Who could benefit from this research

Could help

Infants and young children, particularly those who have received antibiotics in their first year of life.

Less likely to help

Children without early antibiotic exposure or those not at risk for asthma may have little direct benefit from the findings.

What this research studies

This project looks at how antibiotics given in infancy could alter the gut and airway microbiomes in ways that affect asthma risk. Researchers will identify when infants are most affected by antibiotics and which microbial changes are linked to later asthma. The study aims to find bacterial species or microbial products that could promote resilience against asthma after antibiotic exposure. By using advanced microbiome techniques, the work seeks to uncover targets for interventions to prevent asthma from developing in early childhood.

Why it matters

Potential benefit: If successful, the findings could guide timing and approaches to antibiotic use and point to microbiome-based strategies to reduce childhood asthma.

How similar studies have gone: Previous studies have linked early antibiotic exposure to asthma risk, but this project advances understanding by identifying specific ages and microbial pathways.
