Abstract

In this study, we isolated and molecularly characterized 10 (1.6%) C. difficile isolates from 644 commercially available raw meat samples. Molecular typing by PFGE and ribotyping revealed NAP and ribotypes commonly associated with human clinical cases, suggesting retail meat could be a possible source of transmission warranting further investigation.
