奶牛乳房炎病原分离鉴定与分析

On the Isolation and Identification of Bacteria for Dairy Cow Mastitis

本试验对吉林地区两家大型乳业集团奶牛乳房炎病牛乳样进行分离鉴定,8份乳样共分离到62株菌,其中含51株4种主要病原菌。4种病原菌不同临床型的比例是:金黄色葡萄球菌占36.36%、大肠杆菌占9.09%、无乳链球菌占27.27%、乳房链球菌占9.09%;隐性型中金黄葡萄球菌占38.89%、大肠杆菌占27.28%、无乳链球菌占11.11%、乳房链球菌占11.11%。

The experiment isolated and identified bacteria from cow milk samples from two milk industry group in Jilin suburb.Isolated 62 bacterial strains from 8 samples,in which 51 bacterial strains contains 4 main pathogenic bacteria.The four bacterial rate of clinical mastitis is that Staphylococcus Aureus is 36.36%,Escherichia coli is 9. 09%,Streptococcus agalactiaes is 27.27%,Streptococcus uberis is 9.09%.And the four bacterial rate of recessive type is that Staphylococcus Aureus is 38.89%,Escherichia coli is 27.28%,Streptococcus agalactiaes is 11.11%, Streptococcus uberis is 11.11%.
