摘要

背景 人类肠道微生物群在婴儿期迅速发展,这是一个与适应性免疫系统成熟相吻合的关键发育窗口期。然而,人们对婴儿出生后头几个月的微生物群生长动态以及人类群体中是否存在任何可推广的模式知之甚少。我们对一组婴儿(15 人)的粪便样本(94 份)进行了元基因组测序,这些样本在出生后的头六个月中每月采集一次,我们的数据集得到了七项已发表研究的补充,共有来自 1162 名婴儿的 4,441 个元基因组。

Strain-level characterization of health-associated bacterial consortia that colonize the human gut during infancy
Background The human gut microbiome develops rapidly during infancy, a key window of development coinciding with maturation of the adaptive immune system. However, little is known of the microbiome growth dynamics over the first few months of life and whether there are any generalizable patterns across human populations. We performed metagenomic sequencing on stool samples (n=94) from a cohort of infants (n=15) at monthly intervals in the first six months of life, augmenting our dataset with seven published studies for a total of 4,441 metagenomes from 1,162 infants.
