The epidemic West Nile virus strain in Greece was a recent introduction.

To estimate the prevalence of West Nile virus (WNV) immunoglobulin G (IgG) antibodies in residents of northern Greece before the large outbreak of 2010, stored serum samples collected during 2003-2004 from 626 apparently healthy residents of northern Greece were tested. A seroprevalence of 0.62% was detected, with no statistically significant differences among the various prefectures, gender, and age groups, suggesting that the lineage 2 WNV strain that caused the outbreaks for 3 consecutive years was introduced recently.

Characterization of Enterobacteriaceae producing OXA-48-like carbapenemases in the UK.

Objectives: To characterize UK clinical isolates of Enterobacteriaceae producing OXA-48-like carbapenemases and to compare their resistance plasmids.

Methods: Twenty-six enterobacteria producing OXA-48-like enzymes were studied. These were from 22 diverse hospitals in the UK.
