Abstract:
PURPOSE: A live vaccine containing a recombinant chimeric pestivirus for preventing swine fever is provided to easily trace virus for the live vaccine. CONSTITUTION: A live vaccine for preventing swine fever contains chimeric pestivirus KD26_E2LOM of sequence number 2 which is recombined to discriminate vaccine virus and outdoor-infectious virus. A gene marker is expressed by substituting E2 gene of pACBVD26 of sequence number 1 with a swine fever E2 gene. A serological marker is a marker for E^rns specific antibody.

Abstract:
A viral vaccine containing isolated virus strains is provided to improve use safety and immunogenicity by using inactivated viruses, and increase production yield of cows, so that the vaccine is useful for prevention of abortion or stillbirth in cows caused by viruses via mediation of Culicoides spp. A viral vaccine for prevention of abortion or stillbirth in cows contains cultured medium of inactivated virus strains of akabane virus(K-9)(KCTC 18117P), chuzan virus(KSA9910)(KCTC 18118P) and aino virus(YoungAM)(KCTC 18119P), and is produced by: inactivating akabane virus(K-9)(KCTC 18117P), chuzan virus(KSA9910)(KCTC 18118P) and aino virus(YoungAM)(KCTC 18119P) by adding 0.1M BEI(binary ethylene imine) prepared by solubilizing 2-BEA(2-bromoethylamine) in 0.2N NaOH, and treating the solution in a constant temperature water bath of 37 deg. C for 1 hour to them; mixing the 3 kinds of viruses in a weight ratio of 1:1:1; and adding 40-60 wt.% of IMS 1314 as an immunomodulator into the viral mixture.
Abstract:
Recombinant proteins of enzootic bovine leukemia virus are provided to improve specificity and sensitivity of detection as compared with conventional antigens by expressing the envelope glycoproteins in baculovirus and secreting the envelope glycoproteins to insect cells. A method for producing a recombinant protein of enzootic bovine leukemia virus expressed in an insect cell comprises the steps of: (1) cloning an envelop glycoprotein of enzootic bovine leukemia virus from the blood of enzootic bovine leukemia positive cows to baculovirus and sequencing the cloned protein; (2) transforming an insect cell with a recombinant virus gene of SEQ ID NO:1 to express a recombinant protein of SEQ ID NO:2; and (3) purifying and concentrating the recombinant protein produced from the insect cell, wherein the recombinant virus gene of SEQ ID NO:1 is prepared by recombination of envelop glycoprotein genes including a whole gp51 gene and a part of gp30 gene.
