FIELD: pharmaceutics.
SUBSTANCE: invention relates to pharmaceutics and microbiology. Method of determining microbiological purity of medicinal agents comprises preparation of a drug sample 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. Then, method includes re-seeding on diagnostic culture media with subsequent biochemical identification of selected microorganisms.
EFFECT: invention reduces amount sample used and minimises loss of sample during analysis.
