Dysentery (formerly known as flux or the blooy flux) is an infection of the digestive system that results in severe diarrhea containing mucus and blood in the feces and is typically the result of unsanitary water containing micro-organisms which damage the intestinal lining. There are two major types of dysentery due to micro-organisms: amoebic dysentery, and bacillary dysentery mainly due to one of three bacteria. Dysentery can also be caused by certain medications; for example, some steroids can impact bowel movements.
