Circular representation of the IncFIB/IncFII and ColRNAI plasmids in the KPC-producing Klebsiella pneumoniae included in this study. From outside to inside: KPC-Kp_TO5 strains, KPC-Kp_TO3, and KPC-Kp_TO1. The CDS are color-coded with the direction of transcription indicated by arrowheads. The Tn4401 transposons are displayed in blue, KPC-3 in red, KPC-66 in orange, ColRNAI backbone in yellow, and other CDS in gray. Boxes indicate direct repeats (DRs).
