Fig. 1. Maximum likelihood core genome phylogenetic tree of the 232 B1 phylogroup CC87 (Institut Pasteur scheme numbering) strains.

Fig. 1

The five CC87 subgroups (STWU58-STIP186, STWU58-STIP87-A, STWU155-STIP21, STWU58-STIP87-B, STWU58-STIP24) based on the Warwick University and Institut Pasteur MLST schemes are highlighted in color. The presence of the high pathogenicity island (HPI) is highlighted by red stars and ColV plasmid (defined as proposed by Reid et al.19) by green triangles. In the outermost circle, colored squares represent the number of mice killed over ten in the mouse model of sepsis11. The 26 ST58 genomes obtained from the study by Reid et al. are in bold. The tree is rooted on IAI1 (non-CC87, phylogroup B1). For the sake of readability, branch lengths are ignored and local support values higher than 0.7 are shown.
