A nosocomial outbreak of Acinetobacter baumannii isolates expressing the carbapenem-hydrolysing oxacillinase OXA-58.
OBJECTIVE The aim of this study was to analyse the spread of the bla(OXA-58) gene as a source of carbapenem resistance in Acinetobacter baumannii in the burns unit of a university hospital in Toulouse in 2003-2004. METHODS Six carbapenem-resistant A. baumannii isolates from six patients, and a carbapenem-resistant environmental A. baumannii isolate were collected in the burns unit of the Rang...
متن کاملCarbapenem-resistant Acinetobacter baumannii isolates from Tunisia producing the OXA-58-like carbapenem-hydrolyzing oxacillinase OXA-97.
The basis of the beta-lactam resistance of 39 multidrug-resistant Acinetobacter baumannii isolates recovered from hospitalized patients was studied. These isolates were collected from 2001 to 2005 at the Sahloul Hospital in Sousse, Tunisia. They belonged to two distinct clones. One clone that grouped 19 isolates produced a carbapenem-hydrolyzing oxacillinase, OXA-97, that differed from OXA-58 b...
متن کاملFirst report of the carbapenem-hydrolyzing oxacillinase OXA-58 in Acinetobacter baumannii isolates in Italy.
Emergence of Acinetobacter baumannii with resistance or reduced susceptibility to carbapenems has been reported worldwide (4). Acinetobacter may develop resistance to carbapenems through various mechanisms, including decreased permeability, efflux pump overexpression, and production of carbapenemases (3, 4, 9). Four of the eight carbapenemase-hydrolyzing oxacillinase (OXA) clusters have been id...
متن کاملOutbreak of infection by carbapenem-resistant Acinetobacter baumannii producing the carbapenemase OXA-58 in Belgium.
Carbapenem-resistant Acinetobacter baumannii isolates were obtained from 17 patients between September 2004 and August 2005 at the Academisch Ziekenhuis Vrije Universiteit Brussel, Brussels, Belgium. These multidrug-resistant isolates, which belonged to a single clone, remained susceptible to colistin and tigecycline only and produced the carbapenem-hydrolyzing oxacillinase OXA-58. This study h...
متن کاملWide dissemination of OXA-23-producing carbapenem-resistant Acinetobacter baumannii clonal complex 22 in multiple cities of China.
OBJECTIVES In this study, multilocus sequence typing (MLST) was used to describe the genetic backgrounds of carbapenem-resistant Acinetobacter baumannii (CRAB) and carbapenem-susceptible A. baumannii (CSAB) from multiple cities of China. METHODS One hundred and fifty-two CRAB and 74 CSAB isolates obtained from 16 cities of China were selected for molecular characterization by MLST. eBURST was...
