Shigella flexneri

Shigella dysenteriae is a Gram-negative, non-motile bacterium causing bacillary dysentery. It’s transmitted primarily through the fecal-oral route, requiring a low dose to initiate infection. Symptoms include bloody diarrhea and abdominal cramps. Diagnosis involves stool cultures, and treatment may include antibiotics for severe cases. Prevention focuses on hygiene and clean water.
