Abstract

Recombinant vaccinia viruses expressing the VP7 core protein of South African bluetongue virus serotype 4 (SA-BTV4) were identified by polymerase chain reaction amplification. Expression of VP7 was verified by radio-immunoprecipitation and a F(ab')2-based ELISA. Antibodies to VP7 were detected in sera from sheep that had been infected with 20 different virulent BTV serotypes by using the vaccinia virus (VV) expressed VP7 as antigen in a capture ELISA. F(ab')2-immobilised VV-expressed SA-BTV4 VP7 cross-reacted with sera directed against all 9 African horsesickness virus serotypes and epizootic haemorrhagic disease virus serotype 2.
