Abstract
The present invention provides a poultry vaccine containing a positive marker gene. More specifically, recombinant turkey herpesvirus modified by the presence of an extraneous antigen gene that may be used as a positive marker to identify and track vaccinated animals is provided. When inoculated into host animals, a poultry vaccine comprising the recombinant turkey herpesvirus provided in the present invention can elicit serological immune responses to the marker gene product that may be detected by serological assays such as enzyme-linked immunosorbent assay and serum agglutination test, thus enabling easy identification and tracking of vaccinated animals.
