张家口地区奶牛临床型乳腺炎病原菌的分离鉴定

Isolation and Identification of Bovine Clinical Mastitis Pathogens in Zhang Jia Kuo Region

采集具有临床型乳腺炎奶牛的奶样,经细菌的分离培养、纯培养和生化试验,以确定奶牛临床型乳腺炎的致病菌种类。结果发现患临床型乳腺炎奶牛的致病菌和占分离菌株的百分率为:腐生葡萄球菌19.7%、金黄色葡萄球菌16.5%、兽疫链球菌17.3%、停乳链球菌9.4%、乳房链球菌3.9%、无乳链球菌1.6%、产气肠杆菌17.3%、聚团肠杆菌4.7%、奇异变形杆菌3.0%、大肠杆菌3.0%、蜡样芽胞杆菌3.0%,样品中单纯感染与混合感染的百分率分别为66.0%和27.8%。

Milk was collected from the cows with clinical mastiffs. The kinds of bovine clinical mastiffs pathogens were determined by isolation culture, pure culture and bio-chemical test. The results showed that pathogens and the percentage of isolates of the cows with clinical mastiffs were as follows： S.saprophyticus （19.7%）, S.aureus （16.5%）, S. zooepidemicus （17.3%）, S.dysgalactiae （9.4%）, S.uberis （3.9%）, S.agalactiae （1.6%）, E.aerogenes （17.3%）, E.agglomerates （4.7%）, P.mirabilis （3.0%）, E. coli （3.0%）, B.cereus （3.0%）, percentage of simple infection and co-infection were 66.0% and 27.8% respectively.
