In disc diffusion assay of antibiotic, when an antibiotic is capable of killing the bacteria, there will be an area which surround the antibiotic disc, where there will be no bacterial growth. This area is known as zone of inhibition. So bigger the area, more effective the antibiotic is. Now looking at the table , the known bacteria, sreptococuus salinarius, produce the zone of inhibition when different antibiotic were given. The larger zone of inhibition was obtained from both tetracyclin and streptomycin. both are 41 mm. So both the antibiotic are affective against this bacteria. Whereas, for bacteria which has been obtained from dirty hand Erythromycine ( area is 110mm)is most effective.
