Understanding how antibiotic-resistant infections return

Genetic and phenotypic adaptations of vancomycin-resistant Enterococcus faecium during recurrent bloodstream infection

NIH-funded research University of Pittsburgh at Pittsburgh · NIH-11144425

What this research studies

VREfm is a common germ that can cause serious bloodstream infections, especially in high-risk patients, and it's hard to treat because it resists many antibiotics. Sometimes, these infections come back even after treatment. We want to understand how VREfm adapts inside the body to avoid being killed by medicines and cause these recurring problems. We will compare the genetic makeup of VREfm from patients with repeat infections to find clues about why they keep coming back. This work also explores new ways to fight these infections, like using special viruses called bacteriophages.

Who could benefit from this research

Good fit: Patients who have experienced recurrent bloodstream infections caused by vancomycin-resistant Enterococcus faecium (VREfm) are the focus of this research.

Not a fit: Patients without VREfm infections or those whose infections are easily treated with current antibiotics may not directly benefit from this specific research.

Why it matters

Potential benefit: If successful, this work could lead to better ways to treat and prevent recurring VREfm bloodstream infections, offering new hope for patients with limited options.

How similar studies have performed: While some studies have explored VREfm adaptations, systematic genomic and phenotypic assessments in recurrent VREfm infections are largely unknown, making this approach novel.
