Clostridium difficile intestinal infection is a major nosocomial hazard in patients receiving antimicrobial therapy. Rationale for rapid diagnosis include lifesaving antimicrobial therapy in patients with severe colitis and early isolation measures for transmission control. We have therefore analysed the sensitivity
