Investigation of possible vaccine-induced epizootics of infectious bovine rhinotracheitis, using restriction endonuclease analysis of viral DNA.

Abstract

Viral DNA was extracted from each of 14 modified-live (ML) bovine herpesvirus 1 vaccines, representing all of the ML infectious bovine rhinotracheitis virus (IBRV) vaccines licensed by the US Department of Agriculture for use in cattle. Restriction endonucleases Pst I and Bgl II were used to establish restriction enzyme patterns for the vaccinal viruses… (More)
