Abstract
Azadirachta indica is a multipurpose tree with multiple health benefits. Different parts of the plant are shown to exhibit antimicrobial effects against a wide variety of micro organisms. In the present study we investigate the antibacterial activity of Azadirachta indica extract against UTI (urinary tract infection) causing bacteria. Silver nanoparticles could be synthesized using the leaves of Azadirachta indica as reducing agent. The resulting silver nanoparticles were characterized using UV-Vis spectrophotometer, X-ray Diffraction (XRD), Scanning Electron Microscope (SEM), and Fourier Transformations Infra Red (FTIR) spectroscopic analysis. The antibacterial activity was assayed by Agar well diffusion method using 20µl each of sterile Nutrient Agar (NA) (Hi-Media) and Potato-Dextrose Agar (PDA). The resulting silver nanoparticles exhibited best inhibitory activities against Escherichia coli and Proteus mirabilis which are main causing agents for UTI.
