I focus on identifying the genomic mechanisms by which the harmless commensal bacterium Dolosigranulum pigrum produces inhibitors with activity against pathobionts commonly found in the human nasal microbiota. Nasal colonization by the pathobionts Staphylococcus aureus or Streptococcus pneumoniae is a major risk factor for invasive infection by each. My project is contributing to the overall lab goal of identifying molecular mechanisms by which microbial interactions in the nasal microbiota can reduce colonization by these two pathogenic organisms.
