Aim: To determine the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) of silver nanoparticles against Enterococcus faecalis (E.faecalis).
Methodology: The antimicrobial efficacy of the silver nanoparticles was determined by the standard methods of Clinical and Laboratory Standards Institute (CLSI). Different concentrations of silver nanoparticles were prepared, and MIC was calculated by tube macro dilution method. The MBC was determined by the lowest concentration that kills 99.9% of the initial bacterial population. The data was analyzed by non-parametric test of Kruskal-Wallis using SPSS software package (version 17).
Results: The MIC and MBC of silver nanoparticles against E. faecalis was found to be optimum at 5 mg/ml.
