Major structural features of plasmids pKpQIL-IT (JN233705), pKPN-IT (JN233704), IncX-SHV (JN247852), and ColEST258 (JN247853). Plasmids sequenced in this study were compared with plasmids pKpQIL (NC_014016), pKPN3 (CP000648), pX1.0 (HM114226), and 15S (FJ223606), respectively. White boxes indicate plasmid scaffold regions. The genes associated with the Tra locus are indicated as capital letters within the respective boxes. Resistance genes are indicated by orange boxes, except for the blaKPC and blaSHV-11 genes, which are indicated by dark blue boxes. Transposon-related genes (tnpA, tnpR, and tnpM), insertion sequences, and the class1 integrase genes are indicated by light blue boxes. The two putative virulence clusters acquired by the pKPN-IT plasmid with respect to pKPN3 are indicated by red boxes.
