[The 2003 results of monitoring of influenza A virus in the populations of wild birds in the south of Western Siberia].
The paper presents the results of isolation of influenza A virus from 97 cloacal swabs of 11 species of aquatic and semiaquatic wild birds collected on the Chany Lake (the south of Western Siberia, Ob-Irtysh interarea). Six strains with subtypes H2 (2 strains), H3 (3 strains), and H5 (1 strain) were isolated from mallard ducks (Anas platyrhynchos). The total infection rate in the examined birds was 6.2% and that in the ducks was 9.7%. The paper deals with the phylogenetic analysis of hemagglutinin of genes of isolates and with the comparison of the obtained results with the 2002 data in the same region. Analysis of H5 strain hemagglutinin proteolytic site permits one to regard this strain as non-pathogenic.
