dysentery dys·en·ter·y (dĭs'ən-těr'ē)
n.
An inflammatory disorder of the lower intestinal tract, usually caused by a bacterial, parasitic, or protozoan infection and resulting in pain, fever, and severe diarrhea, often accompanied by the passage of blood and mucus.
A painful disease of the intestines characterized by inflammation and diarrhea. Dysentery may be caused by bacteria or viruses, or may occur as the result of infestation by an amoeba.
Note: Dysentery can be transmitted by contact with water or food that has been contaminated by human waste. Public health and sanitation procedures in developed countries, however, have largely eliminated this means of transmission.
