Technical Examples

The invention provides isolated polynucleotide molecules, including plasmids; viral vectors; and transfected host cells that comprise a DNA sequence encoding an infectious RNA sequence encoding a North American PRRS virus; and also North American PRRS viruses encoded thereby. The invention further provides isolated infectious RNA molecules encoding a North American PRRS virus. The invention also provides isolated polynucleotide molecules, infectious RNA molecules, viral vectors, and transfected host cells encoding genetically-modified North American PRRS viruses; and genetically-modified North American PRRS viruses encoded thereby. The invention also provides vaccines comprising such plasmids, RNA molecules, viral vectors, and North American PRRS viruses, and methods of using these vaccines in swine and in other animals. Also provided are isolated polynucleotide molecules, viral vectors, and transfected host cells that comprise a nucleotide sequence encoding a peptide of a North American PRRS virus. These viral vectors and transfected host cell lines are useful in providing peptides to compensate for mutated peptide coding sequences of DNA sequences encoding genetically-modified North American PRRS viruses so that functional virions can be generated.
