Abstract:Hemolysin, heat-stable eterotoxin (ST) and liable- heat enterotoxin (LT) were common pathogenic factors in pathogeinc microbes, such as Vibrio Alginolyticus. In this study, two strains of Vibrio Alginolyticu were screened from several kinds of sea foods and identified by different methods. Both of the two strains could produce LT and ST, one of which showed hemolysin activity. It was inferred that Vibrio alginolyticus from different sources could produce different toxins.
