Description

M.S. Broth is a selective medium used for the selective isolation and enrichment of Staphylococcus pathogenic spp. from pharmaceuticals products. It is formulated according to Chapman formula.

The high sodium chloride content present in the medium inhibits the growth of other microorganisms, allowing the development of Staphylococci only; the presence of mannitol with a pH indicator (phenol red) makes possible to differentiate between staphylococci, pathogens that ferment mannitol from non-pathogenic ones that do not ferment mannitol.

Among the Staphylococci, the only strain fermenting mannitol with acid production is Staphylococcus aureus, whose colonies have a yellow-gold coloration. The name of this species comes from the typical yellow-gold color of the colonies, surrounded by a yellow halo.
