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 *** did not isolate any H5N1 subtype,that still cause epizooty in wild birds and ***:We revealed taxonomic and ecological heterogeneity of the birds involved in maintenance of circulation of influenza viruses in the given *** 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 ***: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.

Objective:To evaluate the use of Real-Time PCR system based on specific amplification of matrix protein gene fragment for influenza A virus RNA detection in cloacal swabs from wild ***:Sensitivity,specificity and reproducibility of analysis results were identified. Study of cloacal swabs from wild birds for influenza A virus presence was ***: Reproducibility of low concentrations of virus detection in samples by Real-Time PCR was significantly higher than that of detection based on cytopathic effect of viruses grown on MDCK cell ***:Real-Time PCR system for influenza A virus RNA detection is developed and applied for virus surveillance study.

A novel Clade 2.***.2.1c H5N1 reassortant virus caused several outbreaks in wild birds in some regions of China from late 2014 to *** on the genetic and phylogenetic analyses,the viruses possess a stable gene constellation with a Clade 2.***.2.1c HA,a H9N2-derived PB2 gene and the other six genes of Asian *** Clade 2.***.2.1c H5N1 reassortants displayed a high genetic relationship to a human H5N1 strain(A/Alberta/01/2014).Further analysis showed that similar viruses have been circulating in wild birds in China,Russia,Dubai(Western Asia),Bulgaria and Romania(Europe),as well as domestic poultry in some regions of *** affected areas include the Central Asian,East Asian-Australasian,West Asian-East African,and Black Sea/Mediterranean *** results show that the novel Clade 2.***.2.1c reassortant viruses are circulating worldwide and may have gained a selective advantage in migratory birds,thus posing a serious threat to wild birds and potentially humans.
