Time-suppression test using a colorimetric probe (alamarBlue) that measures bacterial metabolic activity.

ABSTRACT

We developed a time-suppression test using alamarBlue, which will allow estimation of the cidal or static nature of antimicrobials very easily and quickly. As an example, the effects of vancomycin, linezolid, and daptomycin on a representative strain of Staphylococcus aureus were estimated.
