安徽省部分地区鸭疫里氏杆菌的分离鉴定及生物学特性研究

Isolation and biological characterization of Riemerella anatipestifer in Anhui province

2007年3月～12月从安徽省不同地区临床疑似鸭疫里氏杆菌感染病/死鸭中分离到26株鸭疫里氏杆菌,通过细菌形态、PCR鉴定、培养特性、生化试验和动物试验,鉴定为鸭疫里氏杆菌。各地区分离株表现为较一致的形态特征和相似的生理生化特性。对不同地区分离到的26株鸭疫里氏杆菌进行了14种常用抗菌药物的药敏试验,结果26株鸭疫里氏杆菌分离株对青霉素G、氨苄青霉素、先锋噻肟、阿莫西林和罗红霉素等几种药物敏感性较高,对庆大霉素和卡那霉素的耐受率最高,对阿米卡星、复方新诺明、链霉素和新霉素等均不同程度地产生了耐药性。本研究为安徽省鸭疫里氏杆菌病的药物防治提供了理论依据。

Twenty six isolates of Riemerella anatipestifer were isolated from the ducks with typical serositis during March 2007 and Decemeber 2007 in Anhui Province. These isolates had identical morphology, similar biochemical characteristics, and strong pathogenicity in animals. Test on 14 antibiotics showed that they were highly sensitive to ten antibiotics such as Ampicillin, Cefotaxime, Tetracycline and Amoxicillin, but less sensitive to some frequently used medicines such as Amikacin, Gentamicin, Kanamycin and Sulfamethoxazole timethoprim.
