[Determination of Staphylococcus species-specific antigens by using erythrocyte reagents].

Species-specific (Staphylococcus aureus and S. epidermidis) antigenic and antibody erythrocyte diagnosticums have been prepared. Various tests made with the use of these diagnosticums have demonstrated that the activity of specific antigens is higher in hydrochloric acid extracts than in trichloroacetic and phenolic ones; this activity is linked with undialyzed components and depends on the peculiar features of the strain.
