Effects of commonly used antibiotics on children's developing gut microbiomes and resistomes in peri-urban Lima, Peru.

ABSTRACT:

Background

The effects of antibiotic use on children's gut microbiomes and resistomes are not well characterized in middle-income countries, where pediatric antibiotic consumption is exceptionally common. We characterized the effects of antibiotics commonly used by Peruvian children (i.e., amoxicillin, azithromycin, cefalexin, sulfa-trimethoprim) on gut diversity, genera, and antibiotic resistance gene (ARG) abundance from 3-16 months.

Methods

This study included 54 children from a prospective cohort of enteric infections in peri-urban Lima, 2016-2019. Stool collected at 3, 6, 7, 9, 12, and 16 months underwent DNA extraction and short-read metagenomic sequencing. We profiled the taxonomy of stool metagenomes and assessed ARG abundance by aligning reads to the ResFinder datab
