Comparison of PCR riboytpe and MLVA groups for 142 C. difficile isolates. Dendrogram is based on UPGMA analysis of capillary electrophoresis-based PCR ribotyping, and the vertical line is the cutoff point for identifying PCR-ribotype groups. Corresponding PCR-ribotype groups, MLVA34 groups, MLVA10 groups, and number of isolates are shown. MLVA groups are identified by minimum-spanning tree: one group is defined by MLVA type with less than two loci difference.
