What type of bacteria can cause hemorrhagic colitis?

Hemorrhagic colitis is primarily caused by infection with certain strains of Escherichia coli, particularly Shiga toxin-producing E. coli (STEC), such as E. coli O157:H7. These bacteria can lead to severe gastrointestinal symptoms, including bloody diarrhea and abdominal cramps. Infections often stem from contaminated food or water, particularly undercooked ground beef and unwashed vegetables. Prompt medical attention is essential to manage symptoms and prevent complications.
