摘要: ABSTRACT The present study was conducted to monitor wild birds based on the concern that they could disseminate avian influenza virus (AIV) between Mongolia and Korea, which shares same migratory flyway. Of 1,528 fecal samples analyzed, 21 low-pathogenic AIV were isolated from 2007 2009. Nineteen AIV-positive identified as Anseriformes by DNA bar coding. most frequently subtype H3 (61.9%), prevalent hemagglutinin/neuraminidase combination H3N8 (52.4%). Phylogenetic analysis performed assess their genetic relationships with those of domestic poultry in Korea. H7 surface genes belonged Eurasian lineage clustered together a group Korean poultry. Most N8 phylogenetically viruses Eurasia, whereas 1 Mongolian some North American lineage. polymerase acidic protein internal gene not distinguishable H5N1 highly pathogenic goose/Guangdong/1/1996 (Gs/Gd)-like virus. Our suggests isolates have evolved genetically multiple genotypes are closely related well
