dysentery

n. intestinal disease

Dysentery (formerly known as flux or the bloody flux) is frequent, small-volume, severe diarrhea that shows blood in the feces along with intestinal cramping and tenesmus (painful straining to pass stool). Symptoms frequently associated with dysentery include fever and malaise.Dysentery has many causes, including cancer, but is typically associated with infection caused by the ingestion of food or water containing micro-organisms which cause significant inflammation of the intestinal lining. There are two major types: shigellosis, which is caused by one of several types of Shigella bacteria; and amoebic dysentery, caused by the amoeba Entamoeba histolytica. Kiyoshi Shiga discovered the dysentery bacteria in 1898. Dysentery can also be caused by certain medications, for example, some steroids can impact bowel movements.
