Restriction endonuclease analysis of canine herpesviruses isolated in Japan.
Eighteen canine herpesvirus (CHV) isolates from Japan and two reference strains were compared by restriction endonuclease analysis technique using total DNA extracts from cells infected with the viruses. In order to select the suitable restriction endonucleases for differentiation of CHV isolates, ten enzymes were used and three of them, HindIII, XbaI, and PvuII, were found to be useful for strain differentiation. With these enzymes, CHV isolates from unrelated individuals were readily differentiated from each other. In contrast, all the isolates derived from the same litter were not distinguishable on the basis of restriction cleavage patterns. However, slight mobility shifts were observed among the isolates from the same litter or the same individual. The results showed that this method provides a powerful tool for epidemiological surveys of CHV infection.
