摘  要:
为了验证抗菌药物对奶牛结核病PPD试验结果的影响,对PPD实验阳性牛,用一定剂量的链霉素并加以地塞米松进行刺激,结果发现:犊牛(≤1岁),转阴率为35.3%,88.2%的牛皮差减小;青年牛(≤2岁),76.7%的牛皮差减小;成年母牛(≥2岁),42%的牛皮差减小。这说明使用一定剂量和疗程的抗菌药并加以激素,能够明显影响PPD试验的结果。因此在检疫前要避免使用此类药物。

摘  要:
For the purpose of validating the effects of antibacterial drugs on PPD test results of cow tuberculosis(TB),cows tested positive by PPT experiment were treated with a dose of Streptomycin and Dexamethasone. According to obtained results,the negative conversion rate of calves(≤ 1 year old)was 35.3%,and the cowhide difference decreased in 88.2% of the calves. For the youth(≤ 2 years old),76.7% of them were observed a decrease of cowhide difference,while the ratio in adult cows(≥ 2 years old)was 42%. This study indicated that the results of PPD test could be significantly effected by the usage of combination of the hormone and antibacterial drugs of certain dose and duration. Therefore the use of such drugs should be avoided before conducting TB quarantine.
