CdO-ZnO nanocomposite was prepared by microwave-assisted method with cadmium chloride, zinc chloride and ammonium hydroxide as starting materials and characterized by XRD, SEM and FT-IR. It exhibits hexagonal cubic structure with an average crystallite size of 22 nm. The surface morphological image displays an irregular shaped stone like structure. The UV-Vis spectra reveal the bandgap as 2.92 eV. The fluorescence spectrum shows a near band edge emission at 422 nm. The significant antimicrobial activities were studied against gram negative ( Escherichia coli, Pseudomonas aeruginosa, Proteus vulgaris and Klebsiella-pneumonia ) and gram positive ( Staphylococcus aureus, Enterococcus faecalis, Enterococci spp. and Bacillus spp .) bacteria. The zone of inhibition was found to be more for gram positive bacteria than gram positive bacteria
