摘　　要：本试验对从内蒙古牧区某地3家奶牛场新引进的457头头胎奶牛临床型乳房炎的76份乳样中共分离到95株病原菌,其中主要为金黄色葡萄球菌30株(31.57%),链球菌14株(14.74%),大肠埃希氏杆菌25株(26.32%)。这其中环境性病原菌占绝大多数,占60.0%。说明此次奶牛临床型乳房炎的爆发很可能是奶牛处于怀孕后期,机体抵抗力下降而乳头被严重污染环境病原菌引发。In this experiment,we isolated and identified 95 strains clinical mastitis pathogens from 76 samples of 457 cows from a dairy farm in Inner Mongolia, there were 30 strains Staphylococcus aureus (31.57%), 14 strains Streptococcus (14.74%) and 25 strains Escherichia coli (26.32%), the environmental pathogens were 60.0%. The results showed that the cow clinical mastitis may be caused by environmental pathogens because of decreased cow immunity in the latter part of pregnancy.
