GES extended spectrum beta-lactamases in Acinetobacter baumannii in Belgium.

During a PCR-based surveillance study of beta-lactam resistance, 125 multidrug-resistant (MDR) Acinetobacter baumannii isolates were obtained from 18 hospitals in Belgium from January 2008 to December 2009. Nine GES-positive A. baumannii isolates were detected at 6 Belgian hospitals. DNA sequencing of the blaGES genes identified GES-11, GES-12 and a novel variant GES-14 which differs from GES-11 by a single amino acid substitution (Gly170Ser). All index isolates were travel-associated and originated from patients transferred from Turkey (n=2), Egypt (n=2) and Palestinian territories (Gaza) (n=... Mehr ...
