Research Activities

Biofilms in Human Medicine Interest Group

The goal of the Biofilms in Human Medicine  Interest Group is to define the critical factors that facilitate bacterial biofilm development in human disease and then use this knowledge to develop therapies to prevent initial infection or progression to persistent biofilms (i.e. chronic and/or persistent disease).


Biofilms, which are communities of microorganisms that are attached to a surface, play a critical role in numerous infectious diseases. The CDC and the NIH recently estimated that biofilms are responsible for 65% to 80% of all infections. In 2008, The CMIB established a multi-disciplinary translational biofilms research group that consists of microbiologists, immunologists, biochemists, pathologists, computational biologist, and infectious disease experts, as well as pulmonary and otolaryngology specialists. The team meets monthly to discuss scientific and programmatic themes with the goal to submit an NIH program project grant. The human diseases represented by the projects include cystic fibrosis, chronic gastrointestinal disease, chronic otitis media and sinusitis, dental caries, infection of the genitourinary tract, periodontitis, and device related infections. Those participating include scientists and clinicians from OSU (infectious disease, dentistry, oral biology, orthopedics, microbiology, DHLRI, and FAES) as well as Nationwide Children's Hospital and Battelle Memorial Institute.
