浅谈奶牛结核病检疫净化中存在问题

Problems of Bovine Tuberculosis Quarantine Purification

北京市密云县自2003-2007年,用结核分枝杆菌PPD进行皮内变态反应试验共监测出结核阳性奶牛544头,阳性率1.3%,并对74头结核可疑奶牛进行跟踪调查,其中有25头奶牛淘汰,有49头奶牛,经过复检后有5头检测为阳性,阳性率为10.2%,有44头检测为阴性。因此,做好奶牛的检疫净化工作,扑杀结核阳性牛,净化畜群,着重做好结核疑似奶牛的复检和隔离以及新引进奶牛的检疫、隔离以及消毒工作,是切断传染源防控结核病的重要手段。

We had used tuberculosis mycobacterium PPD to do intradermal allergy test and to monitor a total of 554 cows of bovine tuberculosis were positive,positive rate were 1.3%,72 cows of dubious tuberculosis were investigated,of which 25 out cows,and 49 cows were through review testing with five positive,the positive rate was 10.2%,with 44 testing negative. Therefore,to do the work of purifying cow quarantine,culling TB-positive cattle,purification herd,focusing on doing a good job cows suspected tuberculosis and isolation of the review as well as the newly introduced dairy cattle quarantine,isolation and disinfection work is to cut off the source of infection prevention and control of tuberculosis an important tool.
