摘要: 快速、准确地确定弧菌种类能够有效防治弧菌病的发生,利用PCR技术对水产养殖动物的弧菌病进行诊断,通常需要采用靶基因作为基础。近年来,常用的细菌诊断靶基因主要有:16S rDNA、16S-23S rDNA基因间区序列、gyrB基因、dnaJ基因等看家基因和某些弧菌特定的毒力基因,如toxR基因、tdh基因、trh基因、vvhA基因、ctxA基因等。

Abstract: Quick and accurate diagnosis of the types of Vibrio can effectively prevent and control the occurrence of Vibrio disease. It is usually needed to use the target genes as the foundation when diagnosing the Vibrio disease of aquatic animals by PCR technology. In recent years, the common target genes for bacterial diagnosis mainly included some house-keeping genes, such as 16S rDNA, 16S-23S intergenic spacer regions, gyrB gene, dnaJ gene and so on, and some specific virulence genes of Vibrio, such as toxR gene, tdh gene, trh gene, vvhA gene, ctxA gene, et al.

Key words: target gene, Vibrio, PCR, rapid detection
