MANNITOL SALT AGAR

Staphylococci are widespread in nature, although they are mainly found on the skin, skin glands and mucous membranes of mammals and birds. The coagulase-positive species i.e Staphylococcus aureus is well documented as a human opportunistic pathogen. Mannitol Salt Agar is a selective medium prepared according to the recommendations of Chapman for the isolation of presumptive pathogenic staphylococci. It is recommended for the isolation of coagulase positive staphylococci from cosmetics, milk, food and other specimens. The USP General Chapter recommends Mannitol Salt Agar as a test medium for isolating Staphylococcus aureus in the Microbiological Examination of Nonsterile Products.
