Effects of topical antimicrobials on skin bacteria in households with Staphylococcus aureus

Microbial Community Disruption Following Topical Antimicrobial Application in Staphylococcus aureus-Affected Households

NIH-funded research Washington University · NIH-11093991

This study is looking at how using skin and nasal treatments can change the bacteria on your skin and in your nose if you live with someone who has Staphylococcus aureus, and it aims to find ways to prevent infections without making antibiotic resistance worse, so you might be asked to share your experiences and provide some samples.

What this research studies

This research investigates how the application of topical antimicrobials affects the microbial communities on the skin and in the nasal passages of individuals living in households with Staphylococcus aureus. By analyzing over 13,000 skin and nasal swabs, the study aims to understand the balance between beneficial and harmful bacteria and how antimicrobial treatments may disrupt this balance. The goal is to identify strategies that can prevent infections while minimizing the risk of developing antibiotic-resistant bacteria. Patients may be asked to provide samples and participate in discussions about their experiences with antimicrobial treatments.

Who could benefit from this research

Good fit: Ideal candidates for this research are adults living in households affected by Staphylococcus aureus, particularly those who have used topical antimicrobials.

Not a fit: Patients who do not live in households with Staphylococcus aureus or who have not used topical antimicrobials may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved strategies for preventing Staphylococcus aureus infections while preserving healthy skin microbiota.

How similar studies have performed: Previous research has shown that understanding microbial communities can lead to better infection control strategies, indicating potential success for this approach.
