This study describes the genetic characterization of avian influenza virus from waterfowl in Mexico. Partial sequences of two H5, one H6, and one H9 hemmaglutinin (HA) genes were determined. The deduced amino acid sequences showed that they were low-pathogenic viruses (LPAI). Phylogenetic analysis of H5 and H6 HA indicates a North American lineage, closely related to contemporary Californian isolates, and H9 HA was closer to the Korean-like lineage. These results demonstrate the introduction of a diverse genetic pool of subtypes to Sonora estuaries through circulation of bird species carriers from the Pacific flyway.
本研究描述了来自墨西哥水禽的禽流感病毒的遗传特征。测定了两个 H5、一个 H6 和一个 H9 血凝素 (HA) 基因的部分序列。推导的氨基酸序列表明它们是低致病性病毒 (LPAI)。H5 和 H6 HA 的系统发育分析表明，它们属于北美的谱系，与加利福尼亚州的当代分离株密切相关，而 H9 HA 则更接近韩国类似的谱系。这些结果表明，通过来自太平洋迁徙路线的鸟类携带者的循环，将多种遗传亚型引入到了索诺拉河口。
