The invention relates to microbiology, and more particularly to nutrient media used for cultivating bacteria for the subsequent study thereof. A nutrient medium comprising a pancreatic digest of casein, a peptic digest of meat, a heart pancreatic digest, yeast extract, starch and water is characterized in that it additionally contains violuric acid and beef infusion, wherein the ratio of ingredients is (wt %): 0.3-1.0 pancreatic digest of casein; 0.1-1.5 peptic digest of meat; 0.1-0.9 heart pancreatic digest; 0.1-2.0 yeast extract, 0.3-0.8 starch; 0.001-0.05 violuric acid; 2.0-15 beef infusion; the remainder water. The nutrient medium can additionally contain 0.3-2.5 wt % agar-agar and/or 1-20 wt % whole or hemolyzed sheep red blood cells and/or 1-20 wt % whole or hemolyzed human red blood cells and/or 1-15 wt % horse blood serum. This provides for the simultaneous growth of the maximum possible number of bacteria present in an inoculate.
