摘要
在经IBD弱毒苗免疫和未免疫的30~59日龄AA鸡研究了感染IBDV后红细胞免疫功能的变化。结果表明:从以IBDV攻毒前1天到攻毒后头5天内,未免疫攻毒鸡(A组)和免疫攻毒鸡(B组)RBC-CR1花环率降低或显著降低,而未免疫未攻毒鸡(C组)没有类似变化,高于B组,明显高于A组,以后A和B组逐渐回升到攻毒前水平。A和B组RBC-IC花环率在IBDV攻毒后第5天明显降低,均显著低于C组水平,以后A组仍处于较低水平上变动,B组即逐渐回升,三组比较,A组仍低于C组,同时也低于B组。
Changes of RBC immune function in immunized with attenuated IBDV and nonimmunized Arbor Acres(AA) chickens of 30 59 day of age,infected with virulent IBDV were studied The results showed that RBC CR 1 rosette rates in non immunized infection chickens(A group) and immunized infection chickens(B group) decreased or did obviously,however,those of non immunized uninfection chickens(C group)did not decreased,but surpassed those of B group and were higher significantly than those of A group from day 1 before to the first 5 days after infection of IBDV,and then the rosette rates of A and B groups increased gradually to pre infection level RBC IC rosette rates in A and B groups dropped significantly on the 5th day after infection of IBDV,and were obviously lower than those in C group,followed by keeping a relatively low level and B group rising gradually,and A group was much lower than those of B and C groups
