What this research studies

We are looking into how antibiotics a breastfeeding mother takes for common infections might affect her baby's gut bacteria and metabolism. This is important because a baby's early gut health can have long-term effects on their overall well-being. We plan to use gentle skin swabs to check for antibiotic levels in babies, which is a new way to monitor drugs without needing blood draws. We will also examine infant stool samples to see how their gut bacteria and body chemistry change.

Who could benefit from this research

Good fit: Ideal candidates would be breastfeeding mothers who are taking antibiotics for common infections and their infants.

Not a fit: Patients who are not breastfeeding or whose mothers are not taking antibiotics would not directly benefit from participating in this specific research.

Why it matters

Potential benefit: If successful, this work could help us better understand the long-term health effects of maternal antibiotic use on infants and potentially guide future recommendations for breastfeeding mothers.

How similar studies have performed: This project utilizes innovative methods like untargeted metabolomics and non-invasive skin swabs, suggesting a novel approach to monitoring drug effects in infants.
