Abstract

The recent study included biosynthesis of Zinc oxide nanoparticles by Lantana camara flower extract and investigate their biological potential toward pathogenic bacteria isolated from wounds infections. Characterization were made by U.V.-Visibl light Spectroskop,X-Ray Diffraction XRD ,Feild Emmission Scan Electron microscope FE-SEM , the results showed that the UV peaks were at 384.5 nm , XRD analysis estimated the crystallites sizes in 22.5 nm . FE-SEM analysis displayed average particles size were 45.15 nm . Clinical samples 100 were collected during October 2021 to the end of Febreuary 2022 from cared patients who have acute and chronic wounds infections, Isolation and identification by biochemical tests were done, susceptibility test was investigated and antibacterial potential of ZnO nanoparticles was tested toward three clinical strains of S. aureus , K. oxytoca and Proteus vulgaris. that found to be resistance to at least three types of antibiotics in diffrernt antibiotics groups. The inhibition zones were observed at the concentration 200 mg/ml (25,22.5,21) mm. Sensitivity of the bacterial isolates to ZnO NPs was diagnosed by determination of Minimum inhibitory concentration by using microdilution method.
