Synergistic Activity of Antibiotics and Bio Active Plant Extract: Astudy Against Mdr Gram Negative Bacteria in Kirkuk City

Abstract

Increasing multidrug resistance (MDR) is becoming a problematic issue worldwide.  Finding alternatives to cope with this rising problem is becoming crucial for community healthcare. The present study aimed to investigate the antibacterial activityCopper oxide nanoparticles (CuONPs) synthesised using hawthorn fruit extract against different MDR gram-negative bacteria isolates. CuoNPs were synthesized from Fresh hawthorn fruits (Crataegus). The biosynthesized copper oxide nanoparticles were Characterization of the synthesised nanoparticles was performed using UV-visible spectroscopy, Scanning Electron Microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR), and X-ray diffraction (XRD) to confirm CuONP production and assess their properties. Antibacterial activity was determined by disc diffusion and the healthy diffusion method. The considerable inhibitory action of hawthorn fruit extract was observed in gram-negative bacteria isolates. Also, the green synthesised CuoNPs demonstrated remarkable antibacterial activity against two human pathogenic bacteria when combined with commercially available antibiotics. The current study suggested that CuoNPs have become an essential approach for nanobiotechnology applications in the development of antibacterial treatments for different bacterial infections, particularly for non-treatable antibiotic resistance pathogen.
