Bovine herpesvirus 1 (BHV1) seroprevalence in the breeding cattle population of the Veneto region: prospects for the implementation of a control programme.
The results of a serological survey for bovine herpes virus (BHV1) antibodies in the breeding cattle population of the Veneto region are presented. The data do not support the hypothesis of an high prevalence of BHV1; on farms where vaccination was not carried out most animals were seronegative, and seropositive animals were generally older. Therefore, when drawing up the guidelines for a control programme, systematic immunization (with glycoprotein E-deleted vaccines) should be restricted only to farms with a high prevalence of BHV1 antibodies and/or with a high risk of BHV1 occurrence; in most unvaccinated farms a 'test and removal' policy appears to be more appropriate in order to rapidly eradicate BHV1 from the entire stock.
