title: A monoclonal antibody capture enzyme-linked immunosorbent assay for detecting antibodies to infectious bursal disease virus.
abstract: A monoclonal antibody capture enzyme-linked immunosorbent assay (mAb-ELISA) for antibodies to infectious bursal disease virus (IBDV) in chicken sera was developed and compared with conventional ELISA. When sera from farm chickens were tested by the two ELISAs and serum neutralization (SN), the correlation rate between SN and mAb-ELISA was 100% (49/49), and that between SN and conventional ELISA was 81.6% (40/49). In mAb-ELISA, all of the sera that were antibody-negative by SN had low absorbance values (below 0.05), and the absorbance values correlated closely with the SN titers. In the conventional ELISA, however, the sera antibody-negative by SN had various absorbance values ranging from 0.06 to 0.32. mAb-ELISA had much lower non-specific reactions than the conventional ELISA against sera from IBD-negative chickens.
