Polymorphic sites detected at the nine loci examined in this study. All polymorphic sites are shown relative to the ST1 sequence. Polymorphic sites are shown, while dots indicate nucleotides identical to ST1. The number of strains possessing each ST is shown at the end of each sequence string while the status of each site as a potential synonymous or non-synonymous change is shown by S or N respectively. The numbers above the gene designations represent the base number in the 4,396 bp concatenated sequence.
