The invention relates to the field of veterinary medicine and biotechnology and the receipt of the associated vaccine to prevent anthrax and nitrobacteria animals. Known vaccine for the prevention of microbacteria cattle containing equal volume ratios formalin inactivated endotoxin and exotoxin derived from local epizootic cultures of the pathogen microbacteria, and adjuvant on the basis of mineral oil and lanolin (Patent RU 1816348, IPC A61K 39/00, 1995). However, the known vaccine is not enough immunogen, as it requires a double injection and provides immunity only against microbacteria for 3.5-4 months. In addition, when receiving vaccines carry out a preliminary selection of local strains for each specific sector, which is not possible in industrial production. Known vaccine against anthrax in animals, containing a suspension of live spores paskapallero, avirulent vaccine strain 55-Vniivvim anthrax (THE 9388-004-00008064-99). Known also inactivated vaccine microbacteria animals containing formalin inactivated endotoxin and exotoxin derived from the production strain "0-1" VIEW pathogen microbacteria, and adjuvant on the basis of mineral oil and lanolin (Patent RU 210519, IPC A61K 39/02, A61K 39/114, 1998). Existing single used independently of each other and do not create immunity in animals against anthrax and nitrobacteria. The use of these vaccines separately requires twice the amount of work and has a strong stress animals. Known associated vaccine against anthrax and nitrobacteria containing an inactivated by formalin-leukocidin-exotoxin that results from the production of strains of Fusobacterium necrophorum "0-1" VIEW, representing a highly purified protein with a molecular mass of 18-20 kDa and adsorbed on aluminium hydroxide, and the suspension of live spores of the anthrax vaccine strain 55-Vniivvim in physiological solution, and adjuvant (Patent RU №2191599, 2002). However, the known associated vaccine does not provide a sufficient immunity against anthrax and nitrobacteria. The objective of the invention is to improve the quality of the target product by obtaining highly immunogenic vaccine capable of forming a long and busy immunity against anthrax and nitrobacteria. The technical result of the invention is achieved in the associated vaccine against anthrax and nitrobacteria containing an inactivated formal is the nom leukocidin-exotoxin, results from the production of strains of Fusobacterium necrophorum "0-1" VIEW, representing a highly purified protein with a molecular mass of 18-20 kDa and adsorbed on aluminium hydroxide, and the suspension of live spores of the anthrax vaccine strain 55-Vniivvim in physiological solution, and adjuvant fact that formalin inactivated leukocidin-exotoxin adsorbed 12-15% aluminum hydroxide in picokelvin buffer with a pH of 8.4 and 8.6, taken at a final concentration of 1.8-2.0%, the suspension of live spores of the anthrax vaccine strain 55-Vniivvim use with the original concentration (5-5,2)×1071 cm3saline and adjuvant contains saponin in the following ratio, wt.%:
Associated vaccine is administered once cattle, sheep, goats, pigs and the reindeers intradermally using a needleless injector in the amount of 0.2 cm3.

Next, the resulting antigen - leukocidin-exotoxin absorb 15% aluminum hydroxide, taken at a final concentration of 2.0%, previously suspended in picokelvin buffer with a pH of 8.6. After adsorption of the antigen on the hydrate of alumina check the neutralization of the residual formalin. To 96,7 g inaktivirovannaja formalin leukocidin-exotoxin with mm 18-20 kDa from strains of Fusobacterium necrophorum "0-1" VIEW a protein content of 6 mg%adsorbed 15% aluminum hydroxide, taken at a final concentration of 2.0%, previously suspended in picokelvin buffer with a pH of 8.6, add 1.2 g of a suspension of live spores of the anthrax vaccine strain 55-Vniivvim with the initial concentration of 5.2×1071 cm3saline solution and 2.1 g of saponin, receiving part 2 in the following ratio, wt.%:
