藏区牛结核分枝杆菌病流行病学调查与分析

The Investigation and Analysis of Swine Pseudorabies on Epidemiology of Bovine Tuberculosis in Tibetan Area

为了解牛结核病在各藏区牛群中感染和流行情况,于2016~2017年期间分别从甘肃省、青海省、西藏自治区、四川省等4个省藏区随机采集牛血清1252头份,采用ELISA法进行抗体检测。结果显示:四大藏区中只有四川省的藏区血清抗体为阳性,抗体阳性率为4.8%,其他三个藏区的牛血清抗体均为阴性,阳性率为0,四大藏区牛结核病总抗体阳性率达0.8%。统计数据表明四大藏区牛群中结核病的免疫效果很差,提示四大藏区应该注意加强疫苗的免疫接种工作。

In order to understand the infection and prevalence of bovine tuberculosis in Tibetan areas, 1252 samples of bovine serum were collected from 4 provinces in Gansu, Qinghai, Tibet autonomous region and Sichuan Province during 2016-2017 years, and the antibodies were detected by ELISA. The results showed that： only the serum antibody from Tibetan areas in Sichuan province of the four Tibetan areas was positive, and the positive rate of antibody was 4.8%, but bovine serum antibody of the three other Tibetan areas were negative, and the positive rate was 0.The total positive rate of the four Tibetan areal was 0.8% in bovine tuberculosis antibody. Statistics show that the immune effect of tuberculosis in four Tibetan areas was very poor. It is suggested that four Tibetan areas should pay attention to vaccination.
