Life stage shifts in salivary microbiota determinants: a cross-sectional study in twins
Both host genetics and environmental exposures shape the salivary microbiota; however, the relative contributions of these factors from early life to adulthood remain unclear. To address this, we profiled the salivary microbiota of 3387 twin pairs: 939 infant pairs (9–12 months) and 2,448 adult pairs (23–52 years) usin...
