摘要: 对江西省某养鸭场送检的病死鸭进行病理剖检、细菌分离,经生化鉴定确定病原为多杀性巴氏杆菌。该分离菌株对头孢氨苄、头孢曲松、头孢唑啉、甲氧嘧啶、复方新诺明和氯霉素高度敏感;对大观霉素、卡那霉素等中度敏感;对头孢噻肟、四环素、林可霉素和诺氟沙星低度敏感;对阿莫西林、青霉素、氨苄西林和头孢吡肟不敏感。将分离菌株人工感染鸡、鸭、兔和小白鼠,感染后24 h内死亡率为100%,死亡动物均分离到与原分离菌株形态特征、培养特性一致的细菌,结果表明该分离菌株为多杀性巴氏杆菌强毒株。

Abstract: A virulent strain of Pasterrella multocida was isolated and identified from ducks in Jiangxi province. The isolate was highly sensitive to cephalexin, cefatriaxone, cefazolin, sulfamethoxydiazine, SMZ-TMP and chloromycetin,medium sensitive to spectinomycin and kanamycin,lowly sensitive to cefotaxime, tetracycline,lincomycin and norfloxacin while insensitive to amoxicillin, penicillin, ampicillin and cefepime. The mortalities rates of chickens, ducks, mice and rabbits infected with the isolate within 24 h were 100%. The result indicated that the isolate was a virulent Pasteurella multocida.

Key words: Pasterrella multocida; isolation and identification; ducks; virulent strain
