Strain-level translocation and enrichment dynamics of oral bacteria in the lower gastrointestinal tract of stunted children

nucleotide diversity compared to other compartments, which is consistent with frequent intraindividual translocations from the oral cavity to the lower gastrointestinal tract. Finally, we showed that overrepresentation of oral bacteria in the duodenum of stunted children is related to increased biomass, while in the colon, it is linked to depletion of overall biomass, including in butyrate-producing strains. Our study quantifies dynamics of oral-to-gut translocation and enrichment of oral taxa, providing key insights into microbiota disruption in stunted children.

Abstract

nucleotide diversity compared to other compartments, which is consistent with frequent intraindividual translocations from the oral cavity to the lower gastrointestinal tract. Finally, we showed that overrepresentation of oral bacteria in the duodenum of stunted children is related to increased biomass, while in the colon, it is linked to depletion of overall biomass, including in butyrate-producing strains. Our study quantifies dynamics of oral-to-gut translocation and enrichment of oral taxa, providing key insights into microbiota disruption in stunted children.
