FIG 1.

Core genome phylogeny of 115 CRAb isolates from four medical centers in the United States. The first isolate sampled from each patient was included, and the midpoint rooted phylogeny was constructed from SNPs detected in the core genomes of all isolates (2.6-Mb core genome length), using RAxML. The phylogeny is annotated based on Oxford ST and study center of isolation. Branches are shaded by lineages and sublineages described in the text. Nodes supported by bootstrap values of 100 are marked with red dots. NF, not found; R, resistant; I, intermediate.
