evaluation of field isolates of pseudorabies (aujeszky's disease) virus as determined by restriction endonuclease analysis and hybridization. | sixty-seven isolates of pseudorabies virus (prv) from 13 states were cleaved with 4 restriction endonucleases (re), and after electrophoresis in agarose, their banding patterns were photographed and evaluated. the deoxyribonucleic acid (dna) cleavage fragments were designated into regions specified by molecular weight ranges based on lambda phage dna as a size marker. the 67 prv isolates were evaluated according to the total number of cleavage fragments, by the number of fragments within designa ... | 1984 | 6093637 |
