What is a zone of inhibition and what does it indicate?

(microbiology) The clear region around the paper disc saturated with an antimicrobial agent on the agar surface. Supplement. The clear region is an indication of the absence, or the effective inhibition, of microbial growth by the antimicrobial agent. ( see disk-diffusion test)

Just so, how do you determine the minimum inhibitory concentration?

Minimum inhibitory concentrations (MICs) are defined as the lowest concentration of an antimicrobial that will inhibit the visible growth of a microorganism after overnight incubation, and minimum bactericidal concentrations (MBCs) as the lowest concentration of antimicrobial that will prevent the growth of an organism

What is MIC and MBC?

The minimum bactericidal concentration (MBC) is the lowest concentration of an antibacterial agent required to kill a particular bacterium. It can be determined from broth dilution minimum inhibitory concentration (MIC) tests by subculturing to agar plates that do not contain the test agent.

What is minimum inhibitory concentration interpretation?

The MIC, or minimum inhibitory concentration, is the lowest concentration (in μg/mL) of an antibiotic that inhibits the growth of a given strain of bacteria. Next to each antibiotic is the susceptibility interpretation: S (sensitive), I (intermediate), or R (resistant), followed by the MIC in μg/mL.
