Hidden VIM-1 metallo-beta-lactamase phenotypes among Acinetobacter baumannii clinical isolates
(2008)
A total of 87 Acinetobacter baumannii nonrepetitive consecutive clinical isolates were tested for the presence of metallo-beta-lactamases (MBLs). Results of phenotypic assays (MBL Etest, imipenem/imipenem-EDTA combined-disk ...
A highly carbapenem-resistant Pseudomonas aeruginosa isolate with a novel bla(VIM-4)/bla(P1b) integron overexpresses two efflux pumps and lacks OprD
(2007)
Objectives: A Pseudomonas aeruginosa clinical isolate that exhibited high-level carbapenem resistance and produced metallo-beta-lactamase (MBL) was recovered from a Greek patient. This study was conducted to determine the ...
Dissemination of clonally unrelated erythromycin- and glycopeptide-resistant Enterococcus faecium isolates in a tertiary Greek hospital
(2001)
Between September 1999 to February 2001, 25 glycopeptide-resistant Enterococcus faecium (GRE) isolates were recovered from a Greek hospital. The isolates exhibited 13 distinct chromosomal macrorestriction types by pulsed-field ...
Association of biofilm formation and methicillin-resistance with accessory gene regulator (agr) loci in Greek Staphylococcus aureus clones
(2009)
Pathogenicity of Staphylococcus aureus is coordinated by the accessory gene regulator (agr) system. Previous studies suggested that agr Group 11 methicillin-resistant S. aureus (MRSA), a polymorphism that has been associated ...
Low genetic diversity of the intrinsic OXA-51-like class D carbapenemases among Acinetobacter baumannii clinical isolates in Greece
(2007)
This study examined the geographical distribution and diversity of the intrinsic OXA-51-like class D carbapenemases among Acinetobacter baumannii clones recovered in three major Greek regions from 2000 to 2005. The bla(OXA-66) ...
Novel variant (bla(VlM-4)) of the metallo-beta-lactamase gene bla(VIM-1) in a clinical strain of Pseudomonas aeruginosa
(2002)
A Pseudomonas aeruginosa isolate highly resistant to carbapenems was collected from a patient with post-surgical cerebrospinal infection in Greece. The isolate carried a class I integron that contained as a sole cassette ...
Clonal spread of KPC-2 carbapenemase-producing Klebsiella pneumoniae strains in Greece
(2009)
KPC-possessing Klebsiella pneumoniae have been found to be widespread in several regions but are still rarely detected in Europe. We describe the characteristics of an outbreak caused by KPC producers in a tertiary care ...
