Diagnostic complementary DNA probes for genome segments 2 and 3 of epizootic hemorrhagic disease virus serotype 1.
Potential diagnostic complementary DNA (cDNA) clones of gene segments 2 and 3 from epizootic hemorrhagic disease virus serotype 1 (EHDV-1) have been produced. Individual segments of EHDV-1 were isolated, denatured with methylmercury hydroxide, and polyadenylated. The polyadenylated RNA was reverse-transcribed and self-hybridized into duplex structures, and the incomplete ends were repaired. The resulting product was then cloned into the plasmid vector pBR322, using the complementary tailing method. Two clones, 1 from segment 2 (E1-2-10) and 1 from segment 3 (E1-3-16) were isolated, colony-purified, and characterized by cDNA/RNA blot hybridization and endonuclease restriction analysis. The cDNA clones of RNA segment 3 of EHDV-1 cross hybridized with the corresponding segment of EHDV serotype 2 by results of cDNA/RNA blot hybridization, but not with RNA of bluetongue virus serotypes isolated in the United States. After cDNA/RNA dot-blot hybridization analysis of 17 EHDV field strains, the segment-2 clone was found to be serotype-specific, whereas the segment-3 clone was serogroup-specific.
