Characterization of Extensively Drug-Resistant or Pandrug-Resistant Sequence Type 147 and 101 OXA-48-Producing Klebsiella pneumoniae Causing Bloodstream Infections in Patients in an Intensive Care Unit.

ABSTRACT: Carbapenem-resistant Klebsiella pneumoniae causes important health care-associated infections worldwide. An outbreak of sequence type 11 (ST11) OXA-48-producing K. pneumoniae (OXA-48-Kp) isolates occurred in Tzaneio Hospital in 2012 and was contained until 2014, when OXA-48-Kp reemerged. The present study involved 19 bloodstream infection (BSI) OXA-48-Kp isolates recovered from 19 intensive care unit (ICU) patients hospitalized between August 2014 and July 2016. MICs were determined by broth microdilution. Beta-lactamase genes were detected by PCR. All isolates were typed by pulsed-field gel electrophoresis/multilocus sequence typing (PFGE/MLST), and 10 representative isolates were typed by next-generation sequencing (NGS). Of the 19 study patients, 9 had previous hospitaliza
