After the required incubation period, when an even lawn of growth is distinctly visible, the MIC value is read where the pointed end of the inhibition ellipse intersects the side of the strip. Etests can be used as an alternative method to determine the minimum inhibitory concentrations of a wide range of antimicrobial agents against different ...
