The article is devoted to the development of the development of a differential diagnostic medium for the identification of bacteria of the species Bordetella petrii. The developed selective medium allows the identification of B. petrii bacteria within 48-72 hours. The developed nutrient media are specific in relation to bacteria-associates of other species and genera. The optimal composition of the medium is (per liter): sodium gluconate -20 g, casein hydrolyzate-3 g, yeast extract-1 g, monosubstituted potassium phosphate -1 g, bromothymol blue-0.08 g, bacteriological agar-15 g, cephalexin-0 02 g. The indicator of the medium sensitivity is about 100 microbial cells.
