Maximum Likelihood phylogenetic relationship of the 59 Australian Type S isolates sequenced in this study including nine international Type S sequences sourced from NCBI. The tree is based on core SNP’s identified through mapping to MAP Telford strain and rooted at the mid-point. Branches show boot strap support. Host (H) and geographical origin (O) of each isolate is displayed in colour as depicted in the legend. Isolates with names highlighted in red typed as Type S using IS1311 PCR and REA but have since been identified as Type C and two isolates with names highlighted in green are Type C strains included for comparative purposes
