Aquatic birds are a reservoir of all known influenza A viruses. Avian influenza viruses have played a major role in the creation of pandemic influenza viruses in humans. In this study, we genetically characterized genes of nine isolates from waterfowl in Eulsukdo, a congregating place for migratory birds on the flyway of migration from Siberia, which is located in the southern part of South Korea. Phylogenic analysis showed that HA and NA genes of isolates belonged to Eurasian lineage, and lineage analysis showed that NS, PB1, PA, NP, and M genes of isolates clustered with Eurasian lineage, and PB2 genes of isolates belonged to North American or Eurasian lineage. Results suggest that the interregional transmission of genes of avian influenza viruses may occur in the migratory birds.

:水禽是所有已知的A型流感病毒的储存库。禽流感病毒在人类大流行性流感病毒的产生中发挥了重要作用。在这项研究中,我们通过遗传学鉴定了Eulsukdo的9种水禽分离株的基因,Eulsukdo是位于从西伯利亚迁徙的飞鸟聚集地,位于韩国南部。系统发育分析表明,分离株的HA和NA基因属于欧亚谱系,谱系分析表明,分离株的NS,PB1,PA,NP和M基因与欧亚谱系聚在一起,而分离株的PB2基因属于北美或欧亚谱系。 。结果表明,禽流感病毒基因的区域间传播可能发生在候鸟中。
