摘要: 目的 建立检测常见丝状真菌感染病原菌的PCR-RFLP和多重PCR方法。方法 建立以PCR技术为基础的限制片段长度多态性(RFLP)方法 ,首先用真菌通用引物扩增丝状真菌的ITS区,然后用限制性核酸内切酶对PCR产物进行酶切。用4种丝状真菌的特异性引物建立多重PCR体系,用该体系检测单模板、双模板和三模板的扩增情况,并测定该体系的特异性和敏感性。结果 用PCR-RFLP技术能够鉴别5种常见丝状真菌,多重PCR能够根据扩增片段的不同鉴别菌种,在合适的反应条件下,对单模板、双模板和三模板均能扩增出目的片段。结论 PCR-RFLP和多重PCR技术能够快速鉴定丝状真菌感染病原菌,有临床应用的良好前景。

Abstract: Objective To establish diagnositic methods for pathogenic molds using PCR-RFLP and multiplex PCR.Methods A PCR-based restriction fragment length polymorphism method was developed.ITS region of molds was amplified with universal fungal primers,and for RFLP analysis with restriction enzyme.Mutiplex PCR with 4 primer pairs was used to detect 1 template and 2 or 3 template mixtures.Sensitivity and specificity of multiplex PCR were measured.Results PCR-RFLP clearly differentiated the pathogenic molds.Multiplex PCR could amplify the corresponding 1,2 or 3 DNA fragments.Five molds were identified through distinct amplicons.Conclusions PCR-RFLP and multiplex PCR are rapid methods for the identification of pathogenic molds.

Key words: mold, PCR-RFLP, multiplex PCR, molecular identification
