title: [Serologic and virologic studies of selected cattle with antibodies to bovine herpesviruses].
abstract: In order to investigate the specificity of low titer antibodies to BHV 1, twelve cattle were subjected to stress and dexamethasone treatment. They were monitored virologically by inoculating cell cultures with naso-pharyngeal-, ocular- and vaginal- or preputial swabs and serologically by assessing the prevalence and incidence of antibodies to bovine, caprine-, porcine-, and equine herpesviruses and to bovine leukemia virus. Antibodies were classified as specific for BHV 1 if the animals excreted IBR virus, or if the antibodies neutralized BHV 1 and reacted with BHV 1 antigens, or if they reacted additionally with CapHV antigens. Animals whose sera recognized BHV 1 and BHV 2 but not other herpesviruses, were judged to have experienced both infections. Nine of the twelve animals had specific BHV 1 antibodies. With three animals the question for specificity of their antibodies remains open. Two animals experienced several herpesvirus infections. Therefore, the induction of crossreacting antibodies, directed against epitopes common to herpesviruses, could not be ruled out. The sera of one animal reacted with BHV 1 and BHV 4 antigens in ELISA tests. They did, however, not neutralize BHV 1.
