Attenuated recombinant Newcastle disease virus and Newcastle disease vaccine containing the same

摘要

The present invention relates to a recombinant vector for transcription of the Newcastle disease virus (NDV) genome, a strain of attenuated recombinant NDV with a surface antigen of pathogenic NDV prepared by the vector, a method of preparing a recombinant NDV having low pathogenicity and high protectivity efficiency against Newcastle disease (ND) using the vector, and a vaccine against ND containing the recombinant NDV.
