The World Health Organization highlights the urgent need to address the global threat posed by antibiotic-resistant bacteria. Efficient and rapid detection of bacterial response to antibiotics and their virulence state is crucial for the effective treatment of bacterial infections. However, current methods for investigating bacterial antibiotic response and metabolic state are time-consuming and lack accuracy. To address these limitations, we propose a novel method for classifying bacterial virulence based on statistical analysis of nanomotion recordings. We demonstrated the method by classifying living bacteria in the virulent or avirulence phase, and dead bacteria, based on their cellular nanomotion signal. Our method offers significant advantages over current approaches, as it is faster and more accurate. Additionally, its versatility allows for the analysis of cellular nanomotion in various applications beyond bacterial virulence classification.
世界卫生组织强调迫切需要应对抗生素耐药细菌所构成的全球威胁。高效快速地检测细菌对抗生素的反应及其毒力状态对于有效治疗细菌感染至关重要。然而,目前用于研究细菌抗生素反应和代谢状态的方法既耗时又缺乏准确性。为了克服这些局限性,我们提出了一种基于纳米运动记录的统计分析来对细菌毒力进行分类的新方法。我们通过根据活细菌的细胞纳米运动信号对处于有毒或无毒阶段的活细菌以及死细菌进行分类,展示了该方法。我们的方法相对于目前的方法具有显著优势,因为它更快且更准确。此外,其通用性使得它能够在细菌毒力分类之外的各种应用中分析细胞纳米运动。
