What could be causing my golden staph infection?

Staph aureus: This organism was originally named because it produced golden colored colonies on the agar plates on which it was grown. It was subsequently shown that color of colonies was not a species determinant and the production of coagulase was the identifying factor. Without knowing what kind of infection you have it is impossible to know how you got it, but many of us have s. Aureus in our nose & skin.
