The aim of this study was to investigate the antibacterial effects of Ganoderma+silver extract complex nanocomplex on bacteria causing nosocomial infections including Streptococcus pyogenes, Staphylococcus aureus, Pseudomonas aeruginosa and Acinetobacter baumannii. In the present study, silver nanoparticles were first loaded on Ganoderma extract. Then, tests such as FTIR and scanning electron microscopy were performed to confirm the loading of silver nanoparticles on Ganoderma extract. Then, the effects of nanocomplexes on Vero cell line were investigated to determine the toxicity of this compound on the cell. Also, the antibacterial properties of nanocomplexes of Ganoderma+silver extract on the studied bacteria were investigated. The MIC results of the fungus+silver nanocomplex were observed on Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus pyogenes and Acinetobacter baumannii at 875, 218.75, 109.375 and 54.68, respectively. The results of this study showed that this complex has no toxic effect on eukaryotic cell line. Therefore, the synthesis of Ganoderma+silver nanocomplex can be used in medicine and food industry as an innovative, economical and environmental antimicrobial agent.
