Amebic Dysentery

Amebiasis is an infection of the colon caused by a parasitic protozoan, the ameba Entamoeba histolytica. Several species of ameba inhabit the large intestine. Most are harmless commensals or minor parasites, usually causing little or no clinical damage. The closely related species Entamoeba coli and Entamoeba hartmanni are commensals, and infection with E. histolytica is also often asymptomatic. E. histolytica is probably a species complex, with a number of morphologically similar forms with varying degrees of invasiveness. E. hartmanni, formerly believed to be a "small race" of E. histolytica, is now recognized as a separate nonpathogenic species. Pathogenic amebas cause light to severe intestinal damage (amebic dysentery) and sometimes spread to the liver, lungs, brain, and other organs.
