荧光定量PCR技术在霍乱弧菌检测中的应用*

Application of fluorescence quantitative PCR in detection of vibrio cholerae

  • 摘要:
      目的   建立霍乱弧菌荧光定量聚合酶链反应检测方法, 评价其优越性。
      方法   根据霍乱弧菌NhaA基因保守序列, 设计合成霍乱弧菌FQ-PCR诊断试剂盒, 比较该方法与常规检测方法在外环境、海产品及临床病例霍乱弧菌检测上的灵敏度和特异性。
      结果   在临床患者标本霍乱弧菌的检测上, FQ-PCR与常规方法灵敏度、特异性一致, 但在含菌量少、菌株易发生变异(外环境疫水、海产品及霍乱越冬)标本的检测上, FQ-PCR显示出其独特的优越性。
      结论   FQ-PCR方法用于霍乱弧菌的检测, 不仅可避免常规PCR引起的假阳性污染, 同时可实现对含菌量少、变异菌株的定量定时检测, 对临床检验及卫生检测有较大的指导意义。

     

    Abstract:
      Objective   To construct the detection method of vibrio cholerae with fluorescence quantitative PCR and evaluate its superiority.
      Methods   A diagnostic kit(FQ-PCR)was developed according to the common sequence of NhaA gene in vibrio cholerae.The sensitivity and speciality in detecting of vibrio cholerae in infectious water, sea food and winter-endurance specimen and clinical samples were compared with FQ-PCR kit.
      Results   In the detection of clinical samples, FQPCR and regular detection ways have the same sensitivity and speciality.While in the detection of infectious water, sea food and winter-endurance specimen, FQ-PCR has superiority to regular ways.
      Conclusion   The construction of FQ-PCR method eliminates PCR cross-contamination which cause false positive, and real-time detection ensure accurate quantity.So FQ-PCR can be used to the detection of vibrio cholerae in clinical and sanitary laboratory.
