    摘要:

    为了更加准确、快速地检测进出口食品中的副溶血性弧菌,针对副溶血性弧菌的tlh基因设计环介导等温扩增(loop-mediated isothermal amplification,LAMP)引物,结合ESEQuant tube scanner来对扩增结果进行实时检测。结果显示:该引物扩增效率高、特异性强、灵敏度高(1~10 CFU/反应,约为荧光PCR的100倍)。126株副溶血性弧菌,恒温荧光法检测出126株,荧光PCR的方法检测出121株。恒温实时荧光检测仪与荧光PCR仪类似,均可以对检测结果进行实时监测和熔解曲线分析,表明该恒温实时荧光检测仪可广泛应用于基础实验室的科学研究或经济发展相对落后区域的临床初步诊断。

    Abstract:

    In order to detect the Vibrio parahaemolyticus in the import and export foods more accurately and quickly, the study designed the loop-mediated isothermal amplification (LAMP) primer sets targeted the tlh gene of V. parahaemolyticus, and detected the LAMP results real-time by the ESEQuant tube scanner. The results showed that the reaction characterized with high efficiency, high specificity and high sensitivity (1~10 CFU/reaction, about 100 times than the real-time PCR). One hundred and twenty-six out of 126 V. parahaemolyticus strains were detedted as Vibrio parahaemolyticus by the LAMP assay with the ESEQuant tube scanner, while 121 strains were detected as V. parahaemolyticus by the real-time PCR. The ESEQuant tube scanner is comparable to the real-time PCR machine in the sense that both are capable of detecting samples in real-time resulting and both are capable of conducting melting curve analysis, which means the ESEQuant tube scanner system can both served as research application in basic laboratory or offering pre-treatment diagnosis in primary health care settings in developing areas.
