摘要: 为了对引起绵羊肺炎的病原进行分离、鉴定和耐药性分析,本研究通过无菌采集绵羊肺脏并对细菌进行分离纯化、生化试验和PCR鉴定,然后对所得到的溶血性曼氏杆菌分离株进行药物敏感性研究。结果显示,分离纯化得到的细菌为革兰氏阴性短杆菌,具有弱溶血性,经生化试验和PCR鉴定为溶血性曼氏杆菌;耐药性分析显示该菌株对恩诺沙星、庆大霉素、四环素等大部分药物敏感。本研究为绵羊溶血性曼氏杆菌感染的有效防制提供有用的信息和数据。

Abstract: The aim of this study was to isolate the etiological bacteria of sheep pneumoniae and evaluate the antibiotic susceptibility of the isolates. Bacteria was isolated from lungs of sick sheep, and further identified with bio-chemical tests and PCR method, the antibiotic susceptibility of the isolates was determined. The results showed that the isolates were gram negative, organisms with haemolytica. Bio-chemical and PCR method proved that the isolates were Mannheimia haemolytica. The isolates were susceptible to most of the tested antibiotics such as enrofloxacin, gentamicin and tetracycline. The results obtained in this study provided useful information for treatment of Mannheimia haemolytica infection.
