Faculty, Staff and Student Publications

Dietary components influence microbial composition in the digestive tract. Although often viewed as energy sources, dietary components are likely to shape microbial determinants of intestinal colonization beyond metabolism. Here, we report that a dietary long-chain fatty acid enhances the yeast Candida albicans colonization of the murine gut partly by eliciting modifications to the fungal cell surface. Mice fed an oleic acid-rich diet were readily colonized by C. albicans and exhibited higher fungal load in feces compared with rodents fed an isocaloric control diet. Surprisingly, β-oxidation, a catabolic process to break down fatty acids for energy production, was dispensable for C. …
