Rapid and accurate identification of pathogens causing infections is one of the biggest challenges in medicine. Timely identification of causative agents and their antimicrobial resistance profile can significantly improve the management of infection, lower costs for healthcare, mitigate ever-growing antimicrobial resistance and in many cases, save lives. Raman spectroscopy was shown to be a useful-quick, non-invasive, and non-destructive -tool for identifying microbes from solid and liquid media. Modifications of Raman spectroscopy and/or pretreatment of samples allow single-cell analyses and identification of microbes from various samples. It was shown that those non-culture-based approaches could also detect antimicrobial resistance. Moreover, recent studies suggest that a combination of Raman spectroscopy with optical tweezers has the potential to identify microbes directly from human body fluids. This review aims to summarize recent advances in non-culture-based approaches of identification of microbes and their virulence factors, including antimicrobial resistance, using methods based on Raman spectroscopy in the context of possible use in the future point-of-care diagnostic process.
快速准确地识别引起感染的病原体是医学面临的最大挑战之一。及时鉴定病原体及其对抗菌药物的耐药性谱,可以显著改善感染的管理,降低医疗保健成本,减轻日益严重的抗菌药物耐药性问题,在许多情况下还能拯救生命。拉曼光谱已被证明是一种有用的工具,具有快速、非侵入性和非破坏性的特点,可用于从固体和液体介质中识别微生物。拉曼光谱的改进和/或样品的预处理可以实现单细胞分析和来自各种样本的微生物鉴定。研究表明,这些非培养方法也可以检测抗菌药物耐药性。此外,最近的研究表明,拉曼光谱与光学镊子相结合,有可能直接从人体体液中识别微生物。本综述旨在总结近年来利用拉曼光谱法在非培养基础上鉴定微生物及其毒力因子(包括抗菌药物耐药性)的新进展,探讨这些方法在未来即时诊断中的应用前景。
