Evaluation of the performance of the PCR-ribotyping/DiversiLab C. difficile typing platform at the local level. The dendrogram illustrates the electrophoresis profiles of a collection of 74 C. difficile isolates obtained from both the CDC and our institution. Isolates obtained from the CDC are indicated by their PFGE pulsotype and are in bold italics, while patient isolates are indicated numerically. The collection was differentiated into 17 clusters with 15 unrelated strains, yielding a discrimination index of 0.954. The percent SI is indicated by the bar below the dendrogram; ≥95% are very related or identical.
