Good Morning! Highlights of today’s digest include investigation about early childhood microbiota assembly in mother-infant participants from the Tsimane indigenous population from Amazon and with findings suggesting that socioeconomic changes may be altering interactions of highly abundant members of the microbiota in the host. Results from a gut-brain axis rat model showed possibility of novel biomarkers development for stress response based on abundance of genes in microbiomes. Finally, another study is aiming to access biologically active small molecules with antibacterial activity derived from human microbiota by sequencing of metagenomes and the use of computational and synthetic biology methods.
