Effect of Magnesium Oxide Nanoparticles on Biofilm Formation Against Multidrug Resistant Klebsiella Pneumoniae Isolates
Subject area: Biological & Medical Sciences · Area of research: Microbiology
Abstract
The main purpose of this investigation was to access the impact on biofilm formation, antibacterial activity and anticancer potential of magnesium oxide nanoparticles (MgO NPs) against three multidrug resistant Klebsiella pneumoniae isolates. Agar well diffusion method was applied for the evaluation of antibacterial potential and maximum activity was reported at 2mg in all three isolates (21mm, 29mm, 34mm). MIC and MBC were calculated by broth micro-dilution method, two isolates showed MIC at 1000?g/ml and MBC at 2000?g/ml. While, one isolate showed MIC at 500?g/ml and MBC at 1000?g/ml. Effect of MgO nanoparticles was studied through microtiter plate assay using crystal violet stain. Magnesium oxide nanoparticles exhibited maximum reduction in biofilm formation against K.p3 isolate at the concentration of 1mg/ml that was 63.21% and on established biofilm it was 59.78%. Anticancer potential was accessed by MTT assay, research showed that anticancer activity of MgO NPs was dose-dependent manners so that the higher anticancer activity was correlated with high concentration of nanoparticles. Maximum anticancer activity was observed at the concentration of 500?g/ml that was 56.82-60.54%.
