FIELD: chemistry.
SUBSTANCE: invention relates to biotechnology and can be used for suppressing viability of pathogenic leptospira. The method includes growing strains of bacteria "Bacillus subtilis TNP-3-DEP" and "Bacillus subtilis TNP-5-DEP". The grown strains are used for the preparation of a suspension. The obtained suspension, containing the strains of bacteria "Bacillus subtilis TNP-3-DEP" and "Bacillus subtilis TNP-5-DEP" in equal ratios with the concentration of 5×108 CFU in 1 ml, is introduced into vials with cultures of leptospira, incubated at specified process parameters with the registration of a result by the absence of leptospira in the sample.
EFFECT: invention makes it possible to extend the arsenal of anti-leptospirosis preparations.
