摘要
目的建立风疹病毒的实时荧光PCR检测方法并应用于临床标本的快速检测。方法分析近四十年来流行的风疹病毒E1基因序列,设计用于病毒实时荧光PCR检测的引物和探针,建立风疹病毒实时荧光PCR检测方法。对30例临床诊断为风疹的患者标本进行实时荧光PCR检测,并与血清学检测结果进行比对。结果 30例患者标本中实时荧光PCR检测,27份阳性,3份阴性,阳性率为90.0%,远高于血清学检测(阳性率70.0%)。结论该方法具有方便快捷、特异性强、敏感性高等特点,为风疹病毒的快速诊断和分子流行病学调查提供了技术支撑。
Objective To establish a real-time PCR method for detection of rubella virus,and to apply it to rapid detection of clinical samples. Methods The real-time PCR primers probes were designed by analyzing E1 gene sequences of rubella virus found in recent 40 years,and then a real-time PCR method was established for detection of rubella virus in 30 clinically diagnosed rubella patients.Real-time PCR detection results of these patients were compared with the corresponding serological detection results. Results Among 30 specimens of the patients detected by real-time PCR,there were 27 positive samples and 3 negative ones.The positive rate was 90.0%,which was significantly higher than that of serological detection method（70.0%）. Conclusions The real-time PCR detection method has the advantages of convenience,higher specificity and sensitivity.It provides technical supports for rapid diagnosis and molecular epidemiological investigation of rubella virus.
