Concordance between clustering of MLST and whole-genome CGH profiles for the 45 C. jejuni isolates included in this study. Bootstrap support is shown for the statistically robust clusters (shown in red on the dendogram; CGH profiles boxed in blue). Log Ratio data has been colour-coded according to data interpretation thresholds described in Taboada et al. . Strains showing discordant clustering results are boxed in green.
