RECOMMENDATORY RECOMMENDATORY VIRUS FROM TRAIN AND ITS USES

摘要

This invention provides a recombinant herpesvirus of turkeys comprising a herpesvirus of turkeys viral genome which contains a foreign DNA sequence inserted within the EcoR1 #9 fragment of the herpesvirus of turkeys viral genome, and the foreign DNA sequence is capable of being expressed in a host cell infected with the herpesvirus of turkeys. This invention provides a recombinant herpesvirus of turkeys-Marek's disease virus chimera comprising a herpesvirus of turkeys unique long viral genome region and a Marek's disease virus unique short region. Lastly, this invention provides homology vectors for producing a recombinant herpesvirus of turkeys, host cells, and vaccines and methods for immunization.
