Carbapenem-Resistant Isolates of Klebsiella pneumoniae in China and Detection of a Conjugative Plasmid (blaKPC-2 plus qnrB4) and a blaIMP-4 Gene

Wei et al. ([13][1]) recently described the emergence of plasmid-mediated KPC-2 carbapenemase in a Klebsiella pneumoniae isolate from China. Interestingly, KPC-producing isolates, which were initially restricted to hospitals located in the New York City area ([2][2]), have recently been detected in
