This review examines how different Candida species, including the common cause of yeast infections (C. albicans) and the more dangerous bloodstream pathogen (C. glabrata), survive in the human body. While most pathogenic Candida species are metabolic generalists that can eat many different nutrients, the review shows that C. glabrata is a specialist that has found alternative strategies to thrive. Understanding these metabolic strategies is important for developing better treatments and fighting antifungal resistance.
