摘要
对 3只突然死亡山羊的脏器进行了细菌学检查 ,分离到一种革兰氏阳性大杆菌 ,单在或成双 ,多为短链 ,无荚膜 ,有运动力 ;进行厌氧培养 ,在普通培养基上菌落呈不规则网状 ,分枝从中央向四周延伸 ,边缘不齐 ;血液琼脂平板厌氧培养 48h ,形成边缘不整齐、微隆起、淡灰色、周围有β溶血环的菌落 ;经生化鉴定为腐败梭菌。该菌可致死小白鼠 ,对环丙沙星、阿米卡星等药物敏感。
Internal organs of two sudden death goats were tested by bacteriology.A big rod-shaped Gram-positive bacillus was isolated.These bacilli usually are singe in pairs.Most of them are short-chain ,motile and without capsule.Their colonies or culture-medium under non-oxygen culture are irregular,scattered in all directions from center and without even edges .When they were cultured on blood agar without oxygen for 48 hours,their colonies are fringy,a bit swell and without even edges,surrounded by β-haemolysis.These organisms are identified Clostridium septicum with biochemistry,which can induce the death of mice and are sensitive to some drugs, such as Ciprofloxacin and Amikacin.
