576-婴儿双歧杆菌全球基因组图谱与益生菌设计

from 聊聊Sci

这项研究通过构建一个庞大的长双歧杆菌(BIL)基因组图谱,揭示了婴儿型双歧杆菌(BI)与长双歧杆菌(BL)在遗传学和功能上的显著差异。研究表明,这两类细菌应被视为独立的物种,因为它们在代谢母乳成分、维生素合成及地理演化路径上表现出明显的适应性差异。调查发现,工业化国家婴儿肠道中BI的流行率显著下降,且现有的商业益生菌往往难以在不同地理背景的婴儿体内成功定植。此外,研究识别出了新的亚种级别分子标记,能够更精准地监测婴儿肠道健康。作者建议,未来的益生菌研发应结合当地饮食与族群特征,开发具有地理针对性的定制化产品。References: Genomic atlas of Bifidobacterium infantis and B. longum informs infant probiotic designShao, Yan et al.Cell, Volume 0, Issue 0前往小宇宙评论区与主播互动
