Phylogeny of the genomic sequence data of 25 representative strains. The phylogenetic tree was generated based on multiple alignments of the whole-genome sequences using REALPHY (https://realphy.unibas.ch/realphy/). Genomes of A. baumannii strains AYE, ACICU, and ATCC 17978 were included as reference strains of International clone (IC) I, IC II, and the sporadic sequence type ST437, respectively (GenBank accession numbers: NC_010410.1, NC_010611.1, and NZ_CP018664.1, respectively). Clusters, based on comparative sequence analysis of the ampC and blaOXA-51-like loci, were indicated in text boxes. Branches, isolates and clusters belonging to ICs I and II were colored in red and blue, respectively. Branches, isolates and cluster belonging to ST158 were colored in green
