摘要
在流行病学调查基础上，采取控制传播媒介和药物预防注射为中心的综合防制措施。在蜱活动的4～11月份，选用双甲脒和螨净，进行牛体表喷洒灭蜱，两种灭蜱药每半月交替使用一次。在牛双芽巴贝斯虫病发病季节5～9月份，选用贝尼尔、咪唑苯脲进行两次预防注射或缓释剂一次预防注射。经过二年防制工作，防制点没有发生牛双芽巴贝斯虫病。牛体蜱数从9～282只／头次下降到0～11．3只／头次。间接血凝试验结果显示，牛阳性率从10％下降到防制后第一年的3．22％和第二年的0；间接荧光抗体试验表明，牛阳性率从23．63％下降到防制后第一年的6．56％和第二年的0。在防制点二头哨牛，经一年的自然放牧，没有发生双芽巴贝斯虫病，血清抗体效价也没有上升，在推广点的应用，也取得良好效果。
On the grounds of epidemiology. we take integreted controls on B. bigemina, including to kill the vector and to inject preventive drugs. Between April to November of tick's active season, we choose Neocidol and Chlorodimeform to spray on the surface of cattle to kill ticks, two drugs were applied at intervals of 15 days by turns. Between May to September of the disease epidemic season, we choose Bevenil and Imizol to inject twice and slowly releasing drug to inject once. After two years of control, the average amount of tick on a cattle decreased from 9-282 to 0-11.3. The IHA test showed that the positive rate from 10% decreased to 3.22% (the first year after control) and 0 (the second year after control); the IFA test indicated that the positive rate from 23.63% decreased to 6.56% (the first year after control)and 0 (the second year after control). Two cattle from the clean area kept in the test plot for a year were not infected with B. bigemina, and the antibody titer of their serum doesn't rise.A good result was gained from other epidemic area after applying this control.
