Take a ruler or caliper that measures in millimeters and place the “0” in the center of the antibiotic disk. Measure from the center of the disk to the edge of area with zero growth. Take your measurement in millimeters. This measures the radius of the zone of inhibition.
How do you calculate zone of inhibition microphone?
- Determination of minimal inhibitory concentrations (MICs)
- Weight of powder (mg) =
- Volume of solvent (ml) X Concentration (µg/ml) / Potency of powder (µg /mg)
How do you find the zone of inhibition using Kirby Bauer method?
Place the metric ruler across the zone of inhibition, at the widest diameter, and measure from one edge of the zone to the other edge. HOLDING THE PLATE UP TO THE LIGHT MIGHT HELP. Use millimeter measurements. The disc diameter will actually be part of that number.
