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 an infection of the intestines which causes the passage of bloody stools mixed with mucus. It is caused either by bacteria such as Shigella, or by parasites such as Entamoeba. These forms are called bacillary dysentery, or shigellosis, and amoebic dysentery respectively.
