摘要

目的建立一种多重实时荧光定量PCR法,同时检测常见蜱传病原体嗜吞噬细胞无形体、伯氏疏螺旋体及斑点热群立克次体（SFGR）。方法针对各病原体的保守区序列设计特异性引物及TaqMan探针,建立并优化多重实时荧光定量PCR反应体系,评价方法的特异性、灵敏度、重复性及对蜱样本的检测准确性。结果建立的多重实时荧光定量PCR法检测嗜吞噬细胞无形体、伯氏疏螺旋体、SFGR,与大肠埃希菌、问号钩端螺旋体、布鲁氏菌等病原体间无交叉反应,特异性良好；灵敏度均达到10²拷贝/μl,重复性变异系数均<2.00％；蜱样本检测中,多重实时荧光定量PCR法与单重实时荧光定量PCR法检测结果一致性为100%。结论研究建立的3种蜱传细菌性病原体多重实时荧光定量PCR法特异性好、灵敏度高,为蜱传病原体的检测提供了技术手段。

Abstract

Objective To establish a multiplex real-time fluorescence quantitative PCR (qPCR) method for simultaneous detection of the common tick-borne pathogens Anaplasma phagocytophilum, Borrelia burgdorferi, and spotted fever group Rickettsia (SFGR).Methods Specific primers and TaqMan probes were designed against the conserved regions of pathogens,and a multiplex qPCR system was established and optimized. The specificity, sensitivity, repeatability,and accuracy for tick samples were evaluated.Results There were no cross reactivity with Escherichia coli,Leptospira interrogans, Brucella sp. in the detection of A. phagocytophilum, B. burgdorferi, and SFGR by the established multiplex qPCR method and showed high specificity. The sensitivity reached the order of 10² copies/μl, and the coefficient of variation for repeatability was less than 2.00%. In tick sample detection, the results of multiplex qPCR method were consistent with the singleplex qPCR method, with 100% consistency.Conclusion The established multiplex qPCR method for three tick-borne bacterial pathogens has high specificity and sensitivity, and can be used as a technical means for the detection of common tick-borne bacterial pathogens.
