PROCESS FOR PRODUCING OF VACCINE AGAINST CHICKEN INFECTIOUS BURSAL DISEASE GUMBORO DISEASE SUITABLE OF EARLY PROTECTION

摘要

Vaccine offering early protection for chicken against infectious bursitis, by culturing on eggs of chicken a viral gp coded IBDV2512, optionally IBA25129-8-67, 20/32/00 deposited at NBIMCC under number 3712 or IBDV2512, G-61, 23-OS-96 deposited under number 3713. Vaccine offering early protection for chicken against infectious bursitis, by culturing on eggs of chicken a viral gp coded IBDV2512, optionally IBA25129-8-67, 20/32/00 deposited at NBIMCC under number 3712 or IBDV2512, G-61, 23-OS-96 deposited under number 3713. Following the end of culturing the viral gp., a virus suspension is prepared and mixed with a vaccine having an intermediate-plus degree of virulence and with a gamma radiation treated blood plasma obtained from blood of chickens, immunized previously by an inactivated vaccine. Finally, the vaccine is lyophilized in presence of protective colloids. Eggs or baby chicks are vaccinated.
