One hundred strains of halophilic vibrios were isolated from 16 species of marine invertebrates of Peter the Great Bay. Based on their morphological and biochemical characteristics, the bacteria were identified as Vibrio parahaemolyticus and Vibrio alginolyticus. Bacterial isolates possessed virulence enzymes (DNAase, lecithinase, catalase) and were characterized by a high enterotoxigenicity. It was determined that 76% of the V. parahaemolyticus strains and 43% of the V. alginolyticus strains were Kanagawa-positive. The isolates showed a high adhesive capability, the average adhesion index was 18.06 cells per erythrocyte for V. parahaemolyticus and 12.55 for V. alginolyticus. The results of this study suggest a high pathogenic potential of the isolated halophilic vibrios, which are an epidemic hazard to marine invertebrates and to humans.
