Fig 2.

Phylogeny of IC2 with associated carbapenemases and regions of recombination. Colored strips next to the phylogeny show region and country of isolation and presence of various carbapenemases (intrinsic and acquired). Recombination blocks (red) along the chromosome coordinates (top) are highlighted. The capsule K locus (blue) is under recombination, as is the pilus/fimbrial operon (gray), whereas phage loci (pink) are not. Two isolates of ST636 at the base of the tree show larger regions of recombination, corresponding to the fact that this ST shares alleles both with ST1 (three alleles) and ST2 (four alleles).
