| 摘 要： | 副溶血弧菌广泛分布于海水或海产品中,人类摄入或接触污染的水源和食物易引起感染。近年来,有关致病性弧菌引起腹泻的报道逐渐增多,但GB标准的细菌学诊断方法检测周期长达1周左右,而且操作较为复杂,难以满足控制疾病暴发和传播的需要,就这一现状,建立了一套不仅快速、准确,而且操作简便、不依赖昂贵仪器的检测方法,应用于海产品中副溶血弧菌快速检测。采用环介导恒温扩增方法(LAMP),针对副溶血弧菌的gyrB基因设计特异引物,进行恒温扩增。使用该方法最低检出限达到101CFU/mL,灵敏度可以达到0.1pg副溶血弧菌基因组DNA,为海产品中副溶血弧菌的检测提供了一个新的辅助方法。

| Abstract: | Vibrio parahemolyticus is widely distributed in seawater or seafood,human contact with contaminated water or food will be easily caused infection.Recently,reports of diarrhea caused by the pathogenic Vibrio gradually increased.But the GB standard bacteriological diagnostics test cycle up to 1 week or so,and the operation is complex,difficult to meet the need of control of disease outbreaks and spread.Loop-mediated isothermal amplification is a novel nucleic acid amplification method in which reagents react ... |
