ABSTRACT:
The present invention relates to pseudorabies virus mutants containing deletion and/or insertion mutations in a major viral glycoprotein gene, such that no antigenic polypeptides encoded by the viral gene are produced. As a result, animals vaccinated with such do not develop antibodies to the viral glycoprotein and can be distinguished from animals infected with pseudorabies virus field strains and known pseudorabies virus vaccine strains. The present invention also relates to vaccines for pseudorabies disease containing the same, methods for production of the same and methods for use of the same.
