⑤NA genetic evolution indicates that the NA genes with H5N2 subtypes of wild birds in North America are highly homologous to those of poultry H5N1 subtypes in mainland China. The results suggest that the global prevalence of H5N2 subtype AIV is increasing, and that wild birds with ...
为了建立适用于临床诊断的H1N1亚型猪流感病毒快速检测方法,本研究根据GenBank已登录的H1N1亚型猪流感病 毒HA和NA基因序列设计RT-PCR扩增引物,以H1N1亚型猪流感病毒、H3N2亚型猪流感病毒、猪瘟病毒和猪繁殖与呼吸综 合征病毒为试验对照,通过优化RT-PCR反应条件和反应体系,建立了H1N1亚型猪流感病毒HA和NA基因双重RT-PCR...
Compared with the vaccine strains, there were no statistically significant of HA and NA genes and amino acid sequences of influenza A viruses in immunosuppressed and immunocompetent patients. However, the oseltamivir resistance substitution of NA-H275Y and R292K have been observed in immunosuppressed...
