Bacterial dysentery is an acute intestinal infection primarily caused by Shigella bacteria, leading to severe inflammation of the colon. It causes frequent, often bloody diarrhea with mucus, abdominal cramps, and fever. This highly contagious disease is most common in areas with poor sanitation, particularly affecting young children and immunocompromised individuals.
