چکیده انگلیسی
Avian influenza viruses (AIVs) are genetically separated by geographical barriers, resulting in the independent evolution of North American and Eurasian lineages. In the present study, to determine whether AIVs possessing the North American-origin nonstructural (NS) gene were previously introduced into South Korea, we performed a genetic analysis of AIVs isolated from fecal samples of migratory birds. We detected seven viruses possessing the North American-origin NS allele B among 413 AIV-positive samples obtained during AI surveillance between 2012 and 2017. We found evidence for the intercontinental transmission of at least three genetically distinct clusters of the B allele of the North American-origin NS gene into Eurasia at a low frequency. The host species of three viruses were identified as the greater white-fronted goose (Anser albifrons) using a DNA barcoding technique. Moreover, we used GPS-CDMA-based telemetry to determine the migration route of the greater white-fronted goose between the Far East of Russia and South Korea and found that this species may play an important role as an intermediate vector in the intercontinental transmission of AIVs. To improve our understanding of the role of wild birds in the ecology of AIVs, advanced AIV surveillance is required in the Far East of Russia as well as in Alaska region of Beringia accompanied by host identification and wild bird tracking.
