An enrichment medium for the isolation of Staphylococci from grossly contaminated specimens.

• Can detect even low numbers of Staphylococci from samples
• Sodium chloride maintains osmotic equilibrium
• Peptic digest of animal tissue and beef extract provide essential nutrients

The medium is sensitive as it can detect even low numbers of Staphylococci from samples having large proportions of heterogeneous microbial flora. Peptic digest of animal tissue and beef extract provide essential nutrients for bacterial metabolism. Sodium chloride maintains osmotic equilibrium.
