“…Nutrient agar plates were prepared and swabbed with 100 μl of mature broth culture of human pathogenic bacterial strains individually. Firstly, the pathogens sensitivity was tested by using the standard antibiotics 58 (Amikacin 30 mcg, Ampicilin/sulbactam 40 μg, Ampicillin 10 μg, Cefotaxime 30 µg, Cefoxitin 30 µg, Cephradine 30 μg, Chloramphenicol 30 mcg, Erythromycin 15 mcg, Gentamicin 10 mcg, Nitrofurantion 300 mcg, Norfloxacin 10 mcg, Pefloxacin 5 mcg and Penicillin G 10 U) through disc diffusion method 23 – 25 , 43 , 50 , 59 , 60 . Secondly, the minimum inhibitory concentration (a concentration which completely inhibited growth) were calculated by using different concentration of pure nano-MgO solution (5, 10, 15, 20, 25, 30, 35, 40, 45, 50 and 55 µg/ml) through well diffusion method.…”
