  • Type II pseudorabies virus attenuated strain, its preparation method and application
    Patent number: 10240131
    Abstract: The present invention discloses a type II Pseudorabies virus attenuated strain and its preparation method and application. The attenuated strain of pseudorabies virus is gE/TK-double-deficient strain, which is named as PRV-HD/c strain of PRV dual-deletion strain, and the accession number is CGMCC No. 14325. The attenuated strain of the pseudorabies virus of the present invention is obtained from the newly isolated strain of pseudorabies virus type II after deletion of the gE and TK double genes and has reduced pathogenicity and strong immunogenicity and is inactivated by the attenuated strain of pseudorabies virus vaccines or live attenuated vaccines, which can provide effective immunity to PRV susceptible animals such as pigs and mice.
