    摘要:

    为探索宁夏回族自治区彭阳县肉牛感染布鲁氏菌的风险因素,采用匹配设计的病例对照研究方法,对76个检出肉牛布鲁氏菌感染抗体阳性的养殖场户,按照肉牛养殖场户同在一个行政村,和/或相似养殖规模以及养牛时间差异在±3年内的原则,以1:2比例匹配肉牛布鲁氏菌感染抗体阴性场户,通过问卷形式收集数据,采用条件Logistic回归进行分析。结果显示:通过肉牛经纪人买牛的场户,其肉牛的布鲁氏菌感染风险增大(OR = 5.05,95%CI = 1.50~17.01);养牛场同时养羊且母羊近两年有流产史的场户,所养肉牛感染布鲁氏菌风险增大(OR = 1.86,95%CI = 0.92~3.75)。由此可见,彭阳县肉牛交易方式与当地肉牛布鲁氏菌感染存在密切关联。建议加强牛经纪人管理,提高其布病防控意识,进一步调查当地羊群布鲁氏菌病流行状况。本研究为当地肉牛布鲁氏菌病防控策略制定提供了依据。

    Abstract:

    In order to identify the risk factors for Brucella infection in beef cattle in Pengyang County,Ningxia Hui Autonomous Region,a matched case-control study method was used to collect data from 76 positive farms/households by questionnaires and analyzed by conditional logistic regression. The study was based on the principles that farms/households located in the same administrative village,and/or similar breeding scale and the difference in breeding period was within ± 3 years,and a ratio of 1:2 was used to match negative farms.. The results showed that the risk of Brucella infection in beef cattle increased(OR = 5.05,95%CI = 1.50-17.01)in the farms/households who bought cattle via brokers;so did the farms(OR = 1.86,95%CI = 0.92-3.75)where sheep were also kept and history of abortion in ewes was available in the past two years. It was concluded that the transaction mode of beef cattle was closely related to local infection in the county. Therefore,it was recommended to strengthen the management of cattle brokers,improve their awareness concerning brucellosis prevention and control,and further investigate the prevalence of the disease in local sheep. A basis was thereby provided for future development of control strategies for brucellosis in local beef cattle.
