title: C. difficile PCR-ribotype 023 might go undetected when using ChromId C. difficile agar.
abstract: We compared the performance of the new chromogenic medium ChromID C. difficile with that of CLO agar. ChromID C. difficile agar is a sensitive medium that can accelerate the presumptive identification of C. difficile, however ribotype 023 might go undetected when using this chromogenic medium.
