Bаcteriаl sensitivity tо аntibiоtics can be evaluated by the disk-diffusiоn (Kirby-Bauer) test where filter-paper disks impregnated with antibiotics are placed on the surface of an agar plate swabbed uniformly with bacteria. The figure below illustrates the result of this test when equal concentrations of five different antibiotics (A-E) were used. Each antibiotic had the same diffusion characteristics. To which antibiotic is this bacterial culture most resistant (least sensitive) to?
