Abstract:
PURPOSE: Recombinant porcine Aujesky's disease virus provides safe vector vaccine against porcine diseases and can be used to produce effective vaccine against other diseases if antigen of other virus is introduced in it. CONSTITUTION: Recombinant porcine Aujesky's disease virus is useful to prepared a vaccine vector. The vector is constructed by; deletion of K gene; insertion of IL-2 gene; deletion of gI gene; insertion of beta-galactosidase gene as a maker gene; and insertion of foreign gene coding antigen for virus pathogen. Thereby, immunity is improved.
Abstract:
PURPOSE: Provided are a fluorescent vector, which is used for the production of vaccine of porcine Aujesky's disease and a method for selecting recombination virus using the same. CONSTITUTION: A fluorescent vector pHAVE3 is prepared by amplifying pVIII gene corresponding to 5' region of E3 gene of human Adenovirus type II, a partial sequence(27100-28811bp) having 1,712base, before open reading frame of E3 gene being 19kd, a partial sequence(30,851-32,760bp) having 1,910base, after E3-2 polyadenylation signal corresponding to 3' region of E3 gene; cloning them into SpeI of plasmid pGEMT; and inserting BamH I restriction site
