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. Amebic infections are more prevalent in countries with lower socioeconomic conditions.
Epidemiology. Amebiasis is distributed worldwide, particularly in the tropics, most commonly in areas of poor sanitation. E. histolytica is a common diarrheal pathogen in returned travelers. Long-term travelers (duration >6 months) are much more likely than short-term travelers (duration <1 month) to develop E. histolytica infection.

In some cases, it invades the colon wall, causing colitis, acute dysentery, or long-term (chronic) diarrhea. The infection can also spread through the bloodstream to the liver. In rare cases, it can spread to the lungs, brain, or other organs.
Amoebiasis is a disease caused by Entamoeba histolytica, a protozoa which is found worldwide. Humans are the natural reservoir of E. histolytica, and infection occurs via faecal-oral transmission (e.g. contaminated hands, water, or food, and oral- anal sex ). The main symptom of infection is diarrhoea. There is a higher incidence of amoebiasis ...

Infections range from asymptomatic colonization to amebic colitis and life-threatening abscesses. Importantly, disease may occur months to years after exposure. Although E ...
