dysentery, liver abscesses, and peritonitis.
Apr 17, 2023 · 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.[2]
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]

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.
Dec 2, 2018 · Entamoeba histolytica is an invasive enteric protozoan [1, 2, 10]. Infection typically begins with the ingestion of mature, quadrinucleated cysts found in fecally contaminated food or water. Excystation occurs in the small intestine with the release of motile trophozoites, which migrate to the large intestine.
Nov 12, 2020 · histolytica. Entamoeba histolytica is an extracellular enteric eukaryotic parasite. Globally, an average of 50 million cases and 55,000 to 100,000 deaths are due to E. histolytica infection each year, primarily impacting the developing world [ 1, 2 ]. The world is widely unprepared for an outbreak of E. histolytica due to the lack of a vaccine ...
