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 …

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 …

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

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 …

Three enterobacterial isolates (two Klebsiella pneumoniae and one Escherichia coli) were
recovered from three patients transferred from India to France in 2011. All three isolates …

Carbapenem resistance associated with class D β-lactamases is an increasing problem in
Acinetobacter baumannii. Most enzymes of this class reported so far belong to two …

Objectives Carbapenem-hydrolysing class D β-lactamases of the OXA-48 type are
increasingly reported from Enterobacteriaceae. β-Lactamase OXA-48 hydrolyses penicillins …

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

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

Two extended-spectrum mutants of the class D β-lactamase OXA-10 (PSE-2) from
Pseudomonas aeruginosa isolates obtained in Ankara, Turkey, were described previously …
