摘要
探讨了鸡传染性法氏囊病 (IBD)活疫苗对鸡新城疫活苗免疫的影响。将四种IBD活苗分别接种 30日龄SPF公雏 ,4天后再免疫鸡新城疫LaSota系活疫苗 ,同时检查法氏囊损伤情况。试验结果表明 ,所选IBD活疫苗对雏鸡法氏囊均有不同程度地损伤 ,并且诱导产生ND_HI抗体的时间被推迟。
Immunosuppressive Effects of live IBD vaccines on live ND La Sota vaccine in chickens was determined.30 day_age specific pathogen free(SPF)chickens were inoculated with 4 variant virulent live IBD vaccines,prior to immunization with live ND La Sota vaccine for 4 days.The results showed that all the live IBD vaccines would cause bursal Fabricuis of chickens to damage to a degree.And humoral immune response against ND vaccine in chickens was suppressed dramatically.
