Antimicrobial resistance gene and class distribution among 323 isolates. a Gene presence-absence matrix showing the distribution of antimicrobial resistance genes and SCCmec types across the phylogeny (tree is identical to that in Fig. 1c). Red blocks indicate presence of gene listed to the right of the panel. SCCmec types are color-coded as green = Type II, aqua = Type IV, blue = Type V. b Histogram showing distribution of the number of antimicrobial classes each genome is resistant to. c Bar chart showing the number of genomes resistant to each individual antimicrobial class.
