Understanding how Salmonella competes with gut bacteria

Official title: Applied Metatranscriptomics and Metatranslatomics to identify new mechanisms of Salmonella-microbiota competition

Funded at University of California, San Diego · NIH-11090491 · Data updated 2026-11-12

This study looks at how the Salmonella bacteria interact with the good bacteria in our gut, aiming to understand how Salmonella takes over and what that means for our gut health, which could lead to better treatments for infections.

Who could benefit from this research

Could help

Ideal candidates for participation or benefit include individuals with gastrointestinal issues or those at risk of Salmonella infections.

Less likely to help

Patients with no gastrointestinal concerns or those not at risk for Salmonella infections may not receive any benefit from this research.

What this research studies

This research investigates the interactions between the pathogen Salmonella enterica and the gut microbiota, focusing on how Salmonella establishes itself in the gut and outcompetes beneficial bacteria. By using advanced techniques like metagenomics, metatranscriptomics, and metatranslatomics, the study aims to uncover the specific mechanisms of competition and resource allocation in the gut environment. Patients may benefit from insights gained about gut health and potential new treatments for infections caused by Salmonella.

Why it matters

Potential benefit: If successful, this research could lead to new strategies for preventing and treating Salmonella infections by enhancing our understanding of gut microbiota interactions.

How similar studies have gone: Other research has shown success in understanding microbial interactions in the gut, making this approach promising yet still exploring novel aspects.
