      <i>Escherichia coli</i> sequence type 410 (ST410) has been reported worldwide as an extraintestinal pathogen associated with resistance to fluoroquinolones, third-generation cephalosporins, and carbapenems. In the present study, we investigated national epidemiology of ST410 <i>E. coli</i> isolates from Danish patients. Furthermore, <i>E. coli</i> ST410 was investigated in a global context to provide ...
    • Molecular and epidemiological characterization of carbapenemase-producing Enterobacteriaceae in Norway, 2007 to 2014 

      Samuelsen, Ørjan; Overballe-Petersen, Søren; Bjørnholt, Jørgen; Brisse, Sylvain; Doumith, Michel; Woodford, Neil; Hopkins, Katie L.; Aasnæs, Bettina; Haldorsen, Bjørg; Sundsfjord, Arnfinn (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-15)
      The prevalence of carbapenemase-producing Enterobacteriaceae (CPE) is increasing worldwide. Here we present associated patient data and molecular, epidemiological and phenotypic characteristics of all CPE isolates in Norway from 2007 to 2014 confirmed at the Norwegian National Advisory Unit on Detection of Antimicrobial Resistance. All confirmed CPE isolates were characterized pheno- and genotypically, ...
    • Multi-Locus variable number of tandem repeat analysis for rapid and accurate typing of virulent multidrug resistant escherichia coli clones

      One hundred E. coli isolates from Norway (n = 37), Sweden (n = 24), UK (n = 20) and Spain (n = 19), producing CTX-M-type - (n = 84), or SHV-12 (n = 4) extended spectrum β-lactamases, or the plasmid mediated AmpC, CMY-2 (n = 12), were typed using multi-locus sequence typing (MLST) and multi-locus variable number of tandem repeat analysis (MLVA). Isolates clustered into 33 Sequence Types (STs) and 14 ...
