The presence of mannitol and phenol red enables differentiation: pathogenic S. aureus ferments mannitol, producing acid that changes the medium’s color from red to yellow, while non-pathogenic Staphylococcus epidermidis does not.\u003c\/p\u003e\n\n\u003cp\u003eThe CRITERION™ line by Hardy Diagnostics offers exceptional quality, consistency, and ease of use.
