Background and Objectives: Synthesis of silver nanoparticles (AgNPs) using plant extract is cost effective, while, one of the applications of AgNPs is its antimicrobial and anti-biofilm activities. The aim of this study was to investigate the anti-biofilm activity of synthesized AgNPs using A. dendroides against antibiotic resistant and biofilm forming clinical isolates of Klebsiella pneumoniae.Materials and Methods: In this laboratory study, the AgNPs were first synthesized using Asphodelus dendroides extract and their size and structural characteristics were determined using various physico-chemical methods. Subsequently, the antimicrobial and anti-biofilm activities of synthesized AgNPs on antibiotic resistant and biofilm forming clinical isolates of K. pneumoniae were investigated via minimum inhibitory concentration (MIC) and Real Time PCR, respectively.
Conclusion: The results of this study showed the antimicrobial and anti-biofilm activities of AgNPs against K. pneumoniae strains. According to the results, with further studies, the synthesized AgNPs may be used as biofilm inhibitors in future.Key words: Silver nanoparticle, Klebsiella pneumoniae, Antibacterial activity, Anti-biofilm activity, mrkA gene
