Abstract: Horizontal transfer of plasmid-mediated antibiotic resistance has rarely been documented in vivo. Utilizing long-read (Oxford Nanopore) and short-read (Illumina) sequencing, we confirmed that a gut-colonizing Escherichia coli and a hypervirulent Klebsiella pneumoniae ST23, isolated from… read more here.
