Nanoparticles include multiple metal oxides such as yttrium, copper, nickel, zinc, iron, and silver that have antimicrobial activity. The present work evaluates the antibacterial activity of some nanoparticles (NPs)against various pathogenic bacterial strains (Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia and Staphylococcus aureus). Antimicrobial activity of NPs was accomplished by the mean of disk diffusion assay using dilutions of (200, 100, 50, 25, and 12.5) and the MIC and MBC of each isolate is determined. NPs shows no antibacterial activity against tested bacteria. It is highly recommended using NPs as an economical alternative antibacterial agent, especially in treating ectopic infections but with high concentration since low concentration gives no result without taking the risk of developing resistant bacterial strains as with antibiotics.
