摘要:
Provided in the present invention is a vaccine composition comprising an immune amount of attenuated live vaccine, inactivated vaccine, subunit vaccine, synthetic vaccine, or genetically engineered vaccine of the porcine pseudorabies virus strain. The vaccine composition can effectively induce antibody generation, and prevent infections of virulent strains of the porcine pseudorabies virus, and provides effective protection for pigs.
摘要:
This invention provides a method of attenuating porcine pseudorabies virus, which can effectively and reproducibly attenuate porcine pseudorabies virus. The attenuated strain of porcine pseudorabies virus by use of said method can provide effective immunization for pigs.
摘要:
The present invention provides an attenuated strain of porcine pseudorabies virus (PRV), in which said attenuated strain of PRV is a variant strain of PRV with inactivation of gI/gE/11K/28K proteins. In addition, the present invention also provides a vaccine composition comprising the attenuated strain of PRV as an antigen, a preparation method and use thereof. Proved by immunogenicity and pathogenicity testing of the live vaccine, said live PRV vaccine can provide a good protection for pigs with no clinical signs observed, indicating excellent immune protection.
