摘　　要：分别采用药敏片法和试管法研究洋葱对草鱼细菌性烂鳃病病原菌——柱状屈桡杆菌的抑菌和杀菌效果。结果表明:洋葱对该菌有一定的抑菌效果,药物敏感测定表现为抑菌圈的直径为16mm,最小抑菌浓度测定在浓度为5和10(uL/mL)效果显著,低于5(uL/mL)效果不显著;在供试浓度范围内对该菌无杀菌作用。In this paper, the drug sensitivity method and the tube method are adopted to study the onion＇ s antibacterial effect to Fiexibacter Coiumnaris - the pathogen of the bacterial gill rot disease in grass carp. The result indicates that the onion has some antibacterial effect to this pathogen. Through drug sensitivity tests, it shows that the diameter of bactteria inhibiting ring is 16mm; the effect is obvious when the minimal bacteriostatic concentration is 5 or 10（uL/mL）; when the concentration is below 5 （uL/mL）, the effect is not obvious; and the onion＇ s antibacterial activity can＇t work in selective concentration range.
