A novel, non-conjugative plasmid pKP1034 isolated from a fosfomycin-resistant, carbapenemase-producing Klebsiella pneumonia strain KP1034 was recently reported to carry fosA3, blaKPC-2, blaCTX-M-65, blaSHV-12 and rmtB genes, and was hypothesized to evolve from several recombination events of two closely related plasmids, pHN7A8 and pKPC-LK30 [1]. In this study, a plasmid pCT-KPC334 carrying fosA3, blaKPC-2, blaCTX-M-65, blaSHV-12, blaTEM-1, and rmtB genes was identified, providing evidence on the evolutionary pathway of plasmids harboring fosA3-blaKPC-2 genes.
