How gut microbes change food and affect bacterial infections

Diet transformation by the microbiome and its impact on bacterial infection

NIH-funded research Yale University · NIH-11095888

This project looks at how the bacteria in your gut change compounds in food and how that can influence risk of food‑borne infections like Salmonella and Campylobacter.

What this research studies

Researchers will study how gut microbes chemically transform molecules from the diet and how those changes help or hinder food‑borne bacteria. The team will combine laboratory work, animal models, and analysis of microbial enzymes to track which dietary compounds get altered and by which microbes. They will focus on common pathogens spread through poultry, such as Salmonella Typhimurium and Campylobacter jejuni, to see how diet‑microbiome interactions affect whether these germs can take hold. The goal is to identify dietary or microbiome targets that could be changed to reduce infection risk.

Who could benefit from this research

Good fit: People at risk for or recovering from food‑borne bacterial infections—especially those with recent Salmonella or Campylobacter illness—or volunteers willing to provide stool samples and dietary information would be ideal for related participation.

Not a fit: Patients with infections unrelated to food‑borne bacteria, or those who cannot provide stool samples or make dietary changes, are unlikely to benefit directly from this research.

Why it matters

Potential benefit: If successful, this work could lead to dietary recommendations or microbiome‑based strategies that lower the chance of getting food‑borne bacterial infections.

How similar studies have performed: Prior animal and some human studies show the gut microbiome can block pathogens, but targeting specific microbial enzymes that modify dietary compounds is a newer and less tested approach.
