Abstract
We isolated two highly pathogenic avian influenza viruses (HPAIVs) of subtype H5N8 clade 2.3.4.4b from falcated duck () feces and environmental water collected at an overwintering site in Japan. Our isolates were almost genetically identical to each other and showed high genetic similarity with H5N8 HPAIVs recently isolated in South Korea, a distant part of Japan, and European countries. These results suggest the potential role of falcated ducks in the dissemination of HPAIVs.
摘要
我们从日本一个越冬地采集的罗纹鸭粪便和环境水样中分离出两株2.3.4.4b分支的H5N8亚型高致病性禽流感病毒（HPAIVs）。我们的分离株在基因上几乎彼此相同，并且与最近在韩国、日本遥远地区以及欧洲国家分离出的H5N8 HPAIVs具有高度的基因相似性。这些结果表明罗纹鸭在HPAIVs传播中可能发挥的作用。
