Phylogenetic analyses of foot-and-mouth disease type A viruses in the Middle East during 2015-2016 identified viruses belonging to the A/ASIA/G-VII lineage, which originated in the Indian subcontinent. Changes in a critical antigenic site within capsid viral protein 1 suggest possible evolutionary pressure caused by an intensive vaccination program.
2015-2016 年期间中东地区的口蹄疫 A 型病毒的系统进化分析鉴定出属于 A/ASIA/G-VII 谱系的病毒,该谱系起源于印度次大陆。衣壳病毒蛋白 1 内一个关键抗原位点的变化表明,密集的疫苗接种计划可能导致了进化压力。
