  1. *Azithromycin and ketoconazole were used as positive controls at a concentration of 100 μg mL−1
  2. Calculated mean is for triplicate measurements from three independent experiments ± SD
  3. a–dMeans with different superscripts in the same row  are considered statistically different (LSD test, P ≤ 0.05)
