摘　　要：为了调查内蒙古包头市土默特右旗某养牛小区发生的奶牛乳房炎的病原菌种类及其敏感药物,对发病牛乳样进行了病原分离培养、镜检、生化鉴定、药敏试验。试验结果表明,该养牛小区流行的奶牛乳房炎主要是由大肠杆菌、无乳链球菌和金黄色葡萄球菌引起的,3种病原菌对长效土霉素和硫酸链霉素具有一定的耐药性,而对头孢氨苄极度敏感,对新霉素和氨苄西林钠高度敏感。The pathogenetic milk samples from a cattle-raising community in Tumoteyou County of Baotou were selected to perform tests for pathogen isolation and culturing,smear staining,biochemical identification,drug sensitivity to find out which type of mastitis pathogenic bacteria the cows had and which kind of drugs they were sensitive to. The results showed that the prevalence of cow mastitis in the community is caused by Escherichia coli,Streptococcus agalactiae and Staphylococcus aureus. The identified pathogens had certain drug-resistance to long-term soil enzyme and the sulfate chains of enzyme, but they were extremely sensitive to cephalexin and were also highly sensitive to the new enzyme and ampicillin sodium.
