祁连山北麓中部地区牦牛常见病的血清学调查

Research on Serological Investigation of Yak in the Central Region of Qilian Mountains

[目的]为了掌握祁连山北麓中部地区牦牛常见病的感染情况。[方法]对祁连山北麓中部地区的牦牛常见病开展了血清学检测。共检测280份血清样品,分别检测了布病、口蹄疫、牛传染性鼻气管炎、弓形虫、牛副结核病的感染抗体。[结果]检出布病阳性样品3份,平均阳性率1.2%;检出口蹄疫病毒非结构蛋白3ABC抗体阳性样品31份,平均阳性率11.1%;检出牛传染性鼻气管炎阳性样品14份,平均阳性率5.0%;检出弓形虫抗体阳性样品87份,平均阳性率31.1%;检出牛副结核抗体阳性样品1份,平均阳性率0.4%。[结论]通过血清学检测,初步掌握了5种疫病的感染情况,为科学防控提供了科学依据。

【Objective】In order to grasp the infection situation of yak common diseases in the central region of the Qilian Mountains.【Method】The serological investigation of yak were detected at the central region of the Qilian Mountains.A total of 280 serum samples were collected.The infection antibodies of brucellosis,foot and mouth disease,infectious bovine rhinotracheitis,Toxoplasma gondii and bovine paratuberculosis were detected,respectively.【Result】The results indicated that there were 3Brucella positive samples,31 FMDV non-structural protein 3ABC antibody-positive samples,14 infectious bovine rhinotracheitis positive samples,87 Toxoplasma antibody positive samples and 1bovine paratuberculosis antibody positive samples in total.The average positive rate was 1.2%,11.1%,5.0%,31.1%,0.4%,respectively.【Conclusion】Through serological testing,the infection situation of five kinds of diseases were mastered,which provide a scientific basis for prevention and control of serological diseases.
