摘要
通过鸡球虫病多价疫苗(DLV疫苗)临床应用试验,测试此多价疫苗的免疫效果,为解决球虫病的临床预防提供理论支持。试验应用饮水方法免疫1头份鸡球虫DLV型疫苗,免疫8d后用1.5万～2万个混合卵囊感染试验鸡,免疫组的病变分值和血便堆数、死亡率都明显低于非免疫组,说明通过DLV疫苗免疫的鸡对球虫病抵抗力强。
To determin clinical prevention to chicken coccidiosis, we detected the immune effect of chicken coccidiosis multivalent vaccine（DLV vaccine） by a test. The test chickens were infected with 15, 000 to 20,000 admixing egg balls, 8 days after immuning one portion DLV vaccine by a drinking way. The value of pathological changes , number of bloody stools, and death rate of immuning group were obviously lower than nonimmuning group. It showed that the chickens injected with DLV vaccine got strong resistance to coccidiosis.
