摘　　要：为分析新疆某地区规模化牛场乳房炎病原微生物污染与耐药性情况,在2023年10月—2024年10月跟踪采集了29例奶牛临床型乳房炎病例,并进行病原菌分离鉴定与药敏试验。结果显示,从29份样品中共分离出主致病菌29株,其中,产色葡萄球菌6株、大肠杆菌11株、链球菌12株;药敏结果显示,分离得到的菌株对β-内酰胺类抗生素耐药率较高,对四环素类、酰胺醇类、多肽类、磺胺类抗生素药物敏感率为100%。结果表明,引起该地区规模化牛场临床性乳房炎的主要病原微生物为大肠杆菌和与链球菌,且该药物对四环素类、酰胺醇类、多肽类、磺胺类敏感率较高,该结果可为该场奶牛乳房炎合理治疗提供参考。To analyze the pathogenic microorganisms and drug resistance of mastitis in a scaled cow farm in Xinjiang,we tracked and collected 29 clinical mastitis cases from October 2023 to October 2024 and conducted pathogen identification and drug susceptible tests.The results showed that a total of 29 main pathogenic bacteria were isolated from 29 samples,including 6 strains of Staphylococcus aureus,11 strains of Escherichia coli,and 12 strains of Streptococcus.The drug sensitivity results showed that the resistance rate of the isolated bacteria to beta-lactam antibiotics was high,and the sensitivity rate to tetracycline,aminoglycoside,peptide,and sulfonamide antibiotics was 100%.The results indicated that the main pathogenic microorganisms causing clinical mastitis in the scaled cow farm in Xinjiang were Escherichia coli and Streptococcus,and that these drugs had a high sensitivity rate to tetracycline,aminoglycoside,peptide,and sulfonamide antibiotics.These results can provide reference for the rational treatment of mastitis in the farm.
