摘　　要：选取鸭疫里默氏杆菌的一株地方分离株GN52,按照生长的最适条件,在马丁固体培养基上连续传代。分别选取第3代、第11代、第21代、第31代、第41代、第51代和第61代的细菌,对其进行染色镜检、生化试验、药敏试验及动物实验。结果表明,随着代次的增加,该菌株染色形态、生化特性及抗药性均未发生明显变化,但毒力有逐渐下降的趋势。The isolate GN52 of Riemerrella anatipestifer was passaged on the Martin Medium successively according to the optimum condition. The experiments included Gram staining, biochemical test, drug sensitivity test and animal experiments were carried out on the bacteria of 3rd, 11th, 21st, 31st, 41st, 51st and 61st generations. It indicated that the bacterial morphs, biochemical character, drug resistance of the strain had no obvious change, but the virulence showed a trend of reduction.
