pecorum data (Table 1), while the 16S rRNA, 16S/23S intergenic spacer, omcB, pmpD, tarP, and MACPF

genes were compared with the E58 reference strain as no other data is currently available for these genes.

In total, 16244 bp of data was analysed which represents 1.62% of the complete C. pecorum genome. The two housekeeping and non-coding genes, 16S rRNA and 16S/23S intergenic Mannose-binding protein-associated serine protease spacer, were sampled to provide a counterpoint to the coding sequence data and represent genes under stabilising selection. Across a total of 3548 bp of data from these two genes, only two SNPs were observed (0.13%). Analysis of ompA revealed a significantly higher level of polymorphisms (122), which equated to 10.43% of the 1170 bp gene and a mean diversity of 0.162. Both incA and ORF663, while possessing fewer individual polymorphisms than ompA (116 and 66 respectively), exhibited a higher percentage of nucleotide diversity at 11.79% and 11.96% respectively.
