Nineteen of 27 ceftazidime-resistant Enterobacter cloacae isolates from a neonatal intensive care unit in Thessaloniki, Greece, had genes coding for the novel extended-spectrum beta-lactamase IBC-1; 18 of those 19 harbored similar conjugative plasmids and belonged to two distinct genetic lineages. A synergy test with ceftazidime and imipenem enabled us to(More)
Sir, The emergence of vancomycin-resistant enterococci (VRE) has raised major concerns because of the limited therapeutic options for treating infections resulting from these organisms. In the USA, the National Nosocomial Surveillance System has described a 20-fold rise in VRE recovered from bloodstream infections during the past 10 years. The limitation in(More)
A sample of 450 consecutive, non-replicated coagulase-negative staphylococci (CoNS), collected from clinical specimens during the period 2000-2001 from the five major hospitals of Thessaly district (Central Greece) were investigated for resistance to methicillin. Most of the isolates had been collected in a sporadic fashion from the intensive care units and(More)
Seventy-six nontuberculous mycobacterial isolates obtained from patients living in Greece were analyzed with the GenoType Mycobacterium CM (for common mycobacteria) and AS (for additional species) assays. GenoType correctly identified all but one of the mycobacterial species. For this species, additional probes should be designed and added to the strip.
The aim of this retrospective study was to evaluate melanoma biopsy specimens from the Greek population living in the prefecture of Larissa for the presence of human papillomavirus (HPV) DNA and to determine the possible relationship between HPV and clinical outcome in these patients. Twenty-eight melanoma biopsy specimens, 20 from primary cutaneous(More)
One hundred and fifty clinical isolates of Mycobacterium tuberculosis were tested for susceptibility to pyrazinamide using the fully automated Bactec MGIT 960 system and the radiometric Bactec 460TB system. The overall concordance rate between MGIT 960 and radiometric system was 100% and the mean turnaround times to report the susceptibility test results(More)

OBJECTIVES To determine the rates of mupirocin resistance in staphylococci during a 4 year period (1999-2002) in Greece. MATERIALS A total of 1200 Staphylococcus aureus and 2760 coagulase-negative staphylococci (CoNS), consecutively collected from four Greek hospitals located in different geographical areas, were tested for susceptibility to mupirocin(More)
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 gel electrophoresis, and all were erythromycin and vancomycin resistant, carrying the genes vanA and ermB. Vancomycin resistance,(More)
