Abstract：T he aim of this study w as to determine the anti‐bacterial properties of six lactic acid bacterial strains isolated from intestine of fish .The agar diffusion method (Oxford cup method) was performed for assessment of antimicrobial activity against pathogenic bacteria in aquaculture . Comparison of antimicrobial activity against A eromonas veronii by lactic acid bacteria with antibiotic drugs was also tested . Results showed that all selected strains inhibited the growth of A .hydrophila,A .sobria,A .veronii and A . caviae .However , there were no inhibition activities on Vibrio anguillarum , Escherichia coli , Citrobacter f reundii ,A .salmonicida and Yersinia enterocolitica ,and the antibacterial ability of fermentation supernatant was superior to bacteria .The drug susceptibility test revealed that growth of A .hydrophila was inhibited by four kinds of antibiotics ,and that the inhibition abilities of other antibiotics were found to be weakened or disappeared .Based on the results ,it was inferred that the inhibitory effects produced by lactic acid bacteria seemed better than antibiotics ,providing the foundation with development of alternatives to antibiotics .
