The use of antibiotics has revolutionized clinical medicine. Antibiotics allow modern doctors to treat a far wider range of diseases more effectively and economically. By definition, an antibiotic is a biochemical produced by a microorganism that inhibits the growth of, or kills, another microorganism. One way to test the effectiveness of an antibiotic against a specific microorganism is the Bauer-Kirby test which measures the degree of inhibition produced by antibiotic disks (disks which contain a known amount of antibiotic) when placed on an agar dish swabbed with the desired microorganism. The antibiotic disks produce zones of inhibition (clear areas of no growth) which are measured in order to determine the susceptibility of the microorganism to the different antibiotics used in the test. You are using a newly developed substitute for the outdated Agar dish that is a product invented and developed by Dr. Jonathan Roth of Roth Bioscience, LLC, that is registered R-CARD.
