Outbreak of multiple clones of imipenem-resistant Acinetobacter baumannii isolates expressing OXA-58 carbapenemase in an intensive care unit
(2006)
Objectives: To investigate the resistance mechanisms and the genetic relationship of imipenem-resistant Acinetobacter baumannii isolates recovered in the intensive care unit (ICU) of a tertiary care hospital. Methods: ...
Characterization of clinical isolates of Pseudomonas aeruginosa heterogeneously resistant to carbapenems
(2007)
Fourteen apparently carbapenem-susceptible Pseudomonas aeruginosa clinical isolates that exhibited colonies within the inhibition zone around carbapenem discs were analysed. MICs of carbapenems were determined and the ...
VIM-1 metallo-β-lactamase in Acinetobacter baumannii
(2006)
In 2004 and 2005, 5 metallo-β-lactamase (MBL)-positive Acinetobacter baumannii isolates were found in 2 Greek hospitals. Isolates were unrelated and carried blaVIM-1 in a class 1 integron; blaOXA-51- and blaOXA-58-like ...
VIM-12, a novel plasmid-mediated metallo-β-lactamase from Klebsiella pneumoniae that resembles a VIM-1/VIM-2 hybrid
(2005)
A transferable plasmid from Klebsiella pneumoniae carried a class 1 integron containing blaVIM-12, a novel blaVIM-type gene, flanked by two copies of aacA7. blaVIM-12 was clustered between bla-VIM-1 and bla-VIM-2 and ...
Outbreaks in distinct regions due to a single Klebsiella pneumoniae clone carrying a bla(VIM-1) metallo-beta-lactamase gene
(2005)
From December 2004 to March 2005, 27 Klebsiella pneumoniae clinical isolates that were positive by the imipenem-EDTA double-disk synergy test and that exhibited a single macrorestriction pattern were recovered in two ...
Detection of a novel variant bla(CTX-M-3) extended spectrum beta-lactamase gene in a community-acquired Escherichia coli isolate
(2006)
A highly cefotaxime- and cefepime-resistant but ceftazidime-sensitive Escherichia coli isolate was recovered from a community-acquired urinary infection of a Greek patient. Susceptibility testing, transfer assays, plasmid ...
VIM-1 metallo-beta-lactamase in Acinetobacter baumannii
