甘南牦牛巴氏杆菌病的流行病学调查

Epidemiological Investigation of Pasteurella Multocida in Gannan Yak

结合近年来牦牛巴氏杆菌病在甘南州流行的实际情况,我们对全州牦牛养殖重点县进行了调查,准确掌握了发病季节、病因和诱发因素。并发现玛曲、碌曲两县的发病明显高于其它县市,平均发病率为4.6%、4.5%。

In combination with the actual epidemic situation of Pasteurella multocida in Gannan in recent years, we investi- gated the key counties of the whole state in yak breeding, and grasped the onset season, etiology and predisposing factors accu- rately. The survey results show that compared with other counties, the incidence of Maqu and Luqu was significantlyhigher, and their rates were respectively 4.6%, 4.5 %.
