Evaluation of antimicrobial activity of silver nanoparticle using Eichhornia crassipes leaves extract

Abstract

This study highlights the synthesis of silver nanoparticles using Eichhornia crassipes leaves extract. Antibacterial activity of silver nanoparticles was assessed by using disc diffusion method against Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Candida albicans, Aspergillus flavus, since Bacillus species and S. aureus strains may cause diarrhoea and an enteropathogenic form of E. coli. Candida albicans is the most common cause of fungal urinary tract infections, intense itching, swelling, and irritation. Aspergillus flavus include chronic granulomatous sinusitis, keratitis, cutaneous aspergillosis, wound infections and osteomyelitis following trauma and inoculation. The results of this study clearly indicate that silver nanoparticles synthesized from plant extract of Eichhornia crassipes has many pharmaceutical applications for the control of deadly pathogens.
