摘要
对重庆市近郊7个区县养鸭场的病死鸭进行了流行病学与临床症状调查、病理剖检和病原分离与鉴定,经对分离获得的3株病原细菌的染色镜检、生化鉴定、动物回归实验,确诊病原为鸭疫里氏杆菌。药敏试验结果显示这3株细菌对庆大霉素、青霉素、链霉素、土霉素等高度敏感,在临床上交替使用这些药物,收到较好治疗效果。将分离菌制成灭活苗免疫1周龄的健康鸭,20日龄时用分离菌进行攻毒,平均保护率达83.3%。
Three strains of Riemerella antatipestifer were isolated from dead ducks in 7 duck-farms in Chongqing.According to the bacterial morphology,biochemical properties and animal inoculation tests,these strains were identified as Riemerella anatipestifer.Antibiotic sensitivity of isolated strains were detected with 9 kinds of antibiotics,and the results showed that these strains were highly sensitive to Penicillinm,Streptomycin,Gentamycin and Terramycine.The clinic control test results also showed these antibiotics could control this disease effevtively.Furthermore.applied the inactivated vaccine,making form the isolated bacteria,the average protective rate was 83.3 ％ in healthy ducks of 1 week old.
