In 2005, massive mortality occurred in olive flounder Paralichthys olivaceus farms in Korea, and five isolates were collected from diseased fish. In this study, microbiological and pathogenic characteristics of these isolates were studied. The isolates gave negative results in lysine and ornithine decarboxylase, ortho-nitrophenyl-β-galactoside, and citrate(More)
The organics-degrading bacteria were isolated from sea cucumber (Apostichopus japonicus) outdoor rearing ponds sediment. The bacterial strains were selected according to the isolation growth, pathogenicity, organic degradation rate, and effects on A. japonicus growth and water quality. The screened strains were identified on physiological, biochemical, and(More)
Vibrio scophthalmi, a bacterial pathogen of olive flounder Paralichthys olivaceus, exhibits strain-dependent virulence. No information is available on the comparative pathogenicity of different strains of V. scophthalmi toward olive flounder. In this study, high- and low-virulence strains (HVS and LVS, respectively) were compared in terms of their(More)
