Investigating the role of specific E. coli strains in causing diarrhea in adults in Seattle

Official title: The molecular epidemiology of enteropathogenic (EPEC) and enteroaggregative (EAEC) Escherichia coli among adult patients in Seattle

Funded at University of Washington · NIH-10862184 · Data updated 2026-11-12

This study is looking at how certain types of E. coli bacteria can cause stomach illnesses in adults, especially in the U.S., by testing stool samples from people with gastroenteritis to help improve how we diagnose and treat these infections.

Who could benefit from this research

Could help

Ideal candidates for participation include adults experiencing acute or chronic diarrhea, particularly those with unexplained gastrointestinal symptoms.

Less likely to help

Patients with gastrointestinal issues caused by non-bacterial pathogens or those who do not reside in the Seattle area may not benefit from this research.

What this research studies

This research focuses on understanding how enteropathogenic (EPEC) and enteroaggregative (EAEC) strains of E. coli contribute to gastrointestinal illness in adults, particularly in high-income countries like the United States. By utilizing advanced multiplex PCR technology, the study aims to identify these bacteria in stool samples from patients experiencing gastroenteritis. The research will include both retrospective analysis of existing data and prospective collection of new samples to clarify the clinical significance of these pathogens in adult populations. This could lead to improved diagnostic and treatment strategies for gastrointestinal infections.

Why it matters

Potential benefit: If successful, this research could enhance the understanding of gastrointestinal infections in adults, leading to better diagnosis and treatment options.

How similar studies have gone: Previous studies in Europe have shown that EPEC is a common pathogen in adults with gastroenteritis, indicating that this research builds on established findings.
