Microbiota and Health Study (Dhaka, Bangladesh). Homo sapiens

The Microbiota and Health Study (clinicaltrials.gov: NCT02361164) was a longitudinal, community-based cohort study in Nandipara, a peri-urban community of Dhaka, Bangladesh conducted from April 2013 to October 2016. 267 newborns born to healthy mothers were followed from birth to two years of age. Fecal samples were collected at birth, during subsequent scheduled visits, and when possible during illness episodes. Active surveillance of diarrheal and respiratory infections was conducted by a community-based team of nurses supervised by a physician. Fecal samples of 222 participants were analyzed using metagenomic sequencing to characterize any undescribed gut microbial diversity and downstream contributions to gut metabolism.
