| Serum neutralization tests (SN) were performed against classical swine fever virus (CSFV), bovine viral diarrhea virus (BVDV) and border disease virus (BDV) on samples of swine serum collected for screening of antibodies to CSFV, in order to determine the SN value as a differential serological test. Ninety-nine sera out of a sample of 16,664 were positive for antibodies to pestiviruses in an ELISA test which did not distinguish antibodies to different pestiviruses. When submitted to SN, 81 sera were positive for CSFV antibodies only. In 17 sera, crossreactive antibodies to either CSFV, BVDV or BDV were detected. In most of these sera (13 out of 17) the differences between SN titres against the three viruses were not sufficient to estimate which was the... |
