| 摘 要： | 为了解我国部分省（区）规模化牧场中牛副结核病的流行情况,对2015年采集自内蒙古自治区、黑龙江省、湖北省、四川省、安徽省、江苏省6个省（区）规模化牧场的16 172份奶牛血清样品进行了副结核分枝杆菌抗体检测。结果显示,检测样品的副结核分枝杆菌抗体总阳性率为2.59%,6个省（区）的抗体阳性率分别为：内蒙古自治区2.09%、黑龙江省3.90%、湖北省2.05%、四川省5.23%、安徽省8.00%、江苏省1.22%;不同饲养规模牧场的阳性率分别为：大型牧场2.42%、中型牧场2.01%、小型牧场4.32%,小型牧场的阳性率极显著高于中型牧场（P〈0.01）,显著高于大型牧场（P〈0.05）。综上提示,我国安徽省、四川省、黑龙江省等地规模化牧场奶牛的副结核分枝杆菌感染率较高,大型牧场和中型牧场的阳性率低于小型牧场。该次流行病学调查结果可为我国牛副结核病的预防和控制提供参考数据。

Epidemiological Investigation of Bovine Paratuberculosis in Scaled Dairy Farms in Some Provinces of China in 2015 |

| Abstract: | In order to understand the infection status of bovine paratuberculosis in the scaled dairy farms in some provinces of China, a total of 16 172 bovine serum samples from dairy farms in Inner Mongolia Autonomous Region, Heilongjiang Province,Hubei Province, Sichuan Province, Anhui Province and Jiangsu Province were collected in 2015 and used to detect the antibody against Mycobacterium paratuberculosis. The total antibody positive rate of the samples for Mycobacterium paratuberculosis was2.59%, and the positive rate of Inner Mongolia Autonomous Region, Heilongjiang Province, Hubei Province, Sichuan Province,Anhui Province and Jiangsu Province were 2.09%, 3.90%, 2.05%, 5.23%, 8.00% and 1.22%. The antibody positive rate of the dairy farms with different scales was as following： the large scale dairy farms was 2.42%, the moderate scale dairy farms was2.01%, and the small scale dairy farms was 4.32%. The antibody positive rate of the small scale dairy farms was extremely significantly higher than that of the moderate scale dairy farms（P0.01）, and was significantly higher than that of the large scale dairy farms（P 0.05）. It was indicated that the infection rate of Mycobacterium paratuberculosis in the scaled dairy farms in Anhui Province, Sichuan Province and Heilongjiang Province was higher, and the antibody positive rate of the large scale dairy farms was lower than that of the moderate and small scale dairy farms. The results of epidemiological investigation of bovine paratuberculosis obtained in this study offered reference for the control of this disease in China. |
