Suppose you do the test on a hypothetical Staphyloccocus species with the antibiotics penicillin (P 10) and chloramphenicol (C 30). You record zone diameters of 25mm the chloramphenicol and penicillin disks. Which antibiotic would be more effective against this organism?what does this tell you about comparing zone diameters to each other and the importance of the zone diameter interpretive chart?
