Question

Quizplus · Accepted Answer

The microbiologist is setting up a minimum inhibitory concentration (MIC) assay. The goal of this assay is to determine the lowest concentration of an antimicrobial drug that can inhibit the growth of a specific pathogen. By making serial dilutions of the drug in broth, the microbiologist can determine the MIC of the drug for the pathogen in question.
