Amoebiasis causes

Overview
Entamoeba histolytica can live in the large intestine (colon) without causing disease. However, sometimes, it invades the colon wall, causing colitis,  acute dysentery, or long-term (chronic) diarrhea. The infection can also spread through the blood to the liver and, rarely, to the lungs,  brain or other organs. This condition can be seen anywhere in the world, but it is most common in tropical areas with crowded living conditions and poor  sanitation. Africa, Mexico, parts of South America, and India have significant health problems associated with this disease. Entamoeba histolytica is spread through food or water contaminated with stools. This is common when human waste is used as fertilizer. It can also be spread from person to person -- particularly by contact with the mouth or rectal area of an infected person.
