NIH-funded research R21 grant

Investigating how Acinetobacter baumannii bacteria are stored in the human body

Official title: Acinetobacter baumannii reservoirs within the host

Funded at Washington University · NIH-11098535 · Data updated 2026-11-12

This study is looking at how a type of bacteria that can cause serious infections in hospitals might be hiding in bladder cells, even in people who don’t show any symptoms, so we can find ways to stop these infections from spreading in healthcare settings.

Who could benefit from this research

Could help

Ideal candidates for this research are patients who have undergone medical procedures that may involve catheterization or those with a history of Acinetobacter baumannii infections.

Less likely to help

Patients who do not have a history of Acinetobacter baumannii infections or who are not undergoing relevant medical procedures may not benefit from this research.

What this research studies

This research explores how the bacteria Acinetobacter baumannii, known for causing serious infections in hospitals, can be hidden within the human body, particularly in bladder cells. The study aims to understand how these bacteria can remain undetected and potentially reactivate after medical procedures, leading to infections. By using mouse models, researchers will investigate the conditions under which these bacteria can be introduced into hospitals from patients who may not show symptoms. The goal is to identify reservoirs of infection that could help prevent outbreaks in healthcare settings.

Why it matters

Potential benefit: If successful, this research could lead to improved strategies for preventing hospital-acquired infections caused by antibiotic-resistant bacteria.

How similar studies have gone: Previous research has shown that understanding bacterial reservoirs can lead to successful infection control strategies, indicating that this approach has potential for success.
