Fig. 2

The sequence polymorphisms in the PaLoc and CdtLoc regions of the three ST11 Clostridium difficile isolates. CD630 was used as a reference. a Schematic representation of the PaLoc region and the polymorphisms within this area. b Schematic representation of the CdtLoc region and the polymorphisms within this area. The gray areas in the schematic representiations of the PaLoc and CdtLoc regions refers to coding genes, while the black areas refer to intergenic regions. Deletions are shown in orange, and insertions are shown in red. For example, D779 indicates a 779-bp deletion, and I130 indicates a 130-bp insertion. The numbers under each area indicate the number of synonymous mutations followed by the number of non-synonymous mutations. In addition, their proportions are shown in the brackets
