Abstract
During March and April 2024, we studied dairy cattle specimens from a single farm in Texas, USA, using multiple molecular, cell culture, and next-generation sequencing pathogen detection techniques. Here, we report evidence that highly pathogenic avian influenza A(H5N1) virus strains of clade 2.3.4.4b were the sole cause of this epizootic.
摘要
2024 年 3 月至 4 月期间，我们使用多种分子、细胞培养和下一代测序病原体检测技术，对来自美国德克萨斯州一个单一农场的奶牛标本进行了研究。在这里，我们报告了证据，表明 2.3.4.4b 分支的高致病性禽流感 A(H5N1)病毒株是这次疫情的唯一原因。
