Carriage of OXA-58 but not of OXA-51 beta-lactamase gene correlates with carbapenem resistance in Acinetobacter baumannii
Tsakris, A.; Ikonomidis, A.; Pournaras, S.; Spanakis, N.; Markogiannakis, A. (2006) -
Characterization of clinical isolates of Pseudomonas aeruginosa heterogeneously resistant to carbapenems
Pournaras, S.; Ikonomidis, A.; Markogiannakis, A.; Spanakis, N.; Maniatis, A. N.; Tsakris, A. (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 ... -
Characterization of In3Mor, a new integron carrying VIM-1 metallo-beta-lactamase and sat1 gene, from Morganella morganii
Tsakris, A.; Ikonomidis, A.; Spanakis, N.; Poulou, A.; Pournaras, S. (2007)Objectives: A carbapenem-resistant Morganella morganii clinical isolate that was phenotypically metallo-beta-lactamase (MBL)-positive was recovered from a Greek patient. The aim of the study was to analyse the structure ... -
Clusters of imipenem-resistant Acinetobacter baumannii clones producing different carbapenemases in an intensive care unit
Tsakris, A.; Ikonomidis, A.; Poulou, A.; Spanakis, N.; Vrizas, D.; Diomidous, M.; Pournaras, S.; Markou, F. (2008)During a 2-year period (April 2005-March 2007), 31 intensive care unit (ICU) patients in a Greek hospital were infected or colonised with imipenem-resistant isolates of Acinetobacter baumannii. Twelve patients died, with ... -
Efflux system overexpression and decreased OprD contribute to the carbapenem heterogeneity in Pseudomonas aeruginosa
Ikonomidis, A.; Tsakris, A.; Kantzanou, M.; Spanakis, N.; Maniatis, A. N.; Pournaras, S. (2008)Pseudomonas aeruginosa strains exhibiting a heterogeneous mode of growth against carbapenems have been described recently. This study investigated the underlying molecular mechanisms in four genetically unrelated P. ... -
Emergence of carbapenem-resistant enterobacter cloacae carrying VIM-4 metallo-beta-lactamase and SHV-2a extended-spectrum beta-lactamase in a conjugative plasmid
Ikonomidis, A.; Spanakis, N.; Poulou, A.; Pournaras, S.; Markou, F.; Tsakris, A. (2007)Enterobacter cloacae strains are still infrequently resistant to carbapenems. A carbapenem-resistant clinical isolate of E. cloacae producing a plasmid-mediated metallo-beta-lactamase (MBL), VIM-4, was recovered from a ... -
Identification of a novel bla(OXA-51) variant, bla(OXA-92), from a clinical isolate of Acinetobacter baumannii
Tsakris, A.; Ikonomidis, A.; Spanakis, N.; Pournaras, S.; Bethimouti, K. (2007) -
Large Dissemination of VIM-2-Metallo-beta-Lactamase-Producing Pseudomonas aeruginosa Strains Causing Health Care-Associated Community-Onset Infections
Tsakris, A.; Poulou, A.; Kristo, I.; Pittaras, T.; Spanakis, N.; Pournaras, S.; Markou, F. (2009)During a 3-year period (May 2005 to April 2008), a series of 45 outpatients presented with community-onset urinary tract infections due to carbapenem-resistant Pseudomonas aeruginosa isolates. Forty of them had a history ... -
Recurrent healthcare-associated community-onset infections due to Klebsiella pneumoniae producing VIM-1 metallo-beta-lactamase
Poulou, A.; Spanakis, N.; Pournaras, S.; Pitiriga, V.; Ranellou, K.; Markou, F.; Tsakris, A. (2010)To investigate the extrahospital dissemination of carbapenem-resistant Klebsiella pneumoniae isolates and the mechanisms of acquired resistance. Patients who were referred to the outpatient department of Serres General ... -
Spread of efflux pump-overexpressing, non-metallo-beta-lactamase-producing, meropenem-resistant but ceftazidime-susceptible Pseudomonas aeruginosa in a region with bla(VIM) endemicity
Pournaras, S.; Maniati, M.; Spanakis, N.; Ikonomidis, A.; Tassios, P. T.; Tsakris, A.; Legakis, N. J.; Maniatis, A. N. (2005)Objectives: To investigate the resistance mechanisms of meropenem-resistant, ceftazidime-susceptible Pseudomonas aeruginosa isolates, in a clinical setting where VIM-2 or VIM-4 metallo-beta-lactamase (MBL)-producing ... -
Transmission in the community of clonal Proteus mirabilis carrying VIM-1 metallo-beta-lactamase
Tsakris, A.; Ikonomidis, A.; Poulou, A.; Spanakis, N.; Pournaras, S.; Markou, F. (2007)Objectives: Several infections among patients attending our outpatient clinic were caused by imipenem-resistant Proteus mirabilis that were phenotypically metallo-beta-lactamase (MBL)-positive. The aim of the study was to ... -
VIM-12, a novel plasmid-mediated metallo-β-lactamase from Klebsiella pneumoniae that resembles a VIM-1/VIM-2 hybrid
Pournaras, S.; Ikonomidis, A.; Tzouvelekis, L. S.; Tokatlidou, D.; Spanakis, N.; Maniatis, A. N.; Legakis, N. J.; Tsakris, A. (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 ...
