The double-stranded RNA genome from 117 field isolates of bluetongue virus (BTV) serotypes 10, 11, 13, and 17 was blotted onto nitrocellulose paper and hybridized with a radioactively labeled cloned copy of DNA genome segment 2 of BTV-17. Viral RNA from BTV prototype strains 2, 10, 11, 13, and 17 were used as controls. The probe hybridized only with the viral RNA from prototype BTV-17 virus and field isolates of BTV-17. There was no cross hybridization with field isolates of BTV serotypes 10, 11, and 13. A complementary DNA probe developed from genes coding for BTV serotype specificity was effectively used in a slot-blot hybridization system for efficiently characterizing the viral serotype.
