Tree for 108 genomes based on a 2.93-Mbp alignment, rooted at the midpoint of the outgroup (Ecl/Yre) branch. Nodes with <30% bootstrap support were combined forming the multifurcated dashed line; otherwise support values are shown only when <100%. Brackets: Kpn multilocus sequence type (ST). Inset: enlargement of the “core Kpn” phylogeny. Kpn2146 falls in a clade containing fellow ST11 strains Kpn JM45 and Kpn HS11286 and a tight clade (circled) of ST258 and ST512 strains. The ST258/ST512 clade is heavily sequenced, and represented here with only five of its most diverse members. Bold: complete genomes used for phyloblocks analysis. Species name abbreviations: Kpn, K. pneumoniae; Ksp, K. sp.; Kpl, K. cf. planticola; Kox, K. oxytoca; Kva, K. variicola; Eae, Enterobacter aerogenes; Ecl, E. cloacae; Ror, Raoultella ornithinolytica; Yre, Yokanella regensburgei.
