摘要: 摘要: 目的建立小鼠微小病毒( MVM) 荧光定量PCR 方法,并初步应用于实验小鼠中。方法根据NCBI 上发表的MVM( NC_001510) 基因组序列,设计引物和探针,建立MVM 荧光定量PCR 方法。考察引物探针的最佳线形范围,特异性及灵敏度,并使用该方法对178 份清洁级小鼠粪便DNA 样本进行检测。结果MVM 荧光定量PCR 方法最佳线性范围为109 ~ 104 拷贝/μL,标准曲线的线性关系良好,R2 值可达0. 99,灵敏度为101 拷贝/μL,特异性强,与大鼠细小病毒H-1 株和KRV 株、猪细小病毒均无交叉反应。应用荧光定量PCR 方法对178 份小鼠粪便DNA进行检测,结果均为阴性。结论建立的MVM 荧光定量PCR 方法具有特异、灵敏的特点,为MVM 的流行病学调查、检测提供了有效的技术支持。

Abstract: Abstract: Objective To establish and preliminarily apply the real-time PCR for detecting minute virus of mice ( MVM) . Method According to the genome sequences of MVM( NC_001510) from NCBI,one pairs of primers and probes were designed. The linearity,specificity,and sensitivity of the method were investigated. 178 mouse faeces DNA were detected by the real-time PCR. Result The real-time PCR for detecting MVM showed a linear range of 1x109 ~ 1x104copies /μL,high specificity,which showed no cross-reaction with rat parvovirus H1,KRV and porcine parvovirus. The sensitivity of the real-time PCR was 101copies /μL. The real-time PCR detecting results of 178 clean grade mouse faeces were that all of them were MVM negative. Conclusion The real-time PCR method is good in specificity,sensitivity,which can make a powerful technical support for MVM epidemiological investigation and detection.
