Oral Microbiota & Bacterial Disease Program

The Oral Microbiota and Bacterial Disease Program in the Integrative Biology and Chronic Diseases Branch supports extramural basic and translational research on the role of oral microbes in health and disease. The program supports research in four broad scientific areas:
  • Biofilms and Microbial Ecology
  • Microbial Polyomics
  • Microbial Pathogenesis
  • Prevention and Treatment Strategies that provide the basis for rapid development of knowledge of the etiology, pathogenesis, diagnosis, treatment, and prevention of oral infectious diseases.
