Microbiome assembly across multiple body sites in low-birthweight infants.

ABSTRACT:

Unlabelled

The purpose of this study was to evaluate the composition and richness of bacterial communities associated with low-birthweight (LBW) infants in relation to host body site, individual, and age. Bacterial 16S rRNA genes from saliva samples, skin swabs, and stool samples collected on postnatal days 8, 10, 12, 15, 18, and 21 from six LBW (five premature) infants were amplified, pyrosequenced, and analyzed within a comparative framework that included analogous data from normal-birthweight (NBW) infants and healthy adults. We found that body site was the primary determinant of bacterial community composition in the LBW infants. However, site specificity depended on postnatal age: saliva and stool compositions diverged over time but were not significantly different until the b
