    Abstract:
    An indirect double antibody sandwich enzyme-linked immunosorbent assay (ELISA) was developed for the detection and titration of serum antibodies to bovine respiratory syncytial virus (BRSV). The ELISA was compared with a complement fixation (CF) test and a test for virus neutralising antibody in serum (virus neutralisation [VN] test). Testing sera collected in dairy herds revealed the closest correlation between the results of the ELISA and the CF test with respect to BRSV antibody titres. The VN test detected BRSV antibodies in a higher percentage of acute phase sera compared to the other two tests in field samples and in early bleedings of experimentally infected calves. However, the VN test was less effective in making a diagnosis of BRSV infections on the basis of a significant titre increase in paired sera. For this purpose the ELISA was found to be the most sensitive test.
