Abstract
Vaccines compositions comprising a pharmaceutically acceptable vehicle and a mutant bovine herpesvirus 1 (BHV-1) wherein (i) at least one non-essential gene of wild-type BHV-1 is deleted and optionally replaced with a gene selected from the group consisting of a foreign gene, a gene encoding a BHV-1 immunogen and a mutant analog of a gene encoding a BHV-1 immunogen; and wherein (ii) the replacement gene is optionally under the control of a promoter; and further wherein (iii) at least one essential gene of wild-type BHV-1 is optionally mutated are provided. Vaccines compositions comprising a pharmaceutically acceptable vehicle and a bovine herpesvirus 1 (BHV-1) wherein at (i) least one non-essential gene is deleted or (ii) an essential gene is mutated are also provided. In addition, related vectors, DNA constructs, a diagnostic assay and methods for treating and preventing BHV-1 infection and other bacterial and viral pathogens of cattle are provided.
