摘要: 根据Q热贝纳柯克斯体(Coxiella burnetii)插入序列IS1111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102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 Green Ⅰ荧光定量PCR法灵敏度高且特异性好,可用于临床检测。

Abstract: Primers were designed based on insert sequence IS1111 of Coxiella bumetii of Q fever, SYBR GreenⅠReal-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 102 of the plasmid copy numbers.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,Chlamydia,Brucella and bovine blood were negative. SYBR GreenⅠfluorescent quantitative PCR method developed in this study had high Brucella sensitivity and specificity,and could be used for clinical test.

Key words: Q fever; Coxiella burnetii; Real-time quantitative PCR; SYBR GreenⅠdye method
