A selective medium prepared according to the recommendations of Chapman1 for the isolation of presumptive pathogenic staphylococci. Most other bacteria are inhibited by the high salt concentration with the exception of some halophilic marine organisms. Presumptive coagulase-positive staphylococciproduce colonies surrounded by bright yellow zones whilst non- pathogenic staphylococci produce colonies with reddish purple zones.
Mannitol Salt Agar is recommended for the detection and enumeration of coagulase-positive staphylococci in milk, in food and other specimens.
MSA Agar is not intended for Clinical or veterinary use.
