How Staph (including MRSA) spreads and resists antibiotics in hospitals and communities

Staphylococcus aureus SPREAD (S. aureus Study of Prevalence Resistance and Environmental Dissemination)

NIH-funded research University of Pennsylvania · NIH-11111438

This project uses whole-genome sequencing of Staphylococcus aureus from patients, healthcare workers, and room surfaces in two hospital units to see how strains spread and cause infections in people admitted to the hospital.

What this research studies

If I'm admitted to one of the two study units, researchers will swab four body sites on admission to check for Staph colonization and will follow some patients' room surfaces and nearby healthcare workers for the bacteria over 24 months. They will sequence the bacterial DNA to match strains between people and surfaces and compare findings to control patients who are not colonized on admission. The team will look for how often bacteria move from person to person, whether some strains spread more easily, and whether fomites or staff bodies act as intermediate carriers. Results will link carriage at admission with later infections to guide prevention.

Who could benefit from this research

Good fit: Ideal candidates are people admitted to one of the two participating units at the Hospital of the University of Pennsylvania who agree to admission swabs and, for some, room surface or staff-contact sampling.

Not a fit: People not admitted to the participating units, those who decline swabbing, or patients whose infections come from unrelated sources may not receive direct benefit from this project.

Why it matters

Potential benefit: If successful, this work could help hospitals reduce Staph and MRSA infections by identifying common transmission routes and improving screening, cleaning, and staff practices.

How similar studies have performed: Prior outbreak investigations using whole-genome sequencing have successfully traced Staph transmission in hospitals, but combining routine admission swabs, systematic room surface sampling, and staff sampling over two years is less common.
