ABSTRACT Enterococcus faecalis sortase-assembled endocarditis and biofilm-associated pili (Ebp) are virulence factors implicated in enterococcal infections gastrointestinal colonization. We previously showed that E. biofilm metabolism is influenced by extracellular electron transfer (EET) under iron-rich conditions, raising the question of whether Ebp also play a role EET. Here, we report novel adhesion to iron oxides magnetite, goethite, hematite, where EbpA tip adhesin contributes this interaction. Adhesion conditionally important for EET oxides, as pilus mutants attenuated non-static growth conditions. In alignment with established redox homeostasis, find ferricyanide supports anaerobic on glycerol. Furthermore, an antibiotic-treated mouse colonization model, show deficient poorly colonize intestinal niche. Taken together, our findings suggest can influence metabolic fitness promoting new questions about how shape interactions environmental ecosystems. Additionally, dysbiotic environment highlights need further inquiry into microbial pathogenesis. IMPORTANCE study, explored interplay between factor, (Ebp). demonstrate have which consequently promotes Along be coupled cell growth, results point potential ecological natural environments, outside its function host ligands. provide first evidence contribution murine niche, adds limited experimental linking pathogenesis, well studies bacterial pathogens.
