Abstract
Examples are given of observations made with field isolates of suid herpesvirus 1 (SHV-1) which indicate that intergenomic recombination is a common phenomenon associated with the virus. This was further confirmed by experimental co-infection of a pig with 2 virus strains with different, stable and easily identifiable genomic markers, followed by natural transmission to a group of contact pigs. A variety of recombinants was subsequently isolated, while none of the parental strains were re-isolated from any of the pigs. It is suggested that co-invasion of cells and recombination between viral genomes play a role in the life cycle of the virus.Keywords
