'The serological relationship of herpesvirus ovis to other herpesviruses and its possible involvement in the aetiology of jaagsiekte.

No relationship, however, could be established between herpesvirus ovis and common bovine or equine herpesviruses. Antibodies to herpesvirus ovis were present in roughly 70% of all animals tested and no evidence was obtained for the involvement of the virus in the aetiology of jaagsiekte. On the other hand, the absence of antibodies in sheep sera from Iceland as well as the other data obtained in this study did not exclude involvement of the virus in jaagsiekte.en©1979 ARC - Ondersterpoort and Faculty of Veterinary Science, University of Pretoria (original). ©2016 University of Pretoria Department of Library Services (digital).Veterinary medicineVeterinary medicine -- South AfricaArticle
