GENOTYPING OF INFLUENZA A VIRUSES ISOLATED FROM WILD BIRDS IN THE SOUTH OF WESTERN SIBERIA
During the surveillance study for avian influenza virus (AIV) in Western Siberia in 2011, 759 samples from wild birds of various orders were collected. Forty AIVs were isolated (isolation rate 5.27%). Viral subtypes were identified as follows: H?N1 (n=2), H?N8 (n=1), H1N1 (n=1), H3N1 (n=1), H3N2 (n=1), H3N6 (n=1), H3N8 (n=8), H4N6 (n=3), H4N? (n=3), H5N1 (n=3), H5N3 (n=1), H6N2 (n=1), H8N4 (n=2), H13N2 (n=3), H16N3 (n=3). Six isolates were unsubtyped. AIVs were isolated from white-headed duck (n=1), mallard (n=10), shoveler (n=2), European teal (n=19), garganey (n=1), common coot (n=1), common gull (n=6). The results of this study show the importance of West Siberian region in AIV circulation. These data can be used for further study of viral evolution and pathogen distribution during migration flights.
