porcine reproductive and respiratory syndrome vaccine virus |
| abstract |
The present invention relates to improved live porcine reproductive and respiratory syndrome virus. Genetic analysis and selection for improvement of viruses through repeated passages in tissue culture based on phylogenetic grouping. Assess the ability of modified live viruses to confer protective immunity against heterologous viruses. Modified live viruses can be used in vaccines, especially in vaccines that can treat pigs infected with multiple heterologous viruses. |
