Prebiotics and community composition influence gas production of the human gut microbiota

This study shows that prebiotic chemical composition and gut microbiota community structure influence gas production during fermentation, with common metabolisms like H2 production depending on substrate and rare ones like methane on microbial presence.

Aerodigestive sampling reveals altered microbial exchange between lung, oropharyngeal, and gastric microbiomes in children with impaired swallow function

This study examines microbial exchange between lung, oropharyngeal, and gastric microbiomes in children with impaired swallow function, finding increased similarity between lung and oropharyngeal microbiomes in those with aspiration.

Orthogonal dietary niche enables reversible engraftment of a gut bacterial commensal

This study shows that introducing a gut bacterial commensal with exclusive access to a novel dietary resource, seaweed, enables its colonization in mice, but long-term stability is diet-dependent and subject to immune regulation.

Predictability and persistence of prebiotic dietary supplementation in a healthy human cohort

The paper investigates the predictability of gut microbiota responses to prebiotic dietary supplementation in a healthy human cohort, finding strain-level predictability and no reduction in microbiota variability.
