Synergistic Antibacterial Effect of Silver Nanoparticles Combined with Ineffective Antibiotics on Drug Resistant Salmonella typhimurium DT104.
Synergistic antibacterial activity of combined silver nanoparticles (AgNPs) with tetracycline (polykeptide), neomycin (aminoglycoside), and penicillin (β-lactam) was tested against the multidrug resistant bacterium Salmonella typhimurium DT104. Dose-dependent inhibition of Salmonella typhimurium DT104 growth is observed for tetracycline-AgNPs and neomycin-AgNPs combination with IC50 of 0.07 μg/mL and 0.43 μg/mL, respectively. There is no inhibition by the penicillin-AgNPs combination. These results suggest that the combination of the ineffective tetracycline or neomycin with AgNPs effectively inhibits the growth of this bacterium. The synergistic antibacterial effect is likely due to enhanced bacterial binding by AgNPs assisted by tetracycline or neomycin, but not by penicillin.
期刊介绍：
Journal of Environmental Science and Health, Part C: Environmental Carcinogenesis and Ecotoxicology Reviews aims at rapid publication of reviews on important subjects in various areas of environmental toxicology, health and carcinogenesis. Among the subjects covered are risk assessments of chemicals including nanomaterials and physical agents of environmental significance, harmful organisms found in the environment and toxic agents they produce, and food and drugs as environmental factors. It includes basic research, methodology, host susceptibility, mechanistic studies, theoretical modeling, environmental and geotechnical engineering, and environmental protection. Submission to this journal is primarily on an invitational basis. All submissions should be made through the Editorial Manager site, and are subject to peer review by independent, anonymous expert referees. Please review the instructions for authors for manuscript submission guidance.
