Understanding how ESBL E. coli affects the gut microbiome in infants

Investigating the impact of ESBL E. coli colonization on infant microbiome

NIH-funded research Lurie Children's Hospital of Chicago · NIH-10884428

This study is looking at how certain bacteria that can cause infections affect the gut health of babies, focusing on when these bacteria show up and how food might influence their impact on the gut.

What this research studies

This research investigates the effects of colonization by extended spectrum beta-lactamase-producing E. coli on the gut microbiome of infants. It aims to understand how these bacteria, which can cause serious infections, impact the development of the gut microbiome during early life. The study will analyze the timing of colonization and the role of nutrition in shaping the microbiome. By using a murine model, researchers will explore how these bacteria persist in the gut and their potential long-term effects on health.

Who could benefit from this research

Good fit: Ideal candidates for this research are infants who may be at risk of colonization by ESBL E. coli, particularly those born in settings where such bacteria are prevalent.

Not a fit: Patients who are older than 21 years or those who have not been exposed to ESBL E. coli may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved strategies for preventing infections in infants and better understanding of gut health.

How similar studies have performed: Previous studies have shown that understanding gut colonization in early life can significantly impact health outcomes, indicating that this research builds on established findings.
