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] .

Antigen consists of a crude soluble extract of axenically cultured organisms. The EIA test detects antibody specific for E. histolytica in approximately 95% of patients with extraintestinal amebiasis, 70% of patients with active intestinal infection, and 10% of asymptomatic persons who are passing cysts of E. histolytica. If antibodies are not ...

2023年4月17日 · Entamoeba histolytica is a protozoan that causes intestinal amebiasis as well as extra-intestinal manifestations. Although 90 percent of E. histolytica infections are asymptomatic, nearly 50 million people become symptomatic, with about 100,000 deaths yearly.

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.

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).

Amebiasis is a gastrointestinal disorder caused by a single-celled parasite called Entamoeba histolytica (E. histolytica), which is spread through human feces. People can get infected with this parasite by consuming contaminated food or beverages .

2024年5月2日 · Amebiasis is caused by the parasite Entamoeba histolytica, or E. histolytica. Anyone can get amebiasis. It is more common if you live in a tropical area with poor sanitary conditions or travel to one of these areas. If you think you have amebiasis, see your healthcare provider. The disease can be difficult to diagnose.

2024年12月21日 · Entamoeba histolytica is a protozoan parasite responsible for amoebic dysentery and amoebiasis. It primarily infects the intestinal tract, causing symptoms like diarrhea, abdominal pain, and sometimes liver abscesses. The parasite has two forms: the infectious cyst and the trophozoite, which causes tissue damage.

Entamoeba histolytica is a nationally and provincially notifiable disease; E. dispar is a harmless commensal with no public health implications. Colonization of the stool with E. dispar suggests potential exposure to other pathogens with fecal–oral transmission but does not cause diarrhea.

Entamoeba histolytica is an ameba that feeds on cells in the human colon. It is the cause of amebic dysentery (bloody diarrhea) as well as colonic ulcerations. The infection is also referred to as amebiasis. If the organisms spread throughout the body via the bloodstream they may cause abscesses in the liver or, less frequently, other organs.
