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.
Amoebic dysentery is transmitted through contaminated food and water. Amoebae spread by forming infective cysts which can be found in stools, and spread if whoever touches them does not sanitize their hands.lthough it is commonly associated with tropical climates, the first documented case was in St Petersburg, Russia. Amoebic dysentery is often confused with  traveler's diarrhea , or  Montezuma's Revenge  in Mexico, because of the prevalence of both in developing nations.
