FIELD: veterinary science, microbiology. SUBSTANCE: cultured suspension of at least one pathogen of bacterial infection is subjected for inactivation with aminoethylethyleneimine. Amino- -ethylethyleneimine is added to pathogen culture up to concentration 0.5-4.0% and mixture is incubated for 12-16 h at 37-38 C. After termination of inactivation antigen is precipitated by centrifugation and antigen concentrate is diluted with sucrose-gelatin mixture. Then antigen is combined with oily adjuvant taken in the ratio 1: 1 and for preparing vaccine preparation antigen is used in the amount providing stimulation of active immune response reaction in body of animals and birds after administration of the end preparation. EFFECT: enhanced immunogenic activity and specific safety of preparation, decreased cost of its making. 7 cl, 3 tbl
