In this episode, we speak with Dr. Vales-Colomer, a leading researcher in the field of microbiome science. Our conversation revolves around the human microbiome, its integral role in health, and the profound influence of interpersonal relationships on its genetic makeup.

Dr. Vales-Colomer delves into his latest research, based on an analysis of over 9,700 human metagenomes. This study reveals the intricate patterns of bacterial strain transmission between individuals, demonstrating the significant role of mother-to-infant transmission, intra-household sharing, and intra-population patterns. His findings suggest that approximately half of the bacterial strains in an infant's gut microbiome are transmitted from their mother, and this transmission remains detectable even in later life stages.
