给有高水平新城疫（ＮＤ）母源抗体的雏鸡，于１日龄时接种４倍剂量ＮＤⅡ系疫苗或于１２日龄时接种规定剂量的相同疫苗，３ｄ后气管内接种致病性大肠杆菌悬浮液，以雏鸡死亡率、细菌检查、ＷＢＣ计数值、嗜异性白细胞比率、ＡＮＡＥ＋细胞比例、淋巴细胞转化率、血清ＮＤＨＩ抗体滴度等为指标，评定了先期接种疫苗与实验性大肠杆菌病的相互影响．结果表明，接种ＮＤⅡ系疫苗对３ｄ后实验感染大肠杆菌病无实质性影响；实验感染大肠杆菌病对先期接种ＮＤ疫苗激发产生主动免疫应答亦无实质性影响．

The 1dayaged and 12daysaged chicks which had high level of ND maternal antibody were inoculated with four times and defined dosage of NDⅡ strain vaccine,respectively. They were intratracheally inoculated with the suspension of pathogenical Escherichia coli at the third day of postvaccination. The morbidity,numbers of WBC,heterophil leucocytes and ANAE+ cells,percentage of transformed lymphoblastic cells and serous ND HI antibody titers were determined in order to evaluate the mutual effects of the prior ND vaccination and artific...
