Entamoeba histolytica is the causative agent of amoebiasis. The majority of patients will have asymptomatic or low level disease with a gradual onset of diarrhea with generalized abdominal tenderness. Fever is not usually associated with amoebic disease. Mucus and/or blood may be present if the organism penetrates the bowel wall and causes mucosal damage. (Van Hal etal., 2007)
