An isolated polynucleotide molecule, including a DNA sequence, encodes an American PRRS virus, C? Lula huesped, plasimdo, a method and vaccine for generating an American PRRS virus.

摘要

It describes a kind of isolated polynucleotide molecule, including plastics, virus vectors, and transmission host cells including a DNA sequence, which encodes an RNA infection sequence, which in turn encodes an eamerian virus, and a North American PRRS virus encoded in this way. In addition, isolated RNA infection molecules were provided to encode PRRS virus in the United States. It also describes the insulating DNA molecule encoded by the North American prrsnas virus for genetic modification, the infective molecule of RNA, the virus vector and the blood transfusion host cell.And the PRRS virus in the United States was genetically engineered to code this way S. E. also describes the use of tin sacs in vaccines, including these plastics, RNA molecules, virus vectors, and PRRS viruses in the United States, as well as in pigs and other animals. Heptabromodiphenyl ether also absorbs insulated polynucleotide molecules, virus vectors and blood transfusion host cells including a series of nucleosides.He encoded the peptide of an American PRRS virus These viral vectors and the lipids of these DNA transfusions can be used to provide peptides to compensate for mutant peptide coding sequences in DNA sequences that encode genetically modified PRRS viruses in North America to produce functional viruses.
