摘要:
Recombinant subunit vaccines against bovine herpesvirus type 1 (BHV-1) are provided, as well as methods of vaccination and methods of recombinantly producing the subunit antigens or nucleotide sequences employed in the vaccines. Preferably, the subunit is a truncated BHV-1 gIV antigen.
摘要:
A biologically active interferon can be administered to an animal in conjunction with the administration of a vaccine to improve the vaccine efficiency and allow the use of a smaller vaccination dose. This procedure will cause a less severe vaccine infection in the animal than if no interferon was administered.
摘要:
Infectious bovine rhinotracheitis virus (bovine herpesvirus type 1) 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, vaccines for infectious bovine rhinotracheitis containing the same, methods for the production of the same and methods for use of the same. Animals vaccinated with these mutants do not develop antibodies to the viral glycoprotein and can be distinguished serologically from animals infected with infectious bovine rhinotracheitis virus field strains.
摘要:
Bovine herpesvirus type 1 (infectious bovine rhinotracheitis virus) mutants which fail to produce any functional thymidine kinase as a result of a deletion in the thymidine kinase gene. The deletion in the thymidine kinase gene attenuates the viruses so that they can be used as an active agent in a modified live-virus vaccine against infectious bovine rhinotracheitis. This invention also relates to methods for the production and use of the same.
摘要:
Disclosed is a vaccine for non-human animals, which vaccine enables effective immune induction in non-human animals such as livestock or poultry. The vaccine for non-human animals of the present invention comprises liposomes each comprising an antigen molecule(s) bound to the surface thereof, the antigen molecule(s) being derived from a pathogen infectious to the non-human animals. The non-human animals are, for example, livestock or poultry. One most preferred example of the vaccine according to the present invention is an infectious bronchitis virus (IBV) vaccine, which is effective against various isolated IBV strains, and which is expected to be sufficiently applicable even to cases where a mutant strain appeared. Another preferred example of the vaccine according to the present invention is a PRRSV vaccine, which was confirmed to have an effect that reduces fever, lung lesion development, and the like caused by the infection. The present invention enables development of liposome vaccines effective for prevention of infections caused by various non-human animal pathogens including PRRSV as well as IBV.
摘要:
The present invention relates to a hybrid vaccine for protecting a feline against diseases associated with respiratory diseases. The vaccine commonly includes a feline antigen. Methods for protecting felines against diseases associated with feline gastrointestinal and respiratory diseases, including but not limited to feline calicivirus, feline rhinotracheitis and feline panleukopenia, and methods of producing the feline vaccine are also provided.
