Silver Nanoparticles as an Effective Anti-Nanobacterial System towards Biofilm Forming Pseudomonas oryzihabitans

Abstract

Silver nanoparticles have been considered a powerful antimicrobial agents recently especially after increasing incidence of diseases associated with biofilm and multi-drug resistant pathogens required to find a novel path to eradicate that challenge. The present study aims to evaluate the antibacterial activity of biosynthesized silver nanoparticles (AgNPs) using a cell-free extract of Enterobacter cloacae and chemo synthesis by sodium borohydride (NaBH 4 ) on biofilm-forming Pseudomonas oryzihabitans. Antimicrobial effect of silver nanoparticles in both types and in combination with imipenem were evaluated by agar well diffusion method. The results revealed a good response to inhibit biofilm-forming Pseudomonas oryzihabitans growth by silver nanoparticles antibacterial activity in both types (biological and chemical) and in combination with imipenem; the antimicrobial effect was increased and enhanced. In the present study, it was found that the biological and chemical silver nanoparticles were considered a novel and decisive solution against biofilm and multi-drug resistance bacteria with a preference of biological silver nanoparticles.

“…Nanomaterials possess enhanced physicochemical properties and biological activities in comparison with the bulk materials. This property makes nanoparticles useful in different fields of science and technology [1][2][3][4][5][6][7][8][9][10][11]. Researchers emphasize on silver nanoparticles because of its opportunity in the field of high information storage, electroluminescence and photoluminescence devices [12].…”
