Antimicrobial susceptibility testing was performed to screen a novel compound. The MIC was found to be 10ng/mL. Use the following data to determine the percent recovery for each treatment group. What is the MBC and would you describe the antimicrobial tested as static or cidal? Explain your answer. From this result, do you suggest further study of this compound as a potential antimicrobial agent and why?
