SUBSTANCE: invention discloses a method for preparing an anthrax diagnostic serum by hyperimmunisation of ox producers with an antigen of the strain Bacillus anthracis M-71. Hyperimmunisation is conducted in increasing doses: first subcutaneous introduction of the antigen 100-120 mln microbial cells together with saponin 2.5-3 mcg; 12-14 days later, the antigen is introduced intracutaneously in a dose of 2.5-3.0 bln microbial cells together with saponin 2.5-3 mcg; 6-7 days later, every 3-4 days, the antigen is introduced intravenously 12-14 times in increasing doses 10.0 to 210 bln. microbial cells. It is followed by blood sampling, keeping at temperature 37-38°C for 2-3 hours, placing in a fridge at 2-8°C for 3-5 days, separating serum. The prepared serum is preserved in 5-7% carbolic acid in isotonic solution in ratio (9-10):1 respectively. The ready serum is sterile and has an AR titre min. 1:1000, a CFT titre min. 1:20. A diagnostic set for anthrax diagnosis comprises the antigen of the strain Bacillus anthracis M-71, the anthrax diagnostic serum and healthy bovine's native serum.
