Comparative studies with an enzyme-linked immunosorbent assay (elisa) for antibodies to avian infectious bronchitis virus

Abstract

An indirect enzyme-linked irnmunosorbent assay (ELISA) was used to detect IgG class-specific antibodies to avian infectious bronchitis virus (IBV) in chickens. The technique detected specific antibody with a high degree of sensitivity and was more sensitive than neutralisation or haemagglutination-inhibition methods of antibody assay. The possible application of the technique for diagnosis and research on IBV is discussed. © 1981, Taylor & Francis Group, LLC. All rights reserved.
