摘要
[目的]为快速诊断土拉菌病拟建立套式PCR技术。[方法]设计出2对特异引物,取1986年1月收集的13名土拉菌病患者的抗凝血及对照组细菌,提取DNA并进行套式PCR扩增。[结果]套式PCR检测到患者血液中土拉菌阳性率为84.6%,对照组细菌均为阴性。用直接PCR能观察到10条位于900 bp的暗带。而行套式PCR后能观察到11条亮度较高为于550 bp处的条带。[结论]套式PCR方法检测土拉菌具有特异性强、敏感性高,简便快速的特点。
[Objective]To set up Nested PCR in diagnosing tularemia patients as soon as possible.[Methods]Thirteen subjects' blood was collected in Jan.of 1986 and was detected by Nested PCR in April of 2005.[Results]The positive rate of francisella tularensis was 84.6% in Nested PCR.[Conclusion]Nested PCR are convenient and precise for clinical application.
