Methods for growing pigs and respiratory syndrome virus and their use in vaccines

摘要

The present invention comprises the steps of inoculating PRRSV onto tissue culture and recovering the replicated virus, in an amount sufficient to confirm the molecular structure of the PRRSV to protect the animal from the PRRS, diagnose the PRRS or develop a recombinant product. A method of propagating PRRSV in tissue culture susceptible to infection so that the virus replicates.
