C. difficile
Clostridium difficile is a motile bacterium that can be part of the natural
intestinal flora. Infection can occur through the use of broad-spectrum
antibiotics which lower the relative amount of other normal gut flora. When this situation occurs, C. difficile proliferates and infects the large intestine. The bacterium then releases two enterotoxins that destroy the intestinal lining and cause diarrhea.
