乳房炎是奶牛业最常见且损失最为严重的疾病之一.为了解天津地区奶牛场乳房炎病原,本研究对天津地区4个奶牛场的77份乳样进行了病原菌的分离与鉴定分析.通过病原分离、细菌形态学观察、生化试验鉴定发现,临床型及亚临床型乳房炎乳样分离菌均以金黄色葡萄球菌和大肠杆菌为优势菌群.药敏试验结果表明,分离菌对环丙沙星、头孢他啶、氧氟沙星、复方新诺明、庆大霉素、卡那霉素、四环素和新霉素敏感,对其他抗菌素药物均呈现不同程度的耐药.本研究明确了天津地区奶牛乳房炎的主要病原,并筛选出了敏感药物,这对该病的防治具有指导意义.

Bovine mastitis is one of the most prevalent diseases in the cow industry with severe economical loss. To understand the etiology of bovine mastitis and provide references for controlling bovine mastitis in Tianjin, in this study, the suspected milk samples of bovine mastitis from four cow farms in this region were analyzed by pathogen isolation, morphology observation, biochemical tests and drug sensitivity tests. The results show that Staphylococcus aureus andE coli. Were the main isolates and they were sensitive to ciprofloxacin, ceftazidime, levofloxacin, cotrimoxazole, gentamicin, kanamycin, tetracycline and neomycin, with various degrees of resistance to other antibiotics. The study demonstrated the main pathogens and sensitive drugs for bovine mastitis in part regions of Tianjin, and provided guiding significance for prevention and control of the disease.
