摘    要:从患烂尾白浊症的条石鲷肾脏和肝脏等病变组织分离出致病力较强的菌株TP0701,人工感染实验证实该菌株为条石鲷的病原菌。对该细菌进行了形态、生理生化特性测定和16S rRNA分子鉴定,测定16SrRNA基因序列,分析相关细菌相应序列的同源性,构建了系统进化树。结果表明菌株TP0701与恶臭假单胞菌(Pseudomonas putida)的亲缘关系最近,具有98.1%的同源性。结合该菌株的生理生化特性,可鉴定菌株TP0701为恶臭假单胞菌。

关 键 词:条石鲷  16S  rRNA基因  恶臭假单胞菌

Abstract:A pathogenic bacterial strain TP0701 was isolated from red drum(Oplegnathus fasciatus) with tail rot and whitish symptom.It was proved to be the pathogen of the red drum(Oplegnathus fasciatus) by artificial infection test.The traditional physiological and biochemical experiments were done.To investigate the phylogenetic position of this pathogen,16S rDNA of TP0701 was sequenced and compared with that of other related strains.Molecular phylogenetic tree was constructed based on the genetic distance analysis....
Keywords:Oplegnathus fasciatus  16S rRNA gene  Pseudomonas Putida
