Influenza A Virus in Wild Bird Populations in the South of Western Siberia (2009-2010)
The results of the study of influenza A virus in wild bird populations in the south of Western Siberia in 2009-2010 are presented. The urgency and importance of study of influenza virus in wild birds in the south of Western Siberia is shown to assess the epidemiological situation. Our research marked the importance of different groups of wild birds in the persistence of the different influenza viruses in Western Siberia. A wide variety of subtypes was shown circulating in wild birds in the area. We studied the rare subtypes of the virus and their molecular-biological properties. Phylogenetic analysis of the isolated strains showed ecological relation of viruses from south of Western Siberia with distant geographical areas.
