摘要:

为了解不同地区鸭疫里氏杆菌病的流行情况,并进一步测定这些地区鸭疫里氏杆菌对常用抗菌药物的敏感性。本试验从广东云浮、广东开平、浙江常山3个地区疑似传染性浆膜炎病鸭中进行了细菌分离,通过鉴别培养、染色镜检、生化试验等对分离菌进行鉴定。采用微量稀释法测定了分离菌株对常用药物的最小抑菌浓度。结果从3个地区共分离鉴定出16株鸭疫里氏杆菌。药敏试验结果表明,3个地区鸭疫里氏杆菌均对头孢类和氟苯尼考高度敏感,对多西环素、大观霉素比较敏感;对恩诺沙星,新霉素等其他受试药物呈不同程度的耐药。本研究为鸭疫里氏杆菌的分离鉴定与药物敏感性测定提供了系统方法,为临床选择合理药物防制鸭传染性浆膜炎提供了理论指导。

Abstract:

In order to understand the prevalence of the duck infectious serositis in different regions,and further to determine the sensitivity of the commonly used drugs for the Riemerella anatipestifer in these area.Bacteria were isolated from suspected infected ducks in Yunfu, and Kaiping in Guangdong province and Changshan in Zhejiang province.The isolated bacteria were identified by differential culture, microscopic examination and biochemical test. Micro dilution method was carried out in drug sensitivity test, and the MIC values of the isolated strains to the commonly used drugs were determined.As a result, a total of 16 strains of Riemerella anatipestifer were isolated and identified from three areas. Data of the MIC showed that all isolates were highly sensitive to cephalosporins and florfenicol;Doxycycline andspectinomycin were sensitive too,but enrofloxacin, neomycin and other tested drugs showed different degrees of resistance.The present study provided a systematic method for the isolation and identification of the Riemerella anatipestifer and for the drug sensitivity test.At the same time, it also provided theoretical guidance for the rational drug control of the duck infectious serositis.

Key words: Riemerella anatipestifer; isolation; identification; drug-sensitivity test; MIC
