Molecular cloning was carried out on the Danish strain of bovine viral diarrhea virus(BVDV) to construct strategy for the diagnostic tools and effective vaccine of BVD afterwards. A recombinant DNA clone(No. 29) was established successfully from cDNA for viral RNA tailed with adenine homopolymer at 3'-end. $^{32}P$-labeled DNA probes of 300~1,800bp fragments, originating from the clone 29, directed specific DNA-RNA hybridization results with BVDV RNA. Recombinant DNA of the clone 29 was about 5,200bp representing 41.6% of the full length of Danish strain's RNA, and restriction sites were recognized for EcoR I, Sst I, Hin d III and Pst I restriction enzymes in the DNA fragment.
