吉林省首次分离的流行性腮腺炎野病毒及基因型鉴定

Gene Identification of Mumps Wild Virus Isolated Firstly in Jilin Province

目的对吉林省2008年一起流行性腮腺炎(腮腺炎)爆发疫情进行病原学监测,观察是否出现典型的致细胞病变效应(Cytopathic Effect,CPE),并进行病毒核酸和基因型鉴定。方法采集病人的咽拭液,接种于生长良好的Vero/SLAM细胞(淋巴信号激活因子转染的非洲绿猴肾细胞),观察是否出现CPE,对三代病毒分离液采用逆转录-聚合酶链反应进行核酸鉴定,采用序列分析进行基因型鉴定。结果在采集到的15份标本中,有3份标本在Vero/SLAM细胞上可见到三种不同的典型CPE,6份标本核酸扩增为阳性,序列分析结果显示均为F基因型。结论在同一起爆发中,由同一株腮腺炎病毒引起的不同腮腺炎病例,虽然核苷酸序列完全一致,但所分离出的病毒在Vero/SLAM细胞上可表现为非常明显的不同类型的CPE。

Objective To observe Cytopathic Effect of wild-type mump viruses in Vero/SLAM cell and identify genotype in a mump outbreak in 2008. Methods Throat swabs were collected and to isolated mump virus with Vero/slam cells.Cytopathic effect was observed and determined mump virus type with Reverse Transcription- Polymerase Chain Reaction （RT-PCR）. Results Of the total 15 throat swabs, different CPE were observed in 3 throat swabs but genotypes are same, they are F type, 3 throat swabs were not observed cytopathic effect but genotypes were F type. Conclusion There were different kinds of cytopathic effect in one mump outbreak although genotypes were same.
