Abstract

BACKGROUND

Against a variety of antimicrobial resistant pathogens, the scientists attempted substitution of antimicrobial medicine with various nanoparticles and plant-based antibacterial substances.

OBJECTIVES

The aim of this study was to assess the antibacterial effects of silver nanoparticles solely and in combination with essential oil and methanolic extract on some photogenic bacteria.

METHODS

Minimum inhibitory concentrations (MICs) and fractional inhibitory concentrations (FICs) of plant essential oil, methanolic extract, and silver nanoparticles against bacteria were evaluated using the broth microdilution method and check board microtiter assays.

RESULTS

The results of the experiment showed that the MIC and minimal bacterial concentration (MBC) values of Ag-NPs against all strains were in the range of 15.625 - 500 µg/mL, and values for the essential oil and plant extract were in the range of 1.56 - 100 mg/mL.

CONCLUSIONS

Silver nanoparticles were observed to have additive effects with essential oil against and . The obtained results suggest the need for further investigations of the antibacterial effects of the combination of silver nanoparticles with other plant extracts and essential oils.

摘要

背景

针对多种抗菌耐药病原体，科学家们尝试用各种纳米颗粒和植物源抗菌物质替代抗菌药物。

目的

本研究旨在评估银纳米颗粒单独以及与精油和甲醇提取物联合使用对某些发光细菌的抗菌效果。

方法

采用肉汤微量稀释法和棋盘微量滴定法评估植物精油、甲醇提取物和银纳米颗粒对细菌的最低抑菌浓度（MIC）和分数抑菌浓度（FIC）。

结果

实验结果表明，银纳米颗粒对所有菌株的MIC和最低细菌浓度（MBC）值在15.625 - 500 µg/mL范围内，精油和植物提取物的值在1.56 - 100 mg/mL范围内。

结论

观察到银纳米颗粒与精油对[具体菌株1]和[具体菌株2]有相加作用。所得结果表明需要进一步研究银纳米颗粒与其他植物提取物和精油联合使用的抗菌效果。
