鸭疫里氏杆菌的分离鉴定及药敏试验

Isolation,Identification and Drug-sensitivity Tests of Riemerella anatipestifer Isolates

为鸭疫里氏杆菌病的防治提供参考,2009年5月,对贵州某肉鸭养殖场送检病鸭进行了剖检病变观察、细菌分离鉴定,并进行了药敏试验。结果表明,分离细菌通过细菌形态、染色特性、生化试验、培养特征鉴定为鸭疫里氏杆菌,7株菌对头孢拉定、头孢曲松钠、头孢噻肟和氟苯尼考高度敏感,对庆大霉素、新霉素、青霉素、多粘菌素B、氟哌酸、复方新诺明、链霉素和卡那霉素耐药。

To make references for prevention and treatment of Riernerella anatipestifer, in May 2009, pathological changes of sick duck was observed, bacteria were isolated and identified and drug-sensitivity tests were carried out in Guizhou meat duck farm. The results showed that the isolated bacteria were identified as Riernerella anatipestifer by bacterium form, biochemistry and cultured characteristics. The seven strains were highly susceptible to cefradine, ceftriaxone sodium, cefotaxime, florfenicol, not susceptible to gentamicin, neomycin, penicillin, polymyxin B, norfloxacin, sinomin comoositea, streDtomvein and kanamycin.
