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 …

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 …

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

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 …

ABSTRACT A clinical strain of Acinetobacter baumannii (strain Ab RYC 52763/97) that was
isolated during an outbreak in our hospital and that was resistant to all β-lactam antibiotics …

Clinical isolate Acinetobacter baumannii CLA-1 was resistant to a series of antibiotic
molecules, including carbapenems. Cloning and expression of the β-lactamase gene …

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 …

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

Two clonally related Acinetobacter baumannii isolates, A1 and A2, were obtained from the
same patient. Isolate A2, selected after an imipenem-containing treatment, showed reduced …

ABSTRACT A carbapenem-resistant Acinetobacter baumannii strain was isolated in Brazil in
2004 in which no known carbapenemase gene was detected by PCR. Cloning experiments …
