| Abstract: | In August 2009, mass mortality of Synechogobius hasta was observed in the shrimp and crabs pond of Ganyu county, Lianyungang city, Jiangsu province. Some pathogenic organisms were isolated from the liver and deep ulceration of the diseased S. hasta. The dominant bacterial strain was Gram-negative, oxidase positive, and fermented glucose to produce acids. In addition, 16S rRNA and gyrB genes analysis showed that isolation was closely related to Vibrio vulnificus than other bacterium. The sequences similarity coefficients were 0.99, on the other hand, and the phylogenetic trees strongly supported isolation were grouped with some reported V. vulnificus. Moreover, the LD50 of the bacteria to S. hasta was 1.63×106 cfu/g. We concluded that V. vulnificus was an important pathogenic bacteria causing canker disease in S. hasta in Ganyu county, Lianyungang city, Jiangsu province. |
