Clonal group heatmaps of carbapenem-resistant K. pneumoniae displaying distributions of (a) key resistance mechanisms. The aminoglycoside, quinolone, and tetracycline groups refer to acquired genes conferring resistance to the antibiotic group. (b) Virulence factors, K locus, and O locus. (c) Plasmid replicons. The values represent the proportions of isolates within each clonal group bearing the individual genetic elements displayed on the horizontal axis. Factors/elements with overall prevalence <10% are not displayed in this figure. Abbreviations: CG, clonal group; CP, carbapenemase-producing; ESBL, extended-spectrum β-lactamase; ST, sequence type.
