Shigellosis or “Bacillary Dysentery” is the infection associated with the Shigella species. Describe Shigellosis and give at least 5 known symptoms of it.
Shigellosis is an acute bacterial infection of the lining of the small and large intestine, producing diarrhea (as many as 20 bowel movements a day) with blood, mucus, and pus. Symptoms: diarrhea, nausea, vomiting, cramps, and fever. Sometimes toxemia.

The cells are highly motile and swarm across the surface of the agar plates, forming a very thin film of bacteria. When the cells stop and undergo a cycle of growth and division, the swarming periods are interspersed with periods and the colony has a distinct zonation.
