目的了解内蒙古自治区腮腺炎病毒基因特征,填补内蒙古自治区腮腺炎病原学监测工作空白。方法采集内蒙古通辽市一起腮腺炎暴发疫情中部分病例的咽拭子标本,进行腮腺炎病毒分离和病毒基因型别鉴定。结果 1份咽拭子标本腮腺炎病毒分离阳性,经序列分析病毒分离株鉴定为F基因型腮腺炎病毒。结论该次内蒙古自治区腮腺炎暴发疫情流行是由F基因型腮腺炎病毒引起的。目前,内蒙古自治区流行腮腺炎病毒为F基因型腮腺炎病毒。
Objective To understand the mumps virus gene characteristics in Inner Mongolia Autonomous Region and to fill the vacancy of mumps etiology monitoring in Inner Mongolia Autonomous Region. Methods Throat swab samples from some cases of mumps outbreak in Tongliao City of Inner Mongolia were collected for mumps virus isolation and virus genotyping. Results A throat swab specimen was positive for mumps virus. The virus isolate was identified as F genotype mumps virus by sequence analysis. Conclusions The outbreak of mumps outbreak in Inner Mongolia Autonomous Region was caused by the F genotype mumps virus. At present, the epidemic mumps virus in Inner Mongolia is the F genotype mumps virus.
