Extensive documentation is available on plant essential oils as a potential source of antimicrobials, including natural drugs against spp. Yeasts of the genus are responsible for various clinical manifestations, from mucocutaneous overgrowth to bloodstream infections, whose incidence and mortality rates are increasing because of the expanding population of immunocompromised patients. In the last decade, although is still regarded as the most common species, epidemiological data reveal that the global distribution of spp. has changed, and non- species of are being increasingly isolated worldwide. The present study aimed to review the anti- activity of essential oils collected from 100 species of the Lamiaceae family growing in the Mediterranean area and the Middle East. An overview is given on the most promising essential oils and constituents inhibiting spp. growth, with a particular focus for those natural products able to reduce the expression of virulence factors, such as yeast-hyphal transition and biofilm formation. Based on current knowledge on members of the Lamiaceae family, future recommendations to strengthen the value of these essential oils as antimicrobial agents include pathogen selection, with an extension towards the new emerging Candida spp. and toxicological screening, as it cannot be taken for granted that plant-derived products are void of potential toxic and/or carcinogenic properties.
关于植物精油作为抗菌剂潜在来源的文献资料丰富,包括针对某些菌种的天然药物。假丝酵母属的酵母菌会引发各种临床表现,从粘膜皮肤过度生长到血流感染,由于免疫功能低下患者群体不断扩大,其发病率和死亡率正在上升。在过去十年中,尽管白色念珠菌仍被视为最常见的菌种,但流行病学数据显示,假丝酵母属菌种的全球分布已经发生变化,非白色念珠菌菌种在世界范围内的分离频率越来越高。本研究旨在综述从地中海地区和中东地区生长的100种唇形科植物中提取的精油的抗假丝酵母活性。概述了最有前景的抑制假丝酵母属菌种生长的精油和成分,特别关注那些能够降低毒力因子表达的天然产物,如酵母-菌丝转变和生物膜形成。基于目前对唇形科植物成员的了解,加强这些精油作为抗菌剂价值的未来建议包括病原体选择,扩大到新出现的假丝酵母属菌种,以及毒理学筛选,因为不能想当然地认为植物源产品没有潜在的毒性和/或致癌特性。
