POLYCLONAL ANTIBODIES FOR THE IMMUNODIAGNOSTIC OF BOVINE VIRUSES

Authors

Abstract

The objective of the study was to produce polyclonal antibodies to bovine viruses and to test the reactivity in immunoassays such as immunofluorescence, immunoperoxidase and slot blot. Bovine viral diarrhea virus (BVDV), bovine respiratory syncytial virus (BRSV), bovine herpesvirus type 1, 2 and 5 (BoHV-1, BoHV-2 and BoHV-5) blue tongue virus (BTV) and vaccinia virus (VACV) were amplified in cell culture and used to immunize rabbits. Animals were immunized at regular intervals and the hyper immune serum produced was used as primary antibody in the immunoassays. The working dilution for each antiserum was determined by limiting serial dilution and varied from 1: 800 to 1: 51,200. The highest dilutions were observed for immunoperoxidase, when compared with immunofluorescence and slot blot. Dilutions lower than 1:800 were associated with the presence of nonspecific reactions. Anti-BoHV-1, -BoHV-5, -BVDV and -BRSV antisera reacted against heterologous isolates in immunofluorescence and immunoperoxidase assays. It is concluded that the produced polyclonal antibodies have high concentrations of virus-specific antibodies and are an alternative for use in immunoassays.
