Based on Nutrient Broth with an additional 2.5% Sodium Chloride this medium is suitable for use in the investigation of outbreaks involving Staphylococcus aureus especially MRSA. The additional Sodium Chloride inhibits most other organisms allowing the staphylococci to multiply freely even if present in small numbers. The medium is generally used as an enrichment medium in conjunction with subculture onto selective solid media as described in PHE SMI B29 issue No.6.
