Abstract
We report full-genome characterization of highly pathogenic avian influenza A(H5N1) clade 2.3.4.4b virus from an outbreak among sea lions (August 2023) in Argentina and possible spillover to fur seals and terns. Mammalian adaptation mutations in virus isolated from marine mammals and a human in Chile were detected in mammalian and avian hosts.
摘要
我们报告了源自阿根廷海狮（2023 年 8 月）暴发的高致病性禽流感 A(H5N1) 2.3.4.4b 病毒的全基因组特征，该病毒可能溢出到海狗和燕鸥中。在智利从海洋哺乳动物和人类中分离到的病毒中检测到了哺乳动物适应突变，这些突变存在于哺乳动物和禽类宿主中。
