"Aim of this study was to compare prevalence and characteristics of vanA-carrying vancomycin resistant enterococci (VRE) isolated from American crows (Corvus brachyrhynchos) and rooks (Corvus frugilegus) wintering in the United States, Canada, and various European countries. Samples of feces were collected during winters 2010-2013 and cultivated selectively for VRE. We tested susceptibility to other antibiotics by disk diffusion method and occurrence of resistance and virulence genes. Pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) were used to examine epidemiologic relationships of vanA-containing VRE. VRE with the vanA gene were found in 15 (2.5%) of 590 and one of 400 crow samples (0.3%) in the USA and Canada, respectively. In Europe, VRE with the vanA gene were found in 8 (0.7%) of 1073 rook samples. In total, we obtained 23 isolates of E. faecium and 8 E. faecalis. Based on MLST analysis, all E. faecium isolates belonged to clonal complex 17. All E. faecalis isolates were from USA and belonged to ST6 (1), ST16 (3) and ST179 (4). Clinically important enterococci with the vanA gene occurred in omnivorous corvids in North America and Europe. The role of migratory birds in dissemination of antibiotic resistant bacteria has not been understood yet, but presence of clinically important enterococci in corvids may pose a risk of environmental contamination."@en .
