The Minimal Inhibitory Concentration (MIC) and the Nathan's Agar Well Diffusion (NAWD) tests are bacterial antimicrobial susceptibility predictors. Some suggest that the NAWD is not as reliable as the MIC test. We compared the MIC and NAWD tests as to how well they agreed to bacterial sensitivity or resistance and predicted clinical outcome of burn wound infections. Using 65 bacterial isolates from burned patients, the MIC and NAWD tests agreed in 60.0% of the isolates (vs. a perfect agreement of 100% p
