PROCESS FOR GROWING PORCINE REPRODUCTIVE AND RESPIRATORY SYNDROME VIRUS AND ITS USE IN VACCINES

摘要

A process for growing a PRRSV in a tissue culture which is susceptible to infection to replicate the virus to an amount sufficient to protect animals against PRRS or be used in diagnosing PRRS or identifying the molecular structure of PRRSV for development of recombinant products, comprising inoculating the virus onto the tissue culture and harvesting the replicated virus.
