Figure 4 The genetic structure features of pNDM-EcHK001-like plasmids. The blaNDM-1 and blaSHV-12 gene are indicated in red and yellow. The blaNDM variants and the blaSHV-11 gene are indicated in purple and dark orange. The insertion sequences ΔISAba125, IS5 and IS26 are indicated in black. Other genes in ΔTn125 and blaSHV-12-carrying transposon are indicated in light gray and dark gray, respectively.
