摘要: 摘要: 目的 不同品系的鸭对禽流感( AI) 疫苗诱导的效价有差异,分析这种差异是否与主要组织相容性复合体 ( MHC) 有关。方法 用表达 H5 亚型禽流感 HA 基因重组鸭瘟活载体疫苗免疫抗原提呈相关转运体 TAP 基因等 位基因型不同的 4 种 SPF 鸭,比较其血清 HI 动态变化。结果 免疫后连续观察的 9 周中,B3 群 SPF 鸭 HI 抗体效 价始终显著高于另外 3 个群。结论 鸭的不同 MHC 单倍型可能与 AI 疫苗的不同免疫效力相关。

Abstract: Abstract: Objective Different species of ducks respond differently to AIV vaccination. To investigate whether the different response to AIV vaccination is related with different species of ducks with MHC genetic background. Method In this study,four haplotypes determined by TAP gene alleotypes located in MHC loci of SPF ducks were used to compare HI titers changes post vaccination with recombinant live attenuated H5 avian influenza vaccine. Result The result showed that B3 haplotype SPF ducks produced significantly higher HI antibody titers than others during the 9 wks experiment. Conclusion These results hints that duck MHC genetics may affect the immune responses to AIV vaccination.

Key words: AIV vaccination, MHC, SPF duck
