Mitis Salivarius Agar with Tellurite (MSAT) is intended for the selective isolation of Streptococcus mitis, Streptococcus salivarius, and other oral Streptococci and Enterococci found in clinical specimens. MSAT is an enriched selective medium supplemented with Chapman Tellurite Solution for selection and isolation of S. mitis and S. salivarius. Growth of S. mitis on the agar will appear as small or minute blue colonies, while S. salivarius produces blue smooth, gum drop, or rough colonies about 1-5 mm in diameter. Enterococci produce a dark blue or black, shiny, slightly-raised colony on the agar. This media is prepared, stored and dispensed under oxygen-free conditions to prevent the formation of oxidized products prior to use.
