摘要
Objective:To present results of virological study of wild birds inhabiting Western Mongolia. Methods:Over a period of 2003-2008,we isolated 13 influenza A viruses:H1N1,H3N6, H13N8 and H4N6 subtypes.We did not isolate any H5N1 subtype,that still cause epizooty in wild birds and poultry.Results:We revealed taxonomic and ecological heterogeneity of the birds involved in maintenance of circulation of influenza viruses in the given territory.Influenza viruses were isolated from birds of 6 orders;among them there are species preferring water and semi-aquatic biotopes,one species preferring dry plain region,and also one species which can inhabit both dry and water biotopes.Conclusions:Representatives of all main orders of Western Mongolia avifauna are involved in support of influenza A virus circulation,highly pathogenic H5N1 influenza viruses were registered in Mongolia thus it’s necessary to continue permanent influenza virus surveillance in wild birds’ populations.
