摘　　要：对采集的43份乳样进行病原菌的分离培养、鉴定和耐药性分析。结果表明,乳样中共分离出6种61株病原菌,其中大肠杆菌21株,占34.4%;金黄色葡萄球菌17株,占27.9%;凝固酶阴性葡萄球菌11株,占18.0%;无乳链球菌7株,占11.5%;乳房链球菌3株,占4.9%;绿脓杆菌2株,占3.3%;表明该地区主要病原菌依次为大肠杆菌、金黄色葡萄球菌、凝固酶阴性葡萄球菌。药敏试验显示,主要病原菌菌株对青霉素、氨苄西林、链霉素、红霉素、万古霉素具有重度或中度耐药,对头孢唑啉、阿米卡星、头孢曲松、庆大霉素、环丙沙星等敏感。In order to understand the main pathogenic bacteria and drug resistance of clinical mastitis in the dairy goat breeding area of Fuping County,Weinan City.And provide a basis for the prevention and treatment of this disease in the local area,43 milk samples were collected for pathogen isolation,cultivation,identification,and drug resistance analysis.The results showed that a total of 61 strains of 6 pathogenic bacteria were isolated from the milk sample,including 21 strains of Escherichia coli,accounting for 34.4%;17 strains of Staphylococcus aureus,accounting for 27.9%;11 strains of coagulase negative Staphylococcus,accounting for 18.0%;7 strains of Streptococcus agalactiae,accounting for 11.5%;3 strains of Streptococcus pyogenes,accounting for 4.9%;Two strains of Pseudomonas aeruginosa,accounting for 3.3%;This indicates that the main pathogenic bacteria in the region are Escherichia coli,Staphylococcus aureus,and coagulase negative Staphylococcus.The drug sensitivity test showed that the main pathogenic bacterial strains have severe or moderate resistance to penicillin,ampicillin,streptomycin,erythromycin,vancomycin,and are sensitive to cefazolin,amikacin,ceftriaxone,gentamicin,ciprofloxacin,etc.
