KPC-3-Producing Klebsiella pneumoniae in Portugal Linked to Previously Circulating Non-CG258 Lineages and Uncommon Genetic Platforms (Tn4401d-IncFIA and Tn4401d-IncN)

Abstrakt
This study highlights a polyclonal structure of KPC-3-producing K. pneumoniae and the predominance of the ST147 clone among non-hospitalized patients in Portugal, linked to platforms still unnoticed in Europe (bla(KPC-3)-Tn4401d-IncFIA) or firstly reported (bla(KPC-3)-Tn4401d-InoN). This scenario underlines the recent penetration of successful mobile genetic elements in previously circulating MDR K. pneumoniae lineages (mainly ST147 and ST15) in Portugal, rather than the importation of the global lineages from clonal group 258.
