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.
There are two major classifications of dysentery: bacillary and amebic, caused respectively by bacteria and by amoebas. Bacillary dysentery, or shigellosis, is caused by bacilli of the genus Shigella. Symptomatically, the disease ranges from a mild attack to a severe course that commences suddenly and ends in death caused by dehydration and poisoning by bacterial toxins.
