Understanding gut changes during Campylobacter infection

Official title: Mucosal and Microbiota Changes During Acute Campylobacteriosis

Run by Mayo Clinic · NCT03223077 · Data updated 2026-11-12

This study looks at how a Campylobacter infection changes the gut and whether those changes can lead to long-term bowel problems like Irritable Bowel Syndrome in people who have had the infection.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are individuals who have tested positive for Campylobacter enteritis and have not undergone abdominal surgery.

Probably not a fit

Patients with a history of IBS, inflammatory bowel disease, or recent gastroenteritis may not benefit from this study.

What this trial studies

This observational study investigates how gastrointestinal infections caused by Campylobacter affect the gut microbiota and mucosal lining. Researchers aim to identify changes during acute infection that may indicate a risk for developing chronic bowel issues, such as Irritable Bowel Syndrome (IBS). The study focuses on individuals who have tested positive for Campylobacter enteritis and examines various factors that may contribute to post-infectious IBS. By analyzing gut bacteria and mucosal changes, the study seeks to enhance understanding of the relationship between acute infections and long-term gastrointestinal health.

Why it matters

Potential benefit: If successful, this study could help identify individuals at risk for developing chronic gastrointestinal disorders after infection.

How similar studies have gone: Other studies have shown that changes in gut microbiota can be linked to post-infectious IBS, suggesting potential for success in this approach.
