鸡胚气管环纤毛对不同类型AIBV毒株的敏感性

以鸡胚气管环纤毛运动作指示系统，应用鸡胚气管环组织培养不同血清型的７个标准ＡＩＢＶ毒株及５个不同致病型的分离毒株。采用５０ＣＤ５０病毒量ＩＢＶ毒株感染鸡胚气管环培养物，观察感染后不同时间气管环纤毛的存活率。结果表明，鸡胚气管环纤毛对不同血清类型的ＡＩＢＶ毒株敏感性各具特征。

Ciliary Sensitivity of Tracheal Organ Cultures to AIBV Strains of Different Serotypes

Using ciliary activity of chick embryo tracheal organ cultures as a indicator system, the response of tracheal organ cultures (TOC) were examined to seven stardard AIBV strains of different serotypes and five isolated AIBV strains with various pathogenicity. After viruses (containing 50 CD 50 ) were inoculated into tracheal ring organ cultures, the survival rates of cilia were determined. The result showed that the ciliary sensitivities were different among AIBV strains of different serotypes.
