Acquired carbapenemases in Gram-negative bacterial pathogens: detection and surveillance issues
(2010)Acquired carbapenemases are emerging resistance determinants in Gram-negative pathogens, including Enterobacteriaceae, Pseudomonas aeruginosa and other Gram-negative non-fermenters. A consistent number of acquired ... -
Antibacterial Activity of Greek and Cypriot Honeys Against Staphylococcus aureus and Pseudomonas aeruginosa in Comparison to Manuka Honey
(2013)The antibacterial activity of 31 Greek and Cypriot honeys against Staphylococcus aureus and Pseudomonas aeruginosa was initially screened using an agar-well diffusion assay in comparison with manuka honey. The minimum ... -
Bacterial live vaccines with graded level of attenuation achieved by antibiotic resistance mutations: transduction experiments on the functional unit of resistance, attenuation and further accompanying markers
(1998)At least 10% of spontaneous chromosomal antibiotic resistant mutants of bacteria express a strain-dependent graded reduction of virulence; this correlates linearly with a prolonged generation time. Occasionally, these ... -
Bather density as a predominant factor for health effects related to recreational bathing: Results from the Greek bathers cohort study
(2011)Our aim was to examine the health effects on bathers from exposure to recreational seawater on three beaches with different microbiology quality and bather density through a cohort study. An initial questionnaire and a 10 ... -
Characteristics of Meropenem Heteroresistance in Klebsiella pneumoniae Carbapenemase (KPC)-Producing Clinical Isolates of K-pneumoniae
(2010)Meropenem heteroresistance was investigated in six apparently meropenem-susceptible, Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae (KPC-KP) clinical isolates, compared with that in carbapenemase-negative, ... -
Characterization of In3Mor, a new integron carrying VIM-1 metallo-beta-lactamase and sat1 gene, from Morganella morganii
(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 ... -
Characterization of Metallo-beta-Lactamase VIM-27, an A57S Mutant of VIM-1 Associated with Klebsiella pneumoniae ST147
(2011)VIM-27 metallo-beta-lactamase, an Ala(57) -> Ser variant of VIM-1, was identified in three Klebsiella pneumoniae isolates belonging to sequence type 147. bla(VIM-27) was part of a class 1 integron carried by non-self-transferable ... -
Clindamycin binding to ribosomes revisited: foot printing and computational detection of two binding sites within the peptidyl transferase center
(2013)Clindamycin is a semi-synthetic lincosamide, active against most Gram-positive bacteria and some protozoa. It binds to the 50S ribosomal subunit and inhibits early peptide chain elongation. By kinetic analysis it has been ... -
Combined prediction of Tat and Sec signal peptides with hidden Markov models
(2010)Motivation: Computational prediction of signal peptides is of great importance in computational biology. In addition to the general secretory pathway ( Sec), Bacteria, Archaea and chloroplasts possess another major pathway ... -
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 ... -
Confronting carbapenemase-producing Klebsiella pneumoniae
(2013)The ongoing spread of carbapenemase-producing (CP) multidrug-resistant enterobacteria, primarily Klebsiella pneumoniae, has undoubtedly caused a public health crisis of unprecedented dimensions. The scientific community ... -
Conjugation with polyamines enhances the antibacterial and anticancer activity of chloramphenicol
(2014)Chloramphenicol (CAM) is a broad-spectrum antibiotic, limited to occasional only use in developed countries because of its potential toxicity. To explore the influence of polyamines on the uptake and activity of CAM into ... -
CTX-M-1 extended-spectrum beta-lactamase-producing Proteus mirabilis in Greece
(2005)To examine the dissemination of CTX-M-type extended-spectrum beta-lactamases (ESBLs) in clinical isolates of Proteus mirabilis, 91 nonrepetitive ESBL-producing P. mirabilis were collected from infected patients in a tertiary ... -
Dissemination of Clinical Isolates of Klebsiella oxytoca Harboring CMY-31, VIM-1, and a New OXY-2-Type Variant in the Community
(2011)The aim of the present study was to investigate the epidemiological link of multidrug-resistant Klebsiella oxytoca isolates causing community-onset infections among patients attending our outpatient department and to ... -
Efficient soluble expression of active recombinant human cyclin A2 mediated by E. coli molecular chaperones
(2015)Bacterial expression of human proteins continues to present a critical challenge in protein crystallography and drug design. While human cyclin A constructs have been extensively characterized in complex with cyclin dependent ... -
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 ... -
Evaluation of Boronic Acid Disk Tests for Differentiating KPC-Possessing Klebsiella pneumoniae Isolates in the Clinical Laboratory
