Bovine Herpesvirus 1 (BoHV-1) is a major pathogen of cattle, the infection is accompanied by various clinical manifestations such as infectious bovine rhinotracheitis (IBR), infectious pustular vulvovaginitis, abortion and systemic infection in neonates. Despite of a pronounced immune response the virus is never eliminated from an infected host but establishes life-long latency and may be reactivated. The viral re-excretion is responsible for the maintenance of BoHV-1 within a cattle herd. Vaccines usually prevent the development of clinical signs and markedly reduce the shedding of virus after infection, but do not completely prevent infection. The disease causes significant economic losses and trade restrictions, therefore several eradication campaigns have been carried out or are currently running in different countries. Currently in Europe only a small number of countries have achieved IBR-eradication. In Italy there is no national legislation on IBR, the new trade requirements and the need to limit the introduction of positive animals have led some Italian regions to initiate programs for the eradication, therefore we find regional differences and even provincial.

Abstract
Bovine Herpesvirus 1 (BoHV-1) is a major pathogen of cattle, the infection is accompanied by various clinical manifestations such as infectious bovine rhinotracheitis (IBR), infectious pustular vulvovaginitis, abortion and systemic infection in neonates. Despite of a pronounced immune response the virus is never eliminated from an infected host but establishes life-long latency and may be reactivated. The viral re-excretion is responsible for the maintenance of BoHV-1 within a cattle herd. Vaccines usually prevent the development of clinical signs and markedly reduce the shedding of virus after infection, but do not completely prevent infection. The disease causes significant economic losses and trade restrictions, therefore several eradication campaigns have been carried out or are currently running in different countries. Currently in Europe only a small number of countries have achieved IBR-eradication. In Italy there is no national legislation on IBR, the new trade requirements and the need to limit the introduction of positive animals have led some Italian regions to initiate programs for the eradication, therefore we find regional differences and even provincial.
