Impact of geographic residency on breast milk, infant gut microbiota, and short-chain fatty acids

The influence of geographical residency on the composition and interactions among milk and gut microbiota and their metabolites, including short chain fatty acids (SCFAs), remains unclear. To fill this gap in information, infant stool (0 to 12 months) and breast milk samples (1 to 30 days postpartum) were collected from 69 dyads living in rural or urban Manitoba for microbiota and SCFA analyses using 16S rRNA sequencing or gas chromatography mass spectrometry.
