DD: disc diffusion. WD: well diffusion. The symbol — indicates no inhibition zone formation. Inhibition degrees: inactive (<9 mm inhibition zone), partially active (9–12 mm inhibition zone), active (12–18 mm inhibition zone), and active (>18 mm inhibition zone) [48]. The data are expressed as mean ± standard deviation. indicates statistical difference between the disc and well diffusion technique data, according to Student’s -test at 5% probability. |
