Towards endemicity: large-scale expansion of the NDM-1-producing Klebsiella pneumoniae ST11 lineage in Poland, 2015–16

Abstract

The K. pneumoniae ST11 NDM-1 outbreak has dramatically expanded in Poland since 2012, which may bring about a countrywide endemic situation in the near future. In addition, the so-far limited K. pneumoniae ST147 NDM-1 outbreak plus multiple NDM imports from different countries were observed in 2015-16.
