    摘要:

    2015年7月,上海市奉贤区某奶牛场报告发现25头奶牛结核病阳性病例。为了解疫病来源及风险因素,对该奶牛场开展了现场流行病学调查。结果显示,该场4~6月龄犊牛的结核病流行率为9.41%,6~10月龄发育牛的结核病流行率为6.25%;4个阳性棚舍均接近生活区,其中22号棚舍最接近办公区,暴露在其内的牛确诊为结核的风险最高,是21号棚舍牛的10.67倍(95%CI:3,37.91)。调查认为,该奶牛场结核病传入的主要风险因素是引进动物以及人员流动。根据调查结果,建议将该奶牛场所有结核病检测阳性牛扑杀并进行无害化处理,饲养员定期进行结核病检测,降低人员流动频率,对进出本场的车辆、器具冲洗干净后彻底消毒,防止疫情散播。

    Abstract:

    In July 2015,25 positive cases of tuberculosis(TB)in a dairy farm were reported from Fengxian district of Shanghai city. Then a field epidemiological investigation in this farm was carried out to find the main causes and the possible risk factors. As a result,the prevalence rate of calves between the ages of 4~6 months was 9.41% and that in the 6~10 month-old cows was 6.25%. The 4 positive sheds were all near the?living?quarters. Among them,the nearest shed to office district was shed No.22,in which the cows were most?susceptible,and the risk of infection was 10.67 times higher than shed No.21(95%CI:3,37.91). According to the investigation,introduction of animals and flow of people were the main risk factors associated with occurrence of TB in that farm. Some suggestions for preventing the spread of the disease were proposed,including culling all the TB positive cows and conducting bio-safety disposal for dead animals,regularly detecting TB in cows,reducing the flow frequency of people,and thoroughly washing and disinfecting vehicles and instruments when they were in and out of the farm.
