[目的]对新疆乌鲁木齐市周边奶驴场泌乳驴进行隐性乳腺炎发病率调查,以及常见致病菌分离鉴定及药物敏感性测试,结果为临床用药提供技术支持。[方法]采集新疆乌鲁木齐市米东区驴场40 头外表健康泌乳驴、头屯河区驴场24 头外表健康泌乳驴乳样。对乳腺炎初筛阳性样品进行常见致病菌分离,并进行药物敏感性试验。[结果]米东区驴场患病率15.00%、头屯河区驴场患病率16.67%。鉴定停乳链球菌2 株、大肠杆菌4 株、无乳链球菌1 株、葡萄球菌1 株、肠杆菌2 株。米东区驴场对阿莫西林药物较敏感,头屯河区驴场对氯霉素药物较敏感。[结论]两个奶驴场奶驴均存在不同程度的隐性乳腺炎发病情况且头屯河区驴场发病率相对高,常见的致病菌为大肠杆菌及链球菌。两个驴场致病菌对抗生素敏感性存在差异,提示应该更加科学的使用抗生素。

[Objective]Investigate the incidence rate of recessive mastitis of lactating donkeys in the milk donkey farms around Urumqi, and isolate and identify common pathogens and test drug sensitivity to provide technical support for clinical medication.[Method]In this study,milk samples were collected from 40 outwardly healthy lactating donkeys in Midong District of Urumqi,Xinjiang and 24 physically healthy lactating donkeys in Toutunhe District of Urumqi,Xinjiang.[Result]The prevalence rate of donkey farms in Midong District was 15.00%,and 16.67% in Toutunhe District.2 strains of S.dysgalactiae,4 strains of Escherichia coli,1 strain of S.agalactiae,1 strain of Staphylococcus and 2 strains of Enterobacter were isolated and identified from the positive samples. The drug sensitivity test showed that Midong donkey farm was more sensitive to amoxicillin and Toutunhe donkey farm was more sensitive to chloramphenicol.[Conclusion]The incidence of subclinical mastitis was high in the two donkey farms. The common pathogenic bacteria were Escherichia coli and Streptococcus. The difference between the two donkey farms suggested that we should use antibiotics more scientifically.
