Fig. 1. Clinical symptoms of infection with Shigella spp.
Shigellosis is a self-limiting infection resulting in colonic epithelial lesions found in most patients, which is a consequence of innate and adaptive immune responses to infection. A hallmark of dysentery is small volume, bloody, mucoidal stools with a high number of neutrophils. Infection can also cause watery diarrhea, dehydration and contribute to malnutrition in endemic populations
