We characterized isolates from porcine respiratory and reproductive syndrome virus epidemics in Vietnam and China in 2007. These isolates showed approximately 99% identity at the genomic level. Genetic analysis indicated that they share a discontinuous deletion of 30 aa in nonstructural protein 2, which indicates that identical variants emerged in Vietnam and China.
我们对2007年越南和中国猪繁殖与呼吸综合征病毒疫情中的分离株进行了特征分析。这些分离株在基因组水平上显示出约99%的同一性。遗传分析表明，它们在非结构蛋白2中共有一个30个氨基酸的间断性缺失，这表明在越南和中国出现了相同的变异株。
