丹顶鹤黑鹳等新城疫免疫效果的跟踪研究

Tracking the Immune Effect of Red-crowned Crane and Black Stork against the New Castle Disease

丹顶鹤、黑鹳等属世界珍稀鸟类物种,为我国Ⅰ级保护动物,现已确认鹤、鹳等可以患鸟类的烈性、毁灭性传染病——新城疫。鉴于国内外鹤、鹳新城疫防疫与检测没有系统的研究报道,尚没有一个完整可靠的科学依据来指导防疫程序。本研究采用血凝抑制试验(HI)测定接种新城疫疫苗前后的鹤、鹳,观察其血清抗体效价的消长规律,认定其免疫能力。支持和指导鹤、鹳防疫程序的建立。

Red- crowned crane and black stork, rare and endangered birds listed in Category 1 of national protected birds, were confirmed to be susceptible to the new castle disease, a deadly and devastating infectious disease to birds, yet no systematic research on its immunization in these two birds were reported. In this experiment, hematopexis inhibition （HI） tests was applied, to determine the immune capability, growth and decline of the effect and value of serum antibody against the new castle disease after inoculation of new castle disease vaccine to red - crowned crane and black stork birds, to obtain experimental data for establishment of the defense program.
