| 摘 要： | 对某大型奶牛场进行隐性乳房炎的流行病学调查,以及致病菌的分离鉴定,结果得出:对同一牛舍76头泌乳牛进行CMT检测,其中隐性乳房炎的牛发病率为68.42%(52/76),在278个有效乳区中,隐性乳房炎的乳区有109个,乳区阳性率为39.21%(109/278),从10份被检乳汁中共分离出59株细菌,经生化鉴定其主要致病菌为金黄色葡萄球菌、无乳链球菌和大肠杆菌,分别占总数的18.64%。

| Abstract: | The intension of this study is to find out the leading pathogens causing bovine subclinical mastitis, and Isolation and Identification of Pathogenic Bacteria, As the investigation showed: The cow infection rate of subclinical mastitis is 68.42%(52/76). There were 109 breast zone of subclinical mastitis in 278 utility breast zone, the positive infection rate of breast zone is 39.21%(109/278). 59 bacterial strains were isolated from 10 milk samples of subclinical mastitis.The leading pathogens are Staphylococcus aureus, Streptococcus agalactiae and Escherichia coli, which account for 18.64% of total respectively. |
