Human milk harbors its own microbiota, but whether the microbes seed the infant gut and are modified by breastfeeding practices is unresolved. In this issue, Fehr et al. (2020) sequence breastmilk and infant stool samples from mother-infant dyads to investigate the co-occurrence of milk-gut bacteria and the impact of breastfeeding practices.

母乳细菌：在婴儿肠道中播种？

母乳中含有自己的微生物群，但这些微生物是否会在婴儿肠道中播种并因母乳喂养而发生改变，目前尚不清楚。在本期中，Fehr 等人。 (2020) 对母婴二人的母乳和婴儿粪便样本进行测序，以研究乳-肠道细菌的共存以及母乳喂养实践的影响。
