A Gram-negative, obligate anaerobic, mucin-degrading bacterium that colonizes the intestinal mucus layer and has emerged as one of the most important next-generation probiotics. A. muciniphila is consistently depleted in disease states associated with metal dyshomeostas…
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 …
Christensenellaceae is a family of Gram-negative, strictly anaerobic bacteria within the order Clostridiales (phylum Firmicutes) that has emerged as one of the most consistently health-associated and heritable members of the human gut microbiome. First formally describe…
A genus of Gram-positive, obligate anaerobic bacteria within the Actinobacteria phylum (family Coriobacteriaceae) that has emerged as a consistent pathobiont enriched in cardiometabolic and autoimmune diseases. C. aerofaciens is the most studied species, with establishe…
A Gram-positive, obligate anaerobic genus within the lachnospiraceae family (Firmicutes phylum). Coprococcus is one of the most important butyrate-producing commensals in the human gut and has gained particular attention as the "happiness bug" -- one of very few taxa di…
Firmicutes (recently reclassified as Bacillota) is the dominant bacterial phylum in the Western adult gut, comprising the core community of short-chain fatty acid (SCFA) producers that maintain intestinal barrier integrity, regulate immune function, and influence system…
A genus of Gram-positive, facultatively anaerobic lactic acid bacteria (LAB) that are among the most extensively studied probiotics. In the metallomics context, Lactobacillus species are critical for two reasons: they actively detoxify heavy metals through binding and s…
Oscillibacter is a genus of Gram-negative, strictly anaerobic, motile bacteria within the family Oscillospiraceae (phylum Firmicutes). The type species, Oscillibacter valericigenes, was first isolated from the alimentary canal of a Japanese corbicula clam and named for …
A family of Gram-positive obligate anaerobes (formerly classified as the genus Oscillospira, now reclassified into Oscillibacter and related genera within Oscillospiraceae) that serve as keystone butyrate producers in the healthy human distal colonic microbiota (Konikof…
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 versatile Gram-positive pathogen with one of the best-characterized nutritional immunity evasion systems known. S. aureus requires nickel, iron, zinc, and manganese for virulence and has evolved dedicated acquisition systems for each, including the novel metallophore …
