Mannitol Salt Agar Plate (Harmonized)

Mannitol Salt Agar Plate is used for the isolation and cultivation of Staphylococci in accordance with microbial limit testing by harmonized methodology of USP/EP/BP/JP/IP.

Koch reported that only Staphylococci grow on agar media containing 7.5% sodium chloride. Chapman studied this phenomenon in detail and concluded that the addition of 7.5% salt to phenol red mannitol agar results in an improved medium for the isolation of plasma coagulating Staphylococci.
