Who could benefit from this research

Could help

This foundational research does not directly involve patient participation, but future studies building on this work may seek individuals with specific oral or systemic health conditions.

Less likely to help

Patients looking for immediate new treatments or direct clinical intervention will not find it through this foundational research.

What this research studies

Our mouths and noses are home to many different types of germs, collectively called the microbiome, which play a big role in our health and disease. This project creates a comprehensive online database, the Human Oral Microbiome Database (eHOMD), that catalogs these microbes and their genetic information. We are also growing previously unknown oral and nasal bacteria in the lab and adding information about the viruses that infect these microbes. This foundational work helps researchers worldwide connect specific germs to health conditions and develop new ways to keep us healthy.

Why it matters

Potential benefit: This work could lead to new discoveries about how the oral microbiome affects diseases, potentially guiding future treatments or prevention strategies for various health issues.

How similar studies have gone: This project builds upon many years of successful work in creating and expanding the Human Oral Microbiome Database and cultivating new bacterial strains.
