Abstract Silver bionanoparticles (AgNPs) have been known to have inhibitory and bactericidal effects. Resistance to antimicrobial agents by pathogenic bacteria has emerged in recent years and is a major health problem. This report focuses on the synthesis of metallic bionanoparticles of silver using a reduction of aqueous Ag+ ion with the culture supernatants of Staphylococcus aureus. The bioreduction of the Ag+ ions in the solution was monitored in the aqueous component and the spectrum of the solution measured through ultraviolet-visible spectrophotometry and characterized by atomic force microscopy. The AgNPs were evaluated for their antimicrobial activities against different pathogenic organisms. The most sensitive antimicrobial activity has been observed against methicillin-resistant S. aureus followed by methicillin-resistant Staphylococcus epidermidis and Streptococcus pyogenes, whereas only moderate antimicrobial activity was seen against Salmonella typhi and Klebsiella pneumoniae. FROM THE CLINICAL EDITOR: Silver bionanoparticles (AgNPs) were evaluated for their antimicrobial activities against different pathogenic organisms. The most sensitive antimicrobial activity has been observed against methicillin-resistant S. aureus followed by methicillin-resistant Staphylococcus epidermidis and Streptococcus pyogenes, whereas only moderate antimicrobial activity was seen against Salmonella typhi and Klebsiella pneumoniae.
