FIELD: medicine.
SUBSTANCE: method provides inoculation of bacteria Escherichia coli - strain M-17 on beef-extract broth followed with incubation at t 37°C within 4 days. The 4-day culture Escherichia coli - strain M-17 is heated with flowing steam during 30 minutes. Then the heated culture Escherichia coli - strain M-17 is cooled to temperature 45°C and added to 100 ml of the beef-extract broth. Then the beef-extract broth containing the 4-day culture Escherichia coli - strain M-17 grown at t 37°C in the beef-extract broth is added to 1 litre of the solid agar nutrient medium.
EFFECT: simplified visual count of bacteria Campylobacter jejuni and Campylobacter coli and simplified method for making the nutrient medium.
