438-人类微生物组与多病种关联的宏基因组集成分析

from 聊聊Sci

这项研究介绍并分析了 curatedMetagenomicData (cMD) 3,这是一个包含来自42个国家、超过22,000个样本的大型标准化人类微生物组数据集。研究人员利用该资源进行了大规模元分析,精准确定了与性别、年龄、体重指数(BMI)及15种疾病显著相关的数百种微生物物种和功能。研究特别提出了一种“口腔富集评分(OES)”,用于量化肠道内口腔细菌的水平,并发现该指标是衡量宿主健康状况改变的有效信号。通过机器学习模型,科学家们证明了微生物特征在预测个体生理特质和疾病状态方面具有高度的跨研究可重复性。该成果不仅揭示了人类微生物组广泛存在的共有模式,还为未来的流行病学研究提供了重要的参考基准和工具。References: Manghi P, Antonello G, Schiffer L, et al.
