Scientists use the zone of inhibition test to study antibiotic resistance of bacteria. The wafers on the culture medium contain an antibiotic that inhibits growth of sensitive bacteria in their ...

A clear area (zone of inhibition) indicates that the bacteria have been killed by the solution or have not been able to reproduce. Soak small (5 mm) filter paper disks in a variety of solutions ...

A zone of inhibition of growth around the Taxos disc indicates that the organism is susceptible/sensitive to that antibiotic. Obtain a fresh BAP (1 plate per group of 4) and divide it into quadrants.

This value may vary slightly in a specific question. Measure the diameter of the zone of inhibition and divide it by 2 to calculate the radius, (r), eg 10 / 2 = 5 mm Use the equation: πr 2 ...
