| 摘 要： | 雏鸡1日龄感染鸡贫血病毒，8日龄接种Lasota疫苗，以未感染免疫雏鸡为对照，于免疫后7、14、28d检测血清免疫球蛋白IgG、IgM、IgA,在凝抑制抗体（HI）滴度；胸腺、法氏囊、脾脏T细胞、IgG^ 、IgM^ 、IgA^ ,抗体生成细胞数量及T、B细胞增殖反应；胸腺、脾脏细胞因子IL－2、IFN活性的变化。结果发现，感染CAV雏鸡Lasota疫苗免疫后，其血清IgG、IgM、IgA免疫球蛋白含量明显减少，HI抗体滴度降低；胸腺、法氏囊、脾脏T细胞、抗体生成细胞数量降低及T、B细胞增殖反应减弱，胸腺、脾脏IL－2及TNF诱生活性降低，表明其细胞免疫和体流免疫功能以及细胞因子免疫调节作用均未感染免疫雏鸡明显减弱。

| Abstract: | Chickens were infected with chicken anemia virus（CAV） at one-day-old and vaccinated with Lasota vaccine 8 days later．Meanwhile，uninfected chickens were vaccinated as controls．At 7、14、28 days post vaccination，the content of IgG、IgM、IgA and HI titer in serum，the number of T cells，IgG＋、IgM＋、IgA＋ antibody producing cells in the thymus、bursa of Fabricius and spleen，the proliferative response of T、B cells，the inductive activity of interleukin 2（IL-2） and interferon （IFN） in the thymus and spleen were tested．It was discovered that the content of IgG、IgM、IgA and HI titer in serum，the number of T cells，IgG＋、IgM＋、IgA＋ antibody producing cells in the thymus，bursa of Fabricius and spleen，the proliferative respanse of T cells and B cells as well as the inductive activity of IL-2 and IFN in the thymus and spleen of infected-vaccinated chickens significantly decreased than those of controls．These indicated that the immune function and immunoregulation were droped post ND vaccination of CAV-infected chickens． |
