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 ...
Prognostic value of follicular fluid 25-OH vitamin D and glucose levels in the IVF outcome
(2010)
Objectives: The aim of the present study was to measure serum and follicular fluid 25-OH vitamin D and glucose levels in women who underwent IVF-ET treatment and to further investigate whether the circulating 25-OH vitamin ...
Angiopoietin-1 and angiopoietin-2 as serum biomarkers for ectopic pregnancy and missed abortion A case-control study
(2013)
Background: A case-control study to evaluate whether a single serum measurement of angiopoietin-1 (ANG-1) and angiopoietin-2 (ANG-2) at 6-8 weeks gestation can differentiate failed pregnancies, whether ectopic pregnancies ...
Predictors of mortality in patients with bloodstream infections caused by KPC-producing Klebsiella pneumoniae and impact of appropriate antimicrobial treatment
(2011)
Bloodstream infections (BSIs) caused by Klebsiella pneumoniae carbapenemases (KPC)-producing K. pneumoniae (KPC-KP) are associated with high mortality rates. We investigated outcomes, risk factors for mortality and impact ...
Trends in antimicrobial resistance of clinical isolates of Enterococcus faecalis and Enterococcus faecium in Greece between 2002 and 2007
(2010)
We analysed trends in antimicrobial resistance of Enterococcus faecalis (N = 1498) and E. faecium (N = 625) recovered from clinical infections during 2002-2007 in a Greek tertiary care hospital. Molecular assays were used ...
The Indoleamine 2,3-dioxygenase Inhibitor 1-methyl-tryptophan Suppresses Mitochondrial Function, Induces Aerobic Glycolysis and Decreases Interleukin-10 Production in Human Lymphocytes
(2012)
Background: Indoleamine 2,3-dioxygenase (IDO) suppresses adaptive immunity. It is known that IDO induces T-cell differentiation to regulatory T-cells (Treg) through tryptophan depletion and/or kynurenine pathway products. ...
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 ...
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 ...
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 ...
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) ...
