However, our understanding of how gut bacteria promote ST:STUDY_SUMMARY or restrict overgrowth of Candida species in the human gut is still limited. By ST:STUDY_SUMMARY integrating mycobiome and shotgun metagenomics data from stool of 75 patients at ST:STUDY_SUMMARY risk but with no systemic candidiasis, we revealed that bacterial communities ST:STUDY_SUMMARY from high Candida samples had greater metabolic potential whereas communities ST:STUDY_SUMMARY from low Candida had greater functional redundancy. In addition, we developed ST:STUDY_SUMMARY machine learning models that used only bacterial taxa or functional relative ST:STUDY_SUMMARY abundances to predict the levels of Candida genus and species in an external ST:STUDY_SUMMARY validation cohort with an area under the curve of 78.6-81.1%. Last, we proposed ST:STUDY_SUMMARY an intriguing mechanism for Candida species overgrowth based on a decrease in ST:STUDY_SUMMARY short-chain fatty acid producing-bacteria resulting in increased oxygen levels. ST:STUDY_SUMMARY These conditions create a metabolic niche for Candida species to use lactate as ST:STUDY_SUMMARY a carbon source and overtake their fungal competitors in the human gut.
