摘要
本实验应用Lasota苗及其灭活苗联合免疫接种1日龄火鸡,60日龄攻毒。分别在免疫后第7、14、21、35和60日检泪液、气管液、胆汁和肠道冲洗液中IgG、IgM、IgA含量及泪液HI抗体滴度的动态变化。结果表明免疫火鸡上述各项指标明显高于对照,联合免疫组高于Lasota单独免疫组,说明火鸡早期免疫可明显提高呼吸道和消化道相关局部体液的抗体水平和抗感染能力,其中联合免疫优于单独弱毒苗免疫。
An early inoculation of turkey was taken by Lasota alore and Lasota with oil-based ND vaccine at one day old, and those inoculatead turkeys was challerged with NDV at 60 days old, During this time, the dynamic changes of HI titer in tears and IgG、IgM、IgA contents in tears trachea fluid, bile, Intestinal flued in those turkeys was measured at 7、14、21、35and 60-days old. the measured results demonstrated that the HI titer in tear, the contents of IgG、IgM and IgA in tears trachea fluid, bileand intestinal fluid, and the immune proteretion rate after NDV challenge was higher than Controls. The state above suggested that the early inoculation in turkeys can markedly enhance the antibody lael and the ability of cintiinfection in the local body fluiel of relating to respiratory tract and digestive tract, the resuts indicated the inocnlating of Lasota with inactive oil based ND vaccine is betler than the Lasota Vaccine alone.
