摘要:
The present invention relates to a gD-negative Bovine Herpesvirus mutant, that has the property of direct cell-to-cell transmission. The invention also relates to a DNA-fragment capable of conferring this property to Bovine Herpesviruses, not possessing the direct cell-to-cell transmission capability. Also, the invention relates to a vaccine based on this mutant, and a method for the protection of animals against Bovine Herpesvirus.
摘要:
The present invention is concerned with a Bovine Herpesvirus I (BHV-I) mutant comprising a heterologous gene introduced into a section of the BHV-I genome. The invention also relates to a vector vaccine comprising such a BHV-I mutant which expresses a heterologous polypeptide derived from a bovine pathogen and induces an adequate immune response in an inoculated host against both FHV an the bovine pathogen. Furthermore, the invention relates to a method for obtaining a BHV-I mutant by self-selection.
摘要:
The invention relates to a method of preparing live attenuated vaccines containing an oil-in-water (o/w) emulsion, and to live attenuated vaccines so obtained. The method is particularly suitable for preparing a live attenuated Aujesky vaccin. The live attenuated vaccines according to the invention can also be prepared by dissolving the live virus component into an activated vaccine containing one or more antigens formulated as an o/w-emulsion.
摘要:
Described are thymidine kinase negative temperature resistant mutants of bovine herpesvirus effective in inducing resistance to infectious bovine rhinotracheitis, methods for their production, methods for maintaining them in viable form, and methods for administering them to animals in immunologically effective doses to induce reistance to infectious bovine rhinotracheitis.
