PP23-KPC, and numbers of p1011-KPC2, p14057A, YLH6_P3, pP23-KPC, and pR31-KPC are MH734334, KY296095, MK882885, CP065418, and CP061851, respectively. and CP061851, respectively. In YLH6_P3 and pP23-KPC, six copies of IS26 (4 intact and two truncated) and2.5. The Accessory Regions of pR31-KPC truncated) have been found inside the blaKPC-2 region, refour copies of IS26 (three intact and 1 two.5. The Accessory Regions ofof pR31-KPC comprise two IS26-based regions, the IS26-blaKPCspectively, formingregions structures, with adjacent IS26 regions overlapping every single other.

Tn6296 was initially identified in MDR plasmid pKP048 from Klebsiella pneumoniae. In addition, it was generated in the insertion on the core blaKPC-2 genetic platform (Tn6376 laKPC-2 SKpn6 orC rf6 lcA epB) into Tn1722, resulting in truncation of mcp (Figure 2a). In pR31-KPC, the aforementioned core blaKPC-2 genetic platform is intact, but has been split into two parts, every of that is bordered by two IS26 components (either in the exact same or opposite directions), producing the IS26-blaKPC-2-IS26 unit and IS26-Tn6376-IS26 area, which have the potential to move (Figure 2a). Each in the regions lack the common 5 bp target web-site duplications, suggesting that the acquisition of these entities may perhaps have occurred by means of the IS26-mediated homologous recombination. In p1011-KPC2, two copies of IS26 had been discovered in the boundaries on the core blaKPC-2 genetic platform in opposite directions, translocating the core platform and truncating tnpATn6376 into a 2455 bp fragment.
