Amoebiasis is a infectious disease caused by the parasite Entamoeba histolytica. It is a parasitic infection of the large intestine and characterized by non specific diarrhea with loose, semi formed, foul smelling stools, or dysentery with mucous, traces of blood and small quantities of stools passed repeatedly. Often there is an ineffectual urge to defecate again and again, with very little stool actually being passed. There is much flatulence with abdominal cramps. In severe cases, the liver and other organs may get affected, causing specific conditions related to organ, e.g., hepatitis, cysts, abscess, etc. The most common symptoms of amoebiasis are diarrhea (which may contain blood), stomach cramps and fever.
