The OXA β-lactamases were among the earliest β-lactamases detected; however, these
molecular class D β-lactamases were originally relatively rare and always plasmid …

A clinical strain of Acinetobacter baumannii (strain Ab41) that was resistant to all beta-lactam
antibiotics tested except ceftazidime, ceftriaxone, ceftizoxime, and imipenem produced three …

Sixty diverse clinical Acinetobacter baumannii isolates of worldwide origin were assigned to
sequence groups, based on a multiplex PCR for the ompA, csuE and bla OXA-51-like …

Objectives: Acinetobacter baumannii is a significant pathogen in health care settings. In
recent years, an increase in carbapenem resistance among A. baumannii due to Ambler …

Carbapenem resistance in Acinetobacter spp. is increasingly being associated with OXA-
type β-lactamases with weak hydrolytic activity against imipenem and meropenem. Such …

The emergence of carbapenem resistance in Acinetobacter baumannii has become a global
concern since these β-lactams are often the only effective treatment left against many …

ABSTRACT A carbapenem-resistant Acinetobacter baumannii strain was isolated in
Toulouse, France, in 2003. Cloning and expression in Escherichia coli identified the …

We investigated the mechanism of carbapenem resistance in 10 Acinetobacter baumannii
strains isolated from the United States and Mexico between 2005 and 2009. The detection of …

ABSTRACT Acinetobacter baumannii RYC 52763/97, a clinical isolate involved in a
prolonged nosocomial outbreak at our hospital, was resistant to all β-lactams tested …

Resistance to carbapenems in Acinetobacter baumannii is increasingly reported and is
mostly associated with expression of carbapenemases (3, 6). Those carbapenemases are …
