Comparative multi-isolate genome analysis. (A) Read-mapping outputs from whole genome sequencing of an additional 12 ST17 and 14 ST203 isolates against the completely-assembled chromosome sequence for Aus0085. The six genomic regions and integrase gene present in all ST203 isolates and absent in all ST17 isolates are highlighted and numbered. The remaining unnumbered highlighted areas correspond to regions in the Aus0085 genome that are not present in Aus0004. (B) SNP-based neighbor-joining tree, showing the relationship between the ST17 and ST203 isolates. (C) Venn diagram depicting the shared genes present in all the ST17 and ST203 strains and the specific genes that were present in all ST17 and absent from all ST203 isolates, and vice-versa.
