Mannitol Salt Agar. Mannitol Salt Agar (MSA) is a selective and differential medium. The high concentration of salt (7.5%) selects for members of the genus Staphylococcus, since they can tolerate high saline levels.Organisms from other genera may grow, but they typically grow very weakly.

Staphylococci have the unique ability of growing on a high salt containing media (2). Isolation of coagulase-positive staphylococci on Phenol Red Mannitol Agar supplemented with 7.5% NaCl was studied by Chapman (3). The resulting Mannitol Salt Agar Base is recommended for the isolation of coagulase-

THE PROCEDURE. Each pair presently has an unknown bacterium. Both of the table's unknown bacteria should fit on 1 agar plate. Pick up one mannitol salt agar plate and divide in half. Inoculate both organisms on the one plate---either a straight line or a zig-zag. Be sure not to get the 2 bacteria too close together.

In case of coagulase positive staphylococci (like Staphylococcus aureus), the mannitol salt agar test results show a change of color to yellow.Coagulase positive bacteria are found to grow as large yellow colonies. In general, coagulase negative staphylococci are found as a part of normal flora in the human body.
