摘要
2017年5月,在北京市密云区某奶牛场送检样品中,通过结核分枝杆菌γ-干扰素试验检出51份阳性,样品阳性率高达29.5%(51/173)。为找出发病原因,及时有效控制疫病,通过临场皮试、询问场主、查看现场及相关风险因素识别等方法,进行了流行病学调查,结果确诊36份,并对阳性牛及时进行了扑杀。经风险因素分析,推断可能的感染因素为饲喂从疫区购入的饲草。本调查提示,奶牛养殖户应注意饲草来源及质量,进一步加强饲养管理,识别和控制相关风险因素,做好相关检疫检测工作,以达到有效净化奶牛结核病的目的。
In May 2017,51 positive samples submitted by a dairy farm in Miyun District of Beijing City were confirmed by γ-interferon assay of Mycobacterium tuberculosis,and the positive rate reached up to 29.5%(51/173). In order to find the cause and control the disease timely and effectively,an epidemiological investigation was carried out through on-spot skin test,consulting the owner,surveying the scene and identifying related risk factors,and then 36 positive cattle were confirmed and culled in time. Based on analysis of risk factors,it was inferred that the infection may be caused by the forage purchased from infected area. Therefore,the farmers should pay attention to the source and quality of forage,further strengthen management of feeding,identify and control related risk factors,and carry out relevant quarantine and detection work,so as to eradicate cow tuberculosis effectively.
