Differentiating between these two pathogens and accurately identifying the four species of Shigella are therefore challenging. For older children, a high protein with low residue supplemented by vitamins is indicated. On EMB agar plate, colonies are smooth, convex, colorless, smooth and round; do not ferment lactose but do ferment sucrose with acid and no gas productionLipopolysaccharide as endotoxin contribute to the irritation of the bowel wallHeat-labile endotoxin affects both the gut and the central nervous system to paralyze the hostAn acute bacterial disease of the intestine characterized by diarrhea, accompanied by fever and vomiting, cramps and tenesmus.In severe cases, the stools may contain blood, mucus and pus after a short incubation period of 1-3 days.

Shigella are microbiologically characterized as gram-negative, non-spore-forming, nonmotile bacteria.
This disease also is caused by an amoeba. Shigella, genus of rod-shaped bacteria in the family Enterobacteriaceae, species of which are normal inhabitants of the human intestinal tract and can cause dysentery, or shigellosis. The common name for Shigella is Dysentery.
belongs to the family Enterobacteriacae.It is a small, unencapsulated, non-motile gram-negative rod.
Rehydration is accomplished by intravenous injections, administered preferably in a hospital.Overcoming the infection by use of drugs. There are four species of Shigella, classified on the basis of biochemical and serological differences: S. dysenteriae, S. flexneri, S. boydii, and S. sonnei ().
Shigella sonnei (the most common species in the United States) Shigella flexneri; Shigella boydii ; Shigella dysenteriae; S. dysenteriae and S. boydii are rare in the United States, though they continue to be important causes of disease in the developing world.

The bacteria are able to survive contaminated environments as well as the acidity of the human gastro-intestinal tract.
A person loses so much water it is fatal. This causes a severe, watery diarrhea.
The causative agent of human shigellosis, Shigella causes disease in primates, but not in other mammals. Shigella dysenteriae are Gram-negative, rod (bacillus) shaped, non-motile, non-spore-forming, facultative anaerobic bacteria that are not capsualted. The problem of nutrition is serious in the case of an infant.
Drugs are available to combat this disease and minimize its complications.The provision of adequate nourishment. Shigella bacteria are mainly found in humans, so person-to-person spread is most common. Shigella is a genus of bacteria that is Gram-negative, facultative anaerobic, non-spore-forming, nonmotile, rod-shaped and genetically closely related to E. coli.The genus is named after Kiyoshi Shiga, who first discovered it in 1897..
