Abstract:
Bacterial resistance is spreading globally due to excessive use of antibiotics, making it one of our times
biggest challenges. To address this issue present study was conducted to evaluate the antibacterial activity of copper oxide nanoparticles against methicillin-resistant S. aureus (MRSA). Copper oxide nanoparticles were synthesized by chemical precipitation method and were characterized by UV-Visible, FT-IR spectroscopy, X-ray diffraction (XRD) and Scanning Electron Microscopy. These nanoparticles of 27nm were assessed for antibacterial activity using disc diffusion method. Our results showed superb inhibitory effects of CuO nanoparticles with increase in concentration and complete inhibition was recorded against tested strains of S. aureus at 100µl/ml and 125µl/ml concentration. The study concludes that the drugs which do not show any inhibitory effects against resistant bugs could be augmented with CuO nanoparticles to achieve the treatment goal.
