Antimicrobial Behavior of Zinc Oxide Nanoparticles and β-Lactam Antibiotics against Pathogenic Bacteria

Abstract

Background: Multi-drug resistance among the pathogenic bacteria poses a serious threat to public health. Nanoparticles are one of the most effective therapeutic agents. Zinc oxide nanoparticles (ZnO NPs) are well known antimicrobial agents and are regarded as nontoxic and bio-safe. The present study aims to investigate the antimicrobial effect of ZnO NPs against the bacterial strains i.e. Klebsiella pneumoniae (K. pneumoniae) and Escherichia coli (E.coli).
