    • The disclosed invention is directed to (1) recombinant bovine herpesvirus genes having foreign genes inserted therein, (2) infectious recombinant bovine herpesviruses carrying these recombinant genes, (3) methods of producing these recombinant bovine herpesviruses, (4) methods of immunizing animals against diseases caused by bovine herpesviruses using these recombinant bovine herpesviruses as vaccines, and (5) methods of detecting infection of an animal by these recombinant bovine herpesviruses. In its preferred form, the invention is directed to the construction of an infectious recombinant bovine herpesvirus type 1 having a functional &bgr;-galactosidase gene inserted in and thereby inactivating the thymidine kinase gene (e.g., Gal-TK); infection of an animal with the resultant avirulent vaccine virus is detected by assaying the animal's respiratory secretions for the presence of virus having &bgr;-galactosidase activity in host cells.
    • 所公开的发明涉及(1)在其中插入有外源基因的重组牛疱疹病毒基因,(2)携带这些重组基因的感染性重组牛疱疹病毒,(3)产生这些重组牛疱疹病毒的方法,(4) 使用这些重组牛疱疹病毒作为疫苗的牛疱疹病毒引起的疾病,以及(5)通过这些重组牛疱疹病毒检测动物感染的方法。 在其优选形式中,本发明涉及一种具有插入功能性β-半乳糖苷酶基因并由此使胸苷激酶基因(例如Gal-TK)失活的感染性重组牛疱疹病毒1型的构建; 通过测定动物的呼吸道分泌物以检测宿主细胞中具有β-半乳糖苷酶活性的病毒的存在来检测具有所得无毒力疫苗病毒的动物的感染。
