The 10 double-stranded RNA (dsRNA) genome segments of various isolates of bluetongue virus (BTV) were separated on a polyacrylamide gel, denatured in NaOH, and blotted onto 2-aminophenylthioether paper. Blotted dsRNA segments were detected, using radioactive probes, a cloned copy of DNA 70% fragment of genome segment 7 of BTV-17, whole genome BTV-17 copy DNA, or whole genome BTV-17 dsRNA. These probes detected sequence diversities in different isolates of BTV, and these diversities are discussed in relation to the serotype and the electrophoretic migration patterns of the isolates.
