    ABSTRACT: A dominant bacterium, ZYL-12, isolated from the liver of a diseased orange-spotted grouper Epinephelus coioides, was identified as Vibrio sinaloensis, based on phenotypic and molecular analysis. The median lethal dosage of ZYL-12 was calculated as 1.6 × 105 CFU g–1 fish weight. The infection experiment indicated that ZYL-12 caused noticeable histological lesions to the liver, kidney and spleen of the fish. Growth characteristics showed that ZYL-12 possessed strong environmental adaptability. This note is the first report about the pathogenicity of V. sinaloensis isolated from diseased fish.
