Genomic epidemiology reveals niche specialization and a virulence-resistance trade-off in ST23 and ST11 hypervirulent Klebsiella pneumoniae.
ST23 retains a classic hypervirulent phenotype, whereas ST11 represents a hospital-adapted convergent clone characterized by a complex resistome, an incomplete canonical virulence repertoire, and separate plasmid systems, suggesting that convergence in ST11 involves coexisting distinct plasmid systems rather than detec...
