摘  要:
用试管法测定了喹赛多对 4种鱼类常见致病菌的 8个菌株的抑菌活性。结果表明 ,喹赛多对几种供试菌均显示出较强的抑菌活性 ,对柱状嗜纤维菌的最小抑菌浓度 (MIC)为 0 .39μg/ml,嗜水气单胞菌为 0 .78μg /ml,鳗弧菌为 0 .78~ 1.5 6 μg/ml,迟缓爱德华氏菌为 0 .39~ 0 .78μg/ml。喹赛多的抑菌活性较盐酸土霉素、磺胺二甲嘧啶和盐酸金霉素弱 ,而较喹乙醇强。因此 ,以喹赛多替代喹乙醇作为饲料添加药物对于预防鱼类细菌性疾病是适宜的

摘  要:
The antibacterial activity of cyadox against 4 species, 8 strains of pathogenic bacteria to fish was monitored in vitro . The results showed that cyadox has a strong antibacterial activity to the strains. The minimum inhibitory concentration(MIC) of cyadox against Cytophaga columnaris,Vibrio anguillarum, Edwardsiella tarda and Aeromonas hydrophila was 0.39 μg/ml, 0.78 μg/ml, 0.78~1.56 μg/ml and 0.39~0.78 μg/ml,respectively. The results also indicated that the antibacterial activity of cyadox is weaker than that of sulfamidine, aureomycin and oxytetracycline, but stronger than olaquindox. Therefore,it is a possibe for cyadox to replace olaquindox and be added into feeds in order to prevent bacterial diseases infish.
