Infectious bursal disease virus (IBDV)%Binary ethylenimine (BEI)%Formaldehyde%Immune response
Infectious bursal disease virus (IBDV) was inactivated by two different chemicals-formaldehyde and binary ethylenimine (BEI). Formaldehyde was used at 0.1% and 0.2%, while BEI was used at concentrations of 0.001 and 0.002 mol/L.These four vaccines were tested for their efficiency in generating humoral immune response in different groups of broiler chicks.Both BEI-inactivated vaccines gave relatively higher antibody titers and were almost twice as efficient as formaldehyde-inactivated ones.
