摘　　要：为探讨传染性法氏囊病 (IBD)康复鸡群的免疫变化 ,避免 IBD所引起的免疫干扰 ,本试验对 3 0羽 IBD患鸡在病愈转归期的第 1 0天、第 1 5天、第 2 0天进行血液淋巴细胞转化率及新城疫 HI抗体水平监测 ,其血淋巴细胞转化百分率分别为 (2 2 . 7± 1 . 0 7),(3 4. 6± 2 . 94),(3 6. 2± 2 . 74),新城疫 HI抗体为 2 . 4log2 ,3 . 6log2 ,3 . 9log2。二者与同龄健康鸡相比较 ,其淋巴细胞转化率在感染后 1 0 d存在极显著差异 (P <0 . 0 1 ),至第 1 5天 ,差异依然显著 (P < 0 . 0 5),第 2 0天差异消除。而新城疫 HI抗体水平在整个试验期均明显低于对照组。30 chickens,which had been infected IBDV,have been tested in the rate of transformation of lymphocytes and antibody level of HI of Newcastle disease on the 10th, 15th, and 20th day after cure, The results of these 3 phases were as follow, the percentage of transformation of lymphocytes were (22.7±1.07),(34.6±2.94),(36.2±2.74),the antibody level of HI of Newcastle disease were 2.4 log2,3.6 log2,3.9 log2. With comparison to the normal chickens, these rate of transformation of lymphocytes in experimental chickens were lower in the first 15 day, after the 20th day this difference was eliminated. But antibody of HI of Newcastle disease in experimental chickens was lower than in the normal in whole testing period. 
