Characterization of novel intergenogroup and intergenotype recombinant noroviruses from central Greece
(2014)Noroviruses (NoVs) are a major causative agent of acute gastroenteritis in humans. They are members of the Caliciviridae family and based on the genetic analysis of the RdRp and capsid regions, human NoVs are divided into ... -
Clonality of slime-producing methicillin-resistant coagulase-negative staphylococci disseminated in the neonatal intensive care unit of a university hospital
(2006)Methicillin-resistant coagulase-negative staphylococci (MR-CNS) (n = 132), isolated from pre-term neonates, were analysed to determine their antibiotic resistance patterns, clonal distribution, biofilm production and the ... -
Clusters of imipenem-resistant Acinetobacter baumannii clones producing different carbapenemases in an intensive care unit
(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 ... -
Comparative Evaluation of Combined-Disk Tests Using Different Boronic Acid Compounds for Detection of Klebsiella pneumoniae Carbapenemase-Producing Enterobacteriaceae Clinical Isolates
(2011)The accurate phenotypic detection of Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae is an increasing necessity worldwide. We evaluated the performance of boronic acid combined-disk tests using as ... -
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 ... -
Emergence of carbapenem-resistant enterobacter cloacae carrying VIM-4 metallo-beta-lactamase and SHV-2a extended-spectrum beta-lactamase in a conjugative plasmid
(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 ... -
Evolution of multidrug-resistant Acinetobacter baumannii clonal lineages: a 10 year study in Greece (2000-09)
(2011)Objectives: To analyse the evolution and genetic relatedness of Acinetobacter baumannii clonal lineages in Greece during a 10 year period. Methods: The study included 94 randomly selected A. baumannii clinical isolates ... -
Heteroresistance to Meropenem in Carbapenem-Susceptible Acinetobacter baumannii
(2009)The characteristics of carbapenem heteroresistance were studied in 14 apparently carbapenem-susceptible Acinetobacter baumannii isolates. The MICs for carbapenems were determined, and the isolates were genotyped by ... -
Identification and characterization of genetic structures coding for carbapenemases in enterobacteria from Central Greece
(2015)The dissemination of carbapenemases among different species of Enterobacteriaceae was investigated in the University Hospital of Larissa, Central Greece. The presence of the isoform (Tn4401a) of the transponson carrying ... -
Large Dissemination of VIM-2-Metallo-beta-Lactamase-Producing Pseudomonas aeruginosa Strains Causing Health Care-Associated Community-Onset Infections
(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 ... -
Macrolide resistance determinants among Streptococcus pneumoniae isolates from carriers in Central Greece
(2012)Background: We sought to characterize the temporal trends in nasopharyngeal carriage of macrolide-resistant pneumococci during a period with increased heptavalent pneumococcal conjugate vaccine (PCV7) coverage in Central ... -
Single-Locus-Sequence-Based Typing of bla(OXA-51-like) Genes for Rapid Assignment of Acinetobacter baumannii Clinical Isolates to International Clonal Lineages
(2014)Single-locus bla(OXA-51-like) sequence-based typing (SBT) was evaluated for its ability to determine correctly sequence types (STs) in Acinetobacter baumannii clinical isolates, in comparison with the Pasteur's multilocus ... -
Successful control of a neonatal outbreak caused mainly by ST20 multidrug-resistant SHV-5-producing Klebsiella pneumoniae, Greece
(2014)Background: Extended spectrum beta-lactamase-producing Klebsiella pneumoniae (ESBL-Kp) infection can cause significant morbidity and mortality in neonates. We investigated a nosocomial ESBL-Kp outbreak in a neonatal intensive ...
