BACKGROUND
represents an emerging pathogen that results in nosocomial infections and is considered a serious global health problem. The aim of this work was to evaluate the in vitro antifungal efficacy of essential oil (CC-EO) pure or formulated in polycaprolactone (PCL) nanoparticles against ten clinical strains of .
METHODS
nanoparticles of PCL were produced using CC-EO (nano-CC-EO) and cinnamaldehyde (CIN) through the nanoprecipitation method. The chemical profile of both CC-EO and nano-CC-EO was evaluated using SPME sampling followed by GC-MS analysis. Micro-broth dilution tests were performed to evaluate both fungistatic and fungicidal effectiveness of CC-EO and CIN, pure and nano-formulated. Furthermore, checkerboard tests to evaluate the synergistic action of CC-EO or nano-CC-EO with micafungin or fluconazole were conducted. Finally, the biofilm disrupting activity of both formulations was evaluated.
RESULTS
GC-MS analysis shows a different composition between CC-EO and nano-CC-EO. Moreover, the microbiological analyses do not show any variation in antifungal effectiveness either towards the planktonic form (MIC = 0.01 ± 0.01 and MIC = 0.02 ± 0.01) or the biofilm form. No synergistic activity with the antifungal drugs tested was found.
CONCLUSIONS
both CC-EO and nano-CC-EO show the same antimicrobial effectiveness and are potential assets in the fight against
背景
是一种新兴病原体，可导致医院感染，被视为严重的全球健康问题。本研究的目的是评估纯的或聚己内酯（PCL）纳米颗粒制剂形式的精油（CC-EO）对十种临床菌株的体外抗真菌效果。
方法
通过纳米沉淀法使用CC-EO（纳米CC-EO）和肉桂醛（CIN）制备PCL纳米颗粒。使用固相微萃取采样随后进行气相色谱-质谱分析来评估CC-EO和纳米CC-EO的化学特征。进行微量肉汤稀释试验以评估CC-EO和CIN纯品及纳米制剂形式的抑菌和杀菌效果。此外，进行棋盘试验以评估CC-EO或纳米CC-EO与米卡芬净或氟康唑的协同作用。最后，评估两种制剂的生物膜破坏活性。
结果
气相色谱-质谱分析显示CC-EO和纳米CC-EO之间的组成不同。此外，微生物学分析表明，无论是对浮游形式（MIC = 0.01±0.01和MIC = 0.02±0.01）还是生物膜形式，抗真菌效果均无任何差异。未发现与所测试的抗真菌药物有协同活性。
结论
CC-EO和纳米CC-EO均显示出相同的抗菌效果，是对抗……的潜在有效物质
