Clostridium difficile is the major cause of nosocomial diarrhea and pseudomembranous colitis. C. difficile infection usually occurs when the normal microflora of the intestinal tract is altered or killed by antibiotics. Once C. difficile growth begins, toxins A and B are produced, causing diarrhea and colitis.
The disease can be treated with metronidazole or vancomycin, but relapses occur in about 20% of patients who develop the infection.
