摘  要:
根据Q热贝纳柯克斯体(Coxiella burnetii)插入序列ISllll序列设计引物,建立快速检测Q热的SYBR GreenI实时荧光定量PCR方法.以梯度稀释的含有目的扩增片段的重组质粒作为标准品,进行定量PCR反应.结果显示,该方法能检测出10.个拷贝数的阳性质粒.标准曲线相关系数为0.991,扩增效率为98%.对结核分支杆菌、衣原体、布鲁氏杆菌及牛血液的核酸样品的特异性检测结果均为阴性.结果表明本研究建立的SYBR GreenI荧光定量PCR法灵敏度高且特异性好,可用于临床检测.

摘  要:
Primers were designed based on insert sequence ISl111 of Q fever Coxiella bumetii, SYBR Green Ⅰ Real-time quantitative PCR assay was developed for indentification of Q fever. The recombinant plasmid containing the target sequence was constructed to detect the sensitivity and prepare the standard curve. The method could detect 10z of the plasmid copy num- bers. Related coefficient was 0. 991 of the standard curve, the amplification efficiency was 98 %. The results of specific detection of nucleic acid sample for M. tuberculosis, Chlarnydia, Brucella and bovine blood were negative. SYBR Green I fluorescent quantitative PCR method developed in this study had high Brucella sensitivity and specificity, and could be used for clinical test.
