摘    要:从山东荣成养鱼场发病牙鲆分离到一株病原菌M3,革兰氏阴性,杆状,能运动,菌落半透明,用BIOLOG细菌鉴定系统不能鉴定。通过16S rDNA序列分析和同源性检索发现M3菌株与弧菌属的同源性较高,为94%~98%。系统发育学分析表明菌株M3与鳗弧菌关系最近,相似性为996%,其生化性状也和鳗弧菌的特征相似,故可把M3定为鳗弧菌(Vibrio anguillarum)。

关 键 词:牙鲆,  鳗弧菌,  16S  rDNA    系统发育学分析

Abstract:A pathogenic bacterial strain M3 revealed gram negative rod shape, motile and translucent clone was studied. This bacterium was isolated from the skin-ulcer flounder in the fish farm of RongCheng City, Shandong Provice, and could not be identified by BIOLOG ID SYSTEM. Comparative 16S rDNA sequence analyses revealed that strain M3 was most related to the genus of Vibrio. The overall similarity value between strain M3 and Vibrio species were 94% to 98%. Phylogentic analysis showed that M3 strain exhibited the highest level of similarity to Vibrio anguillarum , and the biological features of strain M3 were very similar to that of Vibrio anguillarum. Based on the results obtained, strain M3 was identified as Vibrio anguillarum.
Keywords:Flounder  Vibrio anguillarum  16S rDNA  Phylogenetic analysis
