A plasmid-borne blaOXA-58 gene confers imipenem resistance to Acinetobacter baumannii isolates from a Lebanese hospital.
We investigated the basis of the carbapenem resistance of 17 multidrug-resistant Acinetobacter baumannii clinical isolates collected from 2004 to 2005 at the Saint George University Hospital in Beirut, Lebanon. A. baumannii isolates were clonally related and were susceptible to colistin and trimethoprim-sulfamethoxazole, susceptible or intermediate to ampicillin-sulbactam and meropenem, and res...
متن کاملPolyclonal spread of bla(OXA-23) and bla(OXA-58) in Acinetobacter baumannii isolates from Argentina.
BACKGROUND In order to study the enzymatic carbapenem resistance mechanisms in Acinetobacter baumannii isolates from Argentina, we performed molecular characterization on 41 epidemiologically unrelated strains isolated from 1995 to 2006 with diminished susceptibilities to imipenem and meropenem. METHODOLOGY Acinetobacter baumannii isolates were identified with the ARDRA technique. The total g...
متن کاملDiversity of carbapenem resistance mechanisms in Acinetobacter baumannii from a Taiwan hospital: spread of plasmid-borne OXA-72 carbapenemase.
OBJECTIVES We investigated the molecular epidemiology of carbapenem-resistant Acinetobacter baumannii from a Taiwanese hospital and determined the mechanisms responsible for resistance. METHODS Ninety-two consecutive meropenem-resistant A. baumannii isolates collected between January 2005 and June 2007 were screened for genes encoding OXA carbapenemases, metallo-beta-lactamases and for the ca...
متن کاملMolecular Epidemiology of Imipenem-Resistant Acinetobacter haemolyticus and Acinetobacter baumannii Isolates Carrying Plasmid-Mediated OXA-40 from a Portuguese Hospital Major outbreaks of multidrug-resistant Acinetobacter bau-
Major outbreaks of multidrug-resistant Acinetobacter baumannii associated with nosocomial infections have been increasingly reported worldwide (1, 10, 12). The endemicity of an OXA-24/40-producing A. baumannii clone associated with mortality events in Portugal has been observed at numerous hospitals within the Iberian Peninsula (5, 6, 10). Inversely, Acinetobacter haemolyticus, isolated only oc...
