First description of blaNDM-1, blaOXA-48, blaOXA-181 producing Enterobacteriaceae strains in Romania

We report the first isolation and characterization of several Enterobacteriaceae strains harboring blaNDM-1, blaOXA-48 and/or blaOXA-181 genes in a Romanian emergency teaching hospital. Between January 2010 and September 2012 nine carbapenemase-producing Enterobacteriaceae strains were identified. The blaNDM-1 gene was present in two Enterobacter cloacae strains, an Escherichia coli and two Klebsiella pneumoniae strains. One of these K. pneumoniae strains also harbored the blaOXA-181 gene. Three other K. pneumoniae strains and one Serratia marcescens carried blaOXA-48.
