RESUMO
Site-specific, risk-adjusted incidence rates of intensive care unit (ICU)-acquired infections were obtained through standardized surveillance in 8 ICUs in Greece. High rates were observed for central line-associated bloodstream infection (12.1 infections per 1,000 device-days) and ventilator-associated pneumonia (12.5 infections per 1,000 device-days). Gram-negative microorganisms accounted for 60.4% of the isolates recovered, and Acinetobacter species were predominant. To reduce infection rates in Greek ICUs, comprehensive infection control programs are required.

From 1,246 specimens collected from 13 Greek hospitals, 266 vancomycin-resistant enterococci strains were isolated from 255 patients (20.5%). The VanA phenotype was present in 82 (30.8%) strains, the VanB phenotype in 17 (6.4%) strains, the VanC1 phenotype in 152 (57.1%) strains, and the VanC2/C3 phenotypes in 15 (5.6%) strains. When only VanA and VanB phenotypes were considered, the overall prevalence was 7.5%. Eighty-six isolates exhibiting the VanA or VanB phenotype were analyzed by pulsed-field gel electrophoresis (PFGE), and 46 PFGE groups were found.
