The changing epidemiology of carbapenemase-producing<i>Klebsiella pneumoniae</i>in Italy: toward polyclonal evolution with emergence of high-risk lineages

Abstract

This WGS-based survey showed that, although CG258 remained the most common CR-KP lineage in Italy, a polyclonal population has emerged with the spread of the new high-risk lineages CG307, ST101 and ST395, while KPC remained the most common carbapenemase.
