摘要: 采用试剂盒法提取5种致病性弧菌(霍乱弧菌、副溶血性弧菌、创伤弧菌、溶藻弧菌和拟态弧菌)的基因组DNA。分别合成5对特异性引物,对PCR反应体系进行优化后,建立了5种致病性弧菌间的MPCR-DHPLC检测方法。二重PCR-DHPLC检测灵敏度可达到100CFU/ml。建立的MPCR-DHPLC方法在食品中弧菌的检测上具有很好的应用价值。

Abstract: The genome DNAs of five pathogenic Vibrios were extracted by kit method,including Vibrio cholerae,V. parahaemolyticus,V. vulnificus,V. alginolyticus and V. mimicus,and their five pairs of special primers were composed,respectively. The MPCR-DHPLC detection methods among the five vibrios were developed after the PCR reaction systems were optimized. The detection sensitivity of duplex PCR-DHPLC is 100 CFU/ml. The developed MPCR-DHPLC method has good application merit on detecting the Vibrios in foods.
