Bordetella bronchiseptica is a small, Gram-negative, rod-shaped bacterium of the genus Bordetella. It can cause infectious bronchitis in dogs and other animals, but rarely infects humans. Closely related to B. pertussis—the obligate human pathogen that causes pertussis (whooping cough); B. bronchiseptica can persist in the environment for extended periods.

ActiveCN102302771AEffective therapeuticEffective preventionAntibacterial agentsBacterial antigen ingredientsPasteurella multocida toxinImmune effects
The invention provides a polyvalent inactivity vaccine for preventing and treating atrophic rhinitis of a swine and a preparation method thereof. The polyvalent inactivity vaccine contains inactivated Bordetella bronchiseptica, Pasteurella multocida A, Pasteurella multocida D and PMT (Pasteurella Multocida Toxin) anatoxin. The invention further provides a novel method for culturing and extractingPMT. Compared with the traditional atrophic rhinitis of the swine, the polyvalent inactivity vaccine for the atrophic rhinitis of the swine, provided by the invention, can be used for more generally and effectively treating and preventing the atrophic rhinitis of the swine by comprehensive antigen protection. Finally, in the polyvalent vaccine provided by the invention, the vaccine with a plurality of antigens in a reasonable proportion can be used for solving the problem that the plurality of the antigens interfere each other, thereby improving an immune effect. Furthermore, the inventor provides a water adjuvant by which defects such as incomplete absorption, large side reaction and the like after the traditional alumina gel adjuvant, Freund adjuvant and water-in-oil adjuvant are injected into the water adjuvant can be overcome.

The invention provides a vaccine composition, and the vaccine composition comprises immunization amount of a bordetella bronchiseptica antigen, immunization amount of pasteurella multocida toxoid antigen and an adjuvant acceptable in veterinary medicine. The vaccine composition is capable of effectively controlling co-infected swine atrophic rhinitis caused by bordetella bronchiseptica and pasteurella multocida, and further comprises other antigen compositions for controlling respiratory syndrome caused by secondary infection of swine atrophic rhinitis. By reducing the antigen composition and using pasteurella multocida toxoid to replace pasteurella multocida antigens with different serotypes, the purpose of preventing swine atrophic rhinitis is realized. Also by improving the antigen content in per volume of the vaccine composition, the immunization dosage of the vaccine composition is reduced to 1 / 4 of the dosage of a conventional vaccine without reducing the immunization effect. Therefore, the vaccine composition is relatively low in immunization dosage, relatively less in antigen compositions, relatively low in immunization cost and convenient to use.
