| Ciprofloxacin (μg/mL) | 100 | 18.0 ± 0.2a | 27.0 ± 0.0b | 29.1 ± 0.3c |
SA – S. aureus, PA – P. aeruginosa, EC – E. coli, DIZ – Diameter of Inhibitory Zone.
All the data is presented as mean ± SD of the three replicates. Mean followed by a different letter in the same row differs significantly (p ≤ 0.05).
