Distribution of plasmid groups carrying blaCTX-M-15, blaNDM-1, and blaOXA-48 across the phylogeny. Phylogenetic trees of each CG were obtained with BEAST (represented in Fig. S4 and S5). PGs carrying each β-lactamase gene were associated with each genome in the phylogenetic tree. In the key, black labels represent common PGs (>5 plasmids), and gray labels represent uncommon PGs (<5 plasmids).
