Dysentery is an intestinal infection that is caused by various bacterial pathogens. One such pathogen is the Flexner dysentery bacillus.
The pathogen F. flexneri is a Gram-negative pathogen that has the ability to cross the intestinal barrier and colonize the intestinal wall. Once in the body, the microbe affects the mucous membrane and causes the formation of inflammatory foci. A person infected with Flexner's dysentery becomes infectious to others even before the onset of clinical manifestations
