[The spectrum of extracellular proteins of staphylococci--the passport of a strain].

The possibility of detecting identical strains was analyzed by comparing extracellular protein spectra of Staphylococcus aureus strains from the collection of the L. A. Tarasevich Institute for Standardization and Control of Medical Preparations. Analysis of the findings confirms that S. aureus and other Staphylococci should be characterized by their protein spectra and this marker should be present in the certificate of the strain in collections. Protein spectrum determination is obligatory for production strains.
