FIELD: pharmaceutics.
SUBSTANCE: invention relates to pharmaceutics and microbiology. Method of determining microbiological purity of pharmaceutical substance comprises preparation of a sample of a pharmaceutical substance by diluting in tryptic soy broth or medium No. 8. Method includes seeding a sample on a liquid accumulation selective medium with subsequent incubation thereon. Method includes re-seeding on diagnostic nutrient media with subsequent biochemical identification of selected microorganisms.
EFFECT: invention increases accuracy of determining microbiological purity and reduces duration of analysis of pharmaceutical substances of biotechnological origin on "Microbiological purity" and amount of used sample.
