The present investigation was carried out to compare the antigenic relationship between TRT virus isolates from different countries. The obtained results showed that all virus isolates shared similar physiochemical properties. In virus neutralisation tests marked two way cross reactions between BUT 1 = 8544 (England), STG 761/88 and STG 854/88 (Germany) could be detected. On the other hand VCO 3 isolate (France) showed only partial reaction. Also the SDS-poly acrylamide gel electrophoresis (SDS-PAGE) profiles of three TRT viruses (one from England and two from Germany) were very similar, while the VCO 3 strain from France showed some variation.
本研究旨在比较来自不同国家的TRT病毒分离株之间的抗原关系。所得结果表明，所有病毒分离株具有相似的理化性质。在病毒中和试验中，可检测到BUT 1 = 8544（英国）、STG 761/88和STG 854/88（德国）之间存在明显的双向交叉反应。另一方面，VCO 3分离株（法国）仅显示部分反应。此外，三种TRT病毒（一种来自英国，两种来自德国）的SDS-聚丙烯酰胺凝胶电泳（SDS-PAGE）图谱非常相似，而来自法国的VCO 3株则表现出一些差异。
