Highly pathogenic avian influenza virus (H5N1) (QH09) was isolated from dead wild birds (3 species) in Qinghai, China, during May-June 2009. Phylogenetic and antigenic analyses showed that QH09 was clearly distinguishable from classical clade 2.2 viruses and belonged to clade 2.3.2.
高致病性禽流感病毒(H5N1)(QH09)于 2009 年 5 月至 6 月在中国青海从死亡野生鸟类(3 种)中分离得到。系统发育和抗原性分析表明,QH09 与经典 2.2 分支病毒明显不同,属于 2.3.2 分支。
