Antimicrobial susceptibility testing determines whether these bacteria are susceptible or resistant to a particular antibiotic. Bacteria are added onto plates of solid agar, where each plate has a different and increasing concentration of antibiotic than the previous plate. The minimum inhibitory concentration (MIC) is the lowest concentration of an antimicrobial that inhibits growth of the bacteria.
