Abstract

SUMMARY

The DNA of a field isolate and of a vaccine strain of canine adenovirus type 2 (CAV-2) were analysed by digestion with several restriction endonucleases. The I restriction fragments of the field isolate (CAV-2 Glasgow) and the vaccine strain were cloned into the plasmid pBR322. Physical maps of the two viral genomes were constructed by molecular hybridization of I, RI, I, HI and I digests of the viral DNA with the cloned I fragments. The restriction profile of CAV-2 Glasgow was shown to be virtually identical to those of the two prototype CAV-2 strains, Toronto A26/61 and Manhattan. However, the restriction fragment pattern of the vaccine strain of CAV-2 showed characteristic alterations, in particular additional sequences at or near the genome termini.
