Infectious Bronchitis Virus (IBV)

Infectious bronchitis virus (IBV) is a highly contagious viral disease of chickens that is usually manifested as a respiratory condition. An assessment of immune status, as well as serological identification of IBV, requires a measurement of antibody to IBV in serum. Enzyme-linked immunosorbent assay (ELISA) systems have proven efficacious in the quantification of antibody levels to IBV, and facilitate the monitoring of immune status in large flocks.
