Emergence of new phylogenetic lineage of Influenza D virus with broad antigenicity in California, United States

Influenza D virus (IDV), with bovines as a primary host, circulates widely in cattle populations across North America and Eurasia. Here we report the identification of a novel IDV group with broad antigenicity in U.S. bovine herds, which is genetically different from previously known lineages of IDV.

丁型流感病毒（Influenza D virus, IDV）以牛科动物为主要宿主，在北美及欧亚大陆的牛群中广泛流行。本研究报道了在美国牛群中鉴定获得的具有广谱抗原性的新型丁型流感病毒类群，该类群的遗传特征与此前已知的丁型流感病毒谱系存在显著差异。
