From parent to progeny

How infants acquire their gut microbial communities and the various factors influencing these dynamics remain unclear. In this issue of Cell Host & Microbe, Selma-Royo et al. and Dubois et al. use shotgun metagenomic sequencing to understand the transmission of microbes from parents to infants and delve into factors modifying this process.
