Clostridioides difficile infection (CDI)

What is CDI?

Clostridioides difficile (C. difficile or C. diff) is one of many types of bacteria that can cause inflammation of the colon (colitis). CDI can occur when antibiotics kill other bowel bacteria and allow C. difficile to overgrow. As C. difficile grows, it produces toxins. These toxins can damage the bowel, causing diarrhea and other intestinal problems. Sometimes, C. difficile causes more serious problems that require hospitalization and, in rare instances, can cause death.
