摘要
制备了耗牛ETEC铝胶灭活苗、油佐剂苗和蜂胶灭活苗。分别使用 3种佐剂灭活苗进行对比试验。经抗体监测表明在免疫后 7天 ,蜂胶苗产生的抗体效价最高 (2 7) ,随着时间的推移 ,油苗抗体效价最高 (2 9～ 10 ) ,于免疫后 2 9日 ,使用ETEC进行攻毒 ,免疫兔全部保护 ,对照兔全部死亡。证明牦牛ETEC3种佐剂灭活疫苗均能有效保护家兔免受ETEC攻击。
The aluminum_adjuvant inactivated vaccine,oil_adjuvant inactivated vaccine and honey_adjuvant inactivated vaccine were developed and been tested for immune efficiency.The antibody examination showed that the antibody level produced by honey_adjuvant inactivated vaccine was the highest(2 7)at day 7 post immunization.As time pass by,the antibody titre reached its peak with oil_adjuvant inactivated vaccine.They were challenged to all the rabbits with ETECat 29 days post inoculation.The immunized rabbits could absolutely resist the challenge and the rabbits of control group were dead all.The results proved that the all three inactivated vaccines could brought proteciton rabbits from the ETEC of yak.
