Antimicrobial susceptibility testing can be done using solid or liquid-based medium. Solid-based assays are easy and inexpensive; they are limited by not being as quantitative as liquid-based assays. Agar depth can influence the accuracy of plate-based assays and it is assumed the basis of this effect is antimicrobial agent diffusion. We tested this assumption by using ETEST to quantitate the relationship between agar depth and minimum inhibitory concentration and zone of inhibition.
