Quick Summary

Shigella boydii is a species of rod-shaped bacteria belonging to the genus Shigella. These bacteria are gram-negative, non-spore-forming, and nonmotile. They are normal inhabitants of the human intestinal tract and are a cause of bacillary dysentery, also known as shigellosis.1

Dysentery is an infectious disease characterized by intestinal inflammation, abdominal pain, and diarrhea containing blood and mucus. Bacillary dysentery, caused by Shigella bacteria, can range from mild to severe. S. boydii, along with S. sonnei and S. flexneri, are implicated in causing dysentery. The disease is typically spread through contaminated food or water. Treatment for bacillary dysentery involves antibiotics.21
