Vibrio anguillarum is a common bacterial pathogen in fish.However,little is known about its pathogenic mechanism,in part,because the entire genome has not been completely sequenced.We constructed a fosmid library for V.anguillarum containing 960 clones with an average insert size of 37.7 kb and 8.6-fold genome coverage.We characterized the library by end-sequencing 50 randomly selected clones.This generated 93 sequences with a total length of 57 485 bp covering 1.4% of the whole genome.Of these sequences,58... 相似文献

溶藻弧菌的PCR快速检测方法 总被引:4,自引:0,他引:4
为建立溶藻弧菌(Vibrio alginolyticus)的PCR快速检测方法,本研究根据弧菌toxR基因的高变区序列设计1对扩增片段为161 bp的引物,进行了特异性和敏感性试验.结果表明该方法能特异地检测溶藻弧菌,每个PCR反应检测的敏感度为0.01 pg的DNA和3.7CFU的细菌.用溶藻弧菌人工感染大菱鲆,以建立的PCR方法检测感染鱼的肝、脾、肾阳性检出率为100%.该方法可用于对感染溶藻弧菌的水生动物疾病进行诊断. 相似文献
