Abstract:
PURPOSE: A recombinant Flc-LOM swine fever vaccine virus is provided to easily detect other vaccine virus and outdoor virus and to early detect infected pig. CONSTITUTION: A vaccine virus for swine fever, Flc-LOM virus(KFCC11441P) has a nucleotide sequence of sequence number 1. In the vaccine virus, 52, 96, 220, 405th bases are changed from C, A, G, and G to T, G, T, and A. The vaccine virus Flc-LOM genetic marker or END(Exaltaton of Newcastle Disease virus). A live vaccine for swine fever contains the vaccine virus Flc-LOM virus(KFCC 11441P).
Abstract:
PURPOSE: A vaccine virus for swine fever of gene recombination is provided to easily detect mutation of vaccine virus and to early remove infected pig. CONSTITUTION: A vaccine virus for swine fever, Flc-LOM-BErns virus(KFCC11442P) contains a nucleotide of sequence number 1. An Erns gene of CSFV(classical swine fever virus) is substituted with Erns gene of BVDV(bovine viral disease virus) in the vaccine virus. The vaccine virus is Erns gene marker, Erns serologic marker or END(Exaltaton of Newcastle Disease virus) bio marker. A method for manufacturing swine vaccine virus, Flc-LOM-BErns virus(KFCC11442P) comprises: a step of extracting genomic RNA from swine fever virus strain; a step of synthesizing full-length cDNA to total RNA; a step of removing Erns gene from the synthesized cDNA; and a step of inserting Erns gene of BVDV.
