Preventing Dysentery. Dysentery is an inflammation of the intestines that causes severe, painful diarrhea. The bacterial form of dysentery, shigellosis, is caused by Shigella bacteria (shigellosis is the most common cause of severe diarrhea in the United States). Amebiasis, which is sometimes called amebic dysentery, is much less common and is caused by the one-celled Entamoeba histolytica parasite. Both shigellosis and amebiasis are marked by severe, sometimes bloody, diarrhea; fever; and stomach cramps.
Dysentery is mainly caused by a bacterial or protozoan (one cell organism, such as an amoeba) infection. It can also be caused by a parasitic worm infestation. More rarely, a chemical irritant or viral infection can also be a cause.
