Fig 1.

Intra- and interassay variability of the PCR-ribotyping/DiversiLab C. difficile typing platform. Dendrogram illustrating the gel electrophoresis profiles of 24 PCR-ribotyping reactions obtained for eight different C. difficile isolates (isolates A to H). Samples loaded onto the first Agilent chip are indicated by lightface capitalized letters, while PCR-ribotyping reactions loaded onto the second Agilent chip are indicated by letters in bold italics. The percent SI is indicated by the bar below the dendrogram; isolates with a SI of ≥95% are considered very related or identical.
