title: Comparative investigation on different turkey rhinotracheitis (TRT) virus isolates from different countries.
abstract: 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.
