In ourstudy, silver nanoparticles exerted a bactericidal effectagainst the six bacterial strains because the MBC/MICratio values were lower than 1.2. As seen in Table 1,there was no signiï¬cant difference between the bacteri-cidal effects of silver nanoparticles on drug-resistant andnon-drug-resistant microorganisms.heantibacterial activity of silver nanoparticles against somedrug-resistant bacteria has been established, but furtherinvestigation is needed to determine whether these particlescould be an option for the treatment and prevention of drug-resistant microbial infections.
