| 中文摘要: |
| 采用倍比稀释法,研究氟苯尼考对哈氏弧菌、副溶血弧菌、溶藻弧菌等8种大黄鱼(Pseudosciaena crocea)致病弧菌的体外抑菌效应;同时以棋盘微量稀释法进行五倍子、黄连、乌梅与氟苯尼考的联合用药试验,并研究了该药对养殖大黄鱼的急性毒性效应。结果表明,氟苯尼考对所选弧菌的最小抑菌浓度(MIC)在0.39～0.78μg/mL,且其MBC值与MIC值相等或为对倍关系;联合用药显示,MIC值比单独使用时略有降低,FIC指数为1.00～0.75,其中以氟苯尼考和五倍子的协同作用最为显著;氟苯尼考口服给药对大黄鱼具有较高安全性,96h LD50>1000mg/kg,对大黄鱼的安全浓度SC>100mg/kg。 |
| 英文摘要: |
| The checkerboard microdilution method was applied to study the effect of florfenicol on inhibiting bacteriain in vitro isolated from diseased Pseudosiaena crocea with disk-diffusion method. It is studied that the effect of florfenicol combined with 3 Chinese herbal medicines and florfenicol with Pseudosciaena crocea. The results showed that MIC values of florfenicol against eight strains of vibrios were in the range 0. 39-0.78 μg/mL，and the minimal bactericidal concentrations( MBC)was equal or doubled to minimal inhibitory concentrations ( MIC). Compared with the single text，the MIC values of combination were slightly lower, and the fractional inhibitory concentration(FIC)index was between 1 and 0.75. The synergic action of Rhus punjabensis Stew and florfenicol were obviously observed; It was found that its LD50(96 h)for Pseudosciaena crocea was higher than 1 000 mg/kg body weight, and the safe concentration of florfenicol was over 100 mg/kg body weight.
