An opportunistic fungal pathogen whose relationship with metals is multifaceted: C. albicans can biosorb heavy metals from its environment, heavy metal exposure promotes its virulence in immunocompromised hosts, and metal nanoparticles are being developed as antifungal …
Candida auris is an emerging multidrug-resistant fungal pathogen first identified in 2009 (Satoh et al. 2009, from a Japanese patient's ear canal) and now classified as a critical-priority pathogen by the WHO (WHO Fungal Priority Pathogens List 2022) and CDC (CDC 2019 A…
A haploid, asexual yeast and the second most common cause of invasive candidiasis after Candida albicans. Recently reclassified into the genus Nakaseomyces (as N. glabratus), though the name C. glabrata remains in widespread clinical use. Unlike C. albicans, C. glabrata…
An encapsulated basidiomycete yeast that causes cryptococcal meningitis -- the leading cause of meningitis in HIV/AIDS patients and responsible for an estimated 180,000 deaths annually. Its nickel-dependent urease has been called the organism's "Achilles' heel" because …
A genus of Gram-positive bacteria (primarily E. faecalis and E. faecium) that exemplifies the metal-antibiotic resistance co-selection crisis. Enterococci carry diverse metal tolerance genes for mercury, arsenic, copper, and cadmium on the same mobile genetic elements a…

The causative agent of tuberculosis (TB), the leading infectious disease killer worldwide (~1.3 million deaths annually). M. tuberculosis has an exceptionally complex metal biology: it deploys nickel-dependent hydrogenase and urease for intracellular survival, species-s…
An opportunistic Gram-negative pathogen with a unique dual-use siderophore system: its pyoverdine and pyochelin serve not only as iron scavengers but as extracellular chelators of toxic metals including nickel, copper, and cadmium. This makes P. aeruginosa unusually wel…
A genus of Gram-positive, facultative anaerobic cocci that includes some of the most clinically significant human pathogens. Staphylococci are defined by their exceptionally comprehensive metal acquisition arsenal -- arguably the most thoroughly characterized of any bac…
A Gram-positive pathogen (the "pneumococcus") that depends on iron, manganese, and zinc for virulence and has evolved dedicated transport systems for each. Iron is required for viability itself, manganese powers the superoxide dismutase needed to survive the oxidative b…
