How does Shigella cause dysentery?
Shigella is relatively resistant to acid in the stomach, and few organisms are required to cause the disease. Once ingested, it multiplies in the small intestine then enters the colon, where it produces shigella enterotoxins and serotype toxin 1, which cause watery or bloody diarrhea.
What bacteria causes shigella dysenteriae?
Shigellosis is an infectious disease, caused by the Shigella bacteria, that produces stomach pain, diarrhea and fever. Shigellosis is caused by coming into contact with stool or food that is infected with the bacteria. Treatment includes rest, fluids, and in severe cases, antibiotics to treat the infection.

What kind of bacteria causes diarrhea and dysentery?
Shigella dysenteriae type 1, a gram-negative bacillus, was identified by the Japanese microbiologist Kiyoshi Shiga as a cause of the dysentery syndrome in 1897. 1 Subsequently, three other species of Shigella causing endemic dysentery or diarrhea were identified and received eponymous species names ( S. flexneri]
What does Shigella do to the human body?
After entering the body in contaminated food, Shigella group bacteria infect cells that line the inside of the intestines and often produce a toxin. The toxin affects both the intestines and the nervous system. Cells of the intestinal lining are damaged, which causes inflammation and bleeding.
What are the symptoms associated with Shigella?
