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.
An MSA agar is selective for osmotolerant bacteria meaning for bacteria that can grow in different salt concentrations, and it's differential because it can ferment mannitol.o it doesn't because it doesn't ferment mannitol. P. mirabilis can actually grow on a MAC agar, but it is colorless.
