摘要 本研究对3例急性弛缓性麻痹患者标本的阳性病毒分离物进行了分子生物学定型。按照文献报道的方法,用扩增人类肠道病毒(Human Enterovirus,HEV)VP1完整编码区通用引物008-013、011-012进行逆转录-聚合酶链反应,反应产物纯化后进行序列测定。所得序列通过BLAST程序进行基因定型,显示3株病毒分别为HEV B组中新型病毒HEV73、HEV75和HEV97。将获得的序列与GenBank数据库中已有的各型病毒株VP1基因序列进行同源性分析并构建系统发生树,结果显示与各自的原型株相比有较大的变异,提示本次发现的HEV B组73、75、97型山东地方株与各型原型株相比具有不同的基因特征,这是在国内首次发现HEV97。 Molecular typing was conducted for three human enteroviruses （HEV） isolated from acute flaccid paralysis （AFP） cases in Shandong province, China. RNAs from virus supernatants were extracted and complete VP1 genes were amplified by RT-PCR and sequenced. Genotypes of these isolates were identified as HEV type 73, 75 and 97, respectively by BLAST program. Homology and phylogenetic tree analyses were performed. Sequence analysis of VP1 gene showed significant variation compared with prototype strains. This study presents the genetic characteristics of HEV 73, 75 and 97 of specie 13 in Shandong Province, and the first report of HEV97 in China.
