Given what we know, we can confirm that the fact that Mannitol salt agar can determine which species of Staphylococcus is present makes it an example of a selective differential medium.
<h3>What is a selective differential medium?</h3>
This type of medium is very similar to that of a differentialmedium in that it also allows more than one type of microbe to grow.
It also allows the user to continue to distinguish between the microbe colonies based on biochemical differences.
However, in contrast to that of a basic differential medium, this differentialmedium is also selective in that it controls which type of microbe specifically is allowed to grow.
Therefore, we can confirm that since Mannitol salt agar can determine which species of Staphylococcus is present, it can be considered a differential selective medium because it allows multiple microbes to grow while controlling which types are allowed to grow.
