چکیده انگلیسی
Vibrio vulnificus infections have resulted in great economic losses in intensive aquaculture in China. However, very little was reported on the characterization of pathogenic V. vulnificus strains from freshwater fishes. In this study, a Gram-negative bacterium was isolated from the diseased grass carp (Ctenopharyngodon idellus) and tentatively named strain GCV-515, which was then identified as V. vulnificus by the biochemical characteristics and 16S rDNA, gyrB, CPS and OMP genes sequencing analyses. The pathogenicity of V. vulnificus to grass carp was determined by challenge experiments, and the LD50 of GCV-515 with intraperitoneal injection was 7.53Ã103 CFU/g fish weight. Histopathology examination indicated the inflammatory cellular infiltration in submucosa of intestine, venous congestion in liver and necrosis of epithelial cells in the secondary lamella. To our knowledge, this is the first report on the V. vulnificus isolated from the diseased grass carp.
