Clinical isolate Pseudomonas aeruginosa Mus showed resistance both to extended-
spectrum cephalosporins and to aztreonam. We detected a typical double-disk synergy …

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 …

ABSTRACT A chromosomally encoded oxacillinase, OXA-69, was characterized from
Acinetobacter baumannii AYE. β-Lactamase OXA-69 shared 97% amino acid identity with …

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 …

Genetic structures surrounding the carbapenem-hydrolyzing oxacillinase gene bla OXA-58
were characterized in a series of OXA-58-positive Acinetobacter baumannii strains isolated …

Emergence and dissemination of Enterobacteriaceae isolates harboring carbapenemases
represent a significant threat to the management of nosocomial infections (6). Carbapenem …

During 2005 we detected a multicity outbreak of infections or colonization due to high-level
imipenem-resistant Acinetobacter baumannii (MIC, 64 μg/ml). One hundred isolates from …

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 …

Pseudomonas aeruginosa AH, isolated in Ankara, Turkey, was highly resistant to
ceftazidime (MIC, 128 microg/ml) and produced a beta-lactamase that gave a doublet of …

We investigated the spread of blaOXA-51-type β-lactamase genes in 200 Acinetobacter spp.
clinical strains isolated in Argentina from 1982 to 2005. blaOXA-51-type genes were present …
