摘要
[目的]为预防控制牦牛口蹄疫病提供参考,对玉树部分县牦牛口蹄疫疫苗免疫状况进行了抗体水平调查。[方法]实验采用O型、Asial型口蹄疫抗体检测液相阻断ELISA法对306头牦牛血清进行O型、Asial型口蹄疫二联疫苗抗体水平检测。[结果]表明:囊谦、称多、杂多、治多四县牦牛口蹄疫O型、Asial型疫苗抗体具有50.00%以上保护力的比例分别为:90%、86.33%。玉树地区口蹄疫免疫状况良好,但各县之间免疫情况存在较大差异,治多、杂多两县口蹄疫抗体水平较低。
[Objective]The aim of this study was to provide references for preventing and controlling yak foot-and-mouth disease. [Method]The immune status of foot-and-mouth disease vaccine in some coun- ties of Yushu was investigated. The O type and Asial type foot-and-mouth disease antibodies detection liq- uid phase blocking ELISA method was used to detect the serum antibody level of type O and type Asial foot-and-mouth disease vaccine of 306 yaks from Nangqian.Chenduo.Zaduo.Zhiduo counties. [Result]The result shown that in Nangqian, Chenduo, Zaduo, Zhiduo counties, the ratio of yak type O and type Asial foot-and-mouth disease vaccine antibodies whose protection over 50.00% was： 90%, 86.33%. [Conclu- sion]Foot-and-mouth disease was in good control in Yushu area, but there were big differences between immunity condition in different counties, and foot-and-mouth disease antibody level was low in Zhiduo and Zaduo.
