Entamoeba histolytica infection

Amebiasis is a disease caused by the parasite Entamoeba histolytica. It can affect anyone, although it is more common in people who live in tropical areas with poor sanitary conditions. Diagnosis can be difficult because other parasites can look very similar to E. histolytica when seen under a microscope. Infected people do not always become sick 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 Entamoeba histolytica is a protozoan parasite that accounts for an estimated 100,000 annual deaths (71). Infection ranges from asymptomatic colonization of the large bowel to severe invasive intestinal and extra-intestinal disease

The cause of amebiasis is infection by the protozoan parasite Entamoeba histolytica. It begins when a person drinks contaminated water or eats foods contaminated with the cystic form (infective stage), comes in contact with contaminated colonic irrigation devices or the fecally contaminated hands of food handlers, or by oral-anal sexual practices When your gut (intestines) becomes infected with the parasite Entamoeba histolytica (often shortened to E. histolytica), the condition is known as amoebiasis. E. histolytica lives in the intestines of infected people. It can be passed out in their stools (faeces) Deficiencies in hygiene and sanitary practices and overcrowding are predisposing factors for infection. Entamoeba histolytica is found worldwide and remains an important health problem in developing countries in which sanitation, infrastructure, and health education are not adequate. However, E. histolytica is also seen in developed countries. Humans are infected by two morphologically identical species of Entamoeba: Entamoeba histolytica causes amebic colitis and liver abscess, and Entamoeba dispar is noninvasive. Several weeks of culture and isoenzyme (zymodeme) analysis are required to differentiate E. histolytica from E. dispar

Entamoeba histolytica is the name of the parasite responsible for amebiasis. It is a small parasite that exits infected individuals through the feces as a cyst. The parasite can remain a cyst in the soil for months before someone ingests it in contaminated food or water Amebiasis is a parasitic infection of the intestines caused by the protozoan Entamoeba histolytica, or E. histolytica. The symptoms of amebiasis include loose stool, abdominal cramping, and stomach.. Gastrointestinal amebiasis is an infection of the large intestine caused by microscopic one-celled parasites commonly known as amoebas (Entamoeba histolytica). Because these parasites live in the large intestine, they travel in the feces of infected people, and can contaminate water supplies in places where sanitation is poor Entamoeba histolytica is the responsible parasite of amoebiasis and remains one of the top three parasitic causes of mortality worldwide. With increased travel and emigration to developed countries, infection is becoming more common in nonendemic areas

Amebiasis is a disease caused by a parasite known as Entamoeba histolytica. Amebiasis is most common in people living in the tropics with poor sanitation. It can also be found in any setting where sanitation is poor. Men who have sex with men are also at increased risk for amebiasis Entamoeba histolytica and Entamoeba dispar, a recently distinguished morphologically similar but nonpathogenic species, infect 10% of the world's population [ 1 ]. E. histolytica infection has been described in travelers to regions of endemicity (portions of South America, Central America, Africa, and Asia) [ 2-5 ] 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. E. histolytica infection is estimated to kill more than 55,000 people each year Amoebiasis is caused by the parasite Entamoeba histolytica. The parasite exists in two forms: an infective cyst and a potentially pathogenic trophozoite. It should not be confused with the morphologically identical non-pathogenic E. dispar and E. moshkovskii

Entamoeba histolytica is a protozoan parasite that accounts for an estimated 100,000 annual deaths ( 71 ). Infection ranges from asymptomatic colonization of the large bowel to severe invasive intestinal and extra-intestinal disease. The parasite life cycle is relatively simple: humans orally ingest the cyst form from contaminated sources. [Cecil, p. 2043] Families with poor sanitation are at increased risk for E. histolytica infection. Transmission occurs by ingestion of water or food contaminated with feces containing cysts, which are relatively resistant to chlorine water treatment Entamoeba histolytica infection. Entamoeba histolytica is acquired in warm climates via the ingestion of cysts in fecally contaminated food or water. Infected individuals are often asymptomatic. Amebic dysentery may occur, but hepatic abscess and other remote infections are uncommon. Because cysts are shed in the stool on an intermittent basis. Introduction.
