| Abstract: | A blocking enzyme-linked immunosorbent assay (ELISA) was developed for detecting antibodies against bovine enterovirus (BEV) in bovine sera. In this ELISA, bovine serum samples were allowed to react with captured viral antigens (by specific chicken IgG), before the addition of specific mouse IgG for measuring non-occupied viral epitopes. The ELISA was slightly more sensitive and required a shorter time period than traditional serum neutralisation (SN). Among the 871 bovine serum samples tested so far, the titres produced by this assay had a significant correlation with those recorded by SN. The ELISA could be used as an alternative assay for SN in a large-scale BEV antibody investigation. |
