Development and Evaluation of a Monoclonal Antibody-Based Blocking Enzyme-Linked Immunosorbent Assay for the Detection of Antibodies against Novel Duck Reovirus in Waterfowl Species.

ABSTRACT: The novel duck reovirus (NDRV) is an emerging pathogen that causes disease in various waterfowl species. Since the outbreak, it has caused huge economic losses to the duck industry in China. A rapid, reliable, and high-throughput method is required for epidemiological investigation and evaluation of vaccine immunogenicity. A good first step would be establishing an enzyme-linked immunosorbent assay (ELISA) that could detect NDRV antibodies in different breeds of ducks and geese from the serum and egg yolk. This study used a recombinant NDRV σB protein and a corresponding horseradish peroxidase (HRP)-labeled monoclonal antibody to develop a blocking ELISA (B-ELISA). The cutoff value of the B-ELISA was 37.01%. A total of 212 serum samples were tested by the B-ELISA, and the virus neutralizat
