To our knowledge, this is the first characterization of an IncFII(pBK30683)/IncR plasmid carrying blaKPC-2 in a clinical C. freundii ST91 isolate. The findings highlight plasmid lineages as drivers of carbapenem resistance dissemination and underscore the need for plasmid-focused genomic surveillance, particularly for monitoring transferable resistance vehicles across clinically relevant hosts.
