The worldwide spread of Klebsiella pneumoniae carbapenemase-producing Klebsiella pneumoniae (KPC-Kp) isolates was reported to be caused by dissemination of 1 clonal complex (i.e., clonal group [CG] 258, which includes sequence types [STs] 258 and 512). We conducted whole-genome sequencing and epidemiologic analysis of all KPC-Kp isolates in France in 2018 and found that new successful high-risk clones of ST147, ST307, ST231, and ST383 are now the main drivers of bla(KPC) genes. The bla(KPC) genes were mostly carried by Tn4401a and Tn4401d structures and a new non-Tn4401 element. Our epidemiologic investigations showed that the emergence of these non-CG258 KPC-Kp isolates in France was linked to dissemination of these clones from Portugal. Thus, KPC-Kp epidemiology has changed in Europe, at least in several non-KPC-endemic countries of western Europe, such as France and Portugal, where CG258 is not the most prevalent clone.
