NCTC Clostridium difficile strains

Since many laboratories have become interested in PCR-ribotyping for Clostridium difficile, we are pleased to list below the PCR-ribotypes and toxin status for all the NCTC C. difficile strains.

These have been kindly tested for us by the Anaerobe Reference Unit in Cardiff.
