Dysentery is a severe diarrhea illness often associated with blood in the feces. It is caused by ingestion of food containing bacteria, a disease in which inflammation of the intestines affect the body significantly.
There are two major types: shigellosis, which is caused by one of several type of Shigella bacteria; and amoebic dysentery, which is caused by the amoeba Entamoeba histolytica.
Shigellosis
A patient with shigellosis will often recover without antibiotic treatment. However, treatment by antibiotics is usually recommended because the disease is relatively severe, and it is highly contagious. It can be transmitted by "fomites", for example clothes, doorknobs, toilet seats, etc. The antibiotics norfloxacin, ampicillin and cotrimaxozole may be used.
See shigellosis for more information.
Amoebic dysentery
Amoebic dysentery is transmitted by contaminated water, and is well known as a "travellers dysentery", although it is occasionally seen in industrialized countries. Liver infection, and subsequent amoebic abscesses can occur. It can be treated with metronidazole or related azole drugs.de:Entamoeba histolytica fr:Dysenterie nl:Dysenterie pt:Disenteria sv:Dysenteri
