Polymerase chain reaction was utilized to determine the sequence of a 280 base pair fragment from cDNAs of the 5' noncoding region of 29 isolates of classical swine fever virus. Phylogenetic analysis of the sequences revealed low level genomic variation that correlated with the geographic origins of the isolates.
利用聚合酶链反应确定了29株经典猪瘟病毒5'非编码区cDNA中一个280碱基对片段的序列。对这些序列的系统发育分析显示,低水平的基因组变异与分离株的地理来源相关。
