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 tropicalis is an opportunistic fungal pathogen and occasional gut commensal, increasingly recognized as one of the most clinically significant non-albicans Candida (NAC) species. Once considered a distant runner-up to C. albicans, it has emerged as a major drive…
A genus of Gram-positive obligate anaerobes in the family Lachnospiraceae (Clostridium cluster XIVa) that occupy a critical metabolic relay position in gut ecosystem stability: converting lactate to butyrate. Anaerostipes is one of the most consistently depleted genera …
Structured microbial communities encased in a self-produced extracellular polymeric substance (EPS) matrix. Biofilms are the predominant mode of bacterial and fungal growth in chronic infections, device-associated infections, and the gut. From a metallomics perspective,…
Bipolar disorder is a chronic neuropsychiatric condition characterized by recurrent episodes of mania (or hypomania) and depression, affecting approximately 1-2.4% of the global population. It carries significant morbidity -- reduced life expectancy by 10-15 years, high…
A genus of Gram-positive, strictly anaerobic, butyrate-producing bacteria in the order Clostridiales (phylum Firmicutes). The type species, Butyricicoccus pullicaecorum, was originally isolated from chicken caecal content but has since been identified as a significant m…
Candidozyma auris is the current name for NCBITaxon:498019. Liu and colleagues established the combination in 2024 as MycoBank MB 848169; Candida auris Satoh & Makimura 2009 is its basionym, not a separate species ncbi taxonomy candidozyma auris index fungorum candidozy…
Clostridium butyricum is a spore-forming, obligate anaerobic, Gram-positive bacterium and one of the leading next-generation probiotic candidates. The MIYAIRI 588 strain (CBM 588) is approved as a pharmaceutical probiotic in Japan and has expanding clinical evidence acr…
Colorectal cancer (CRC) is the third most common cancer worldwide and the second leading cause of cancer death. Over 90% of cases are sporadic, driven by a complex interplay between genetic predisposition, dietary habits, gut microbiome composition, and environmental ex…
Debaryomyces is a genus of ascomycetous fungi, with D. hansenii being the most clinically relevant species, that represents a prominent opportunistic pathobiont enriched in inflammatory bowel disease, particularly crohns disease. Unlike many commensal fungi, Debaryomyce…
Functional shielding is the phenomenon in which one microorganism — typically a fungus — physically and immunologically protects a co-resident pathogen from host immune attack, antimicrobial agents, and oxidative stress. The shielding organism's biofilm matrix acts as a…
Gastroesophageal reflux disease (GERD) is a chronic condition in which stomach acid or bile flows back into the esophagus, causing mucosal damage and symptoms such as heartburn and regurgitation. Affecting approximately 20% of Western populations, GERD is conventionally…
HIV (Human Immunodeficiency Virus) causes progressive CD4+ T cell depletion leading to AIDS. In the WikiBiome framework, HIV is notable for the gut-centric model of disease progression: HIV preferentially destroys gut-associated lymphoid tissue (GALT) early in infection…
A genus of Gram-positive, strictly anaerobic bacteria in the family Erysipelotrichaceae (phylum Firmicutes) that is emerging as one of the most consistently protective gut commensals in human disease. Holdemanella is depleted across a striking range of conditions -- inf…
Indole-3-carbinol (I3C) and its metabolite 3,3'-diindolylmethane (DIM) — derived from cruciferous vegetables and also produced by gut bacteria from tryptophan metabolism — as multi-mechanism agents for ovarian cancer. Three independent papers support I3C through distinc…
Microbial communities do not acquire and use metals in isolation. Within biofilms, polymicrobial infections, and the gut microbiome, microbes engage in complex cooperative and competitive relationships mediated by metals -- sharing metallophores, concentrating metals in…
Lodderomyces elongisporus is an ascomycetous yeast and the closest known phylogenetic relative of Candida parapsilosis. Originally considered non-pathogenic, it has emerged as a rare but clinically significant cause of fungemia, particularly in patients with indwelling …
Microbiome-derived metabolites are small molecules made, consumed, or chemically transformed through activity in the gut microbiome and other host-associated communities. They connect community function to host biology, but the phrase covers several kinds of provenance:…
Mortierella is a genus of soil-dwelling fungi in the phylum Mortierellomycota (formerly placed in Zygomycota). While primarily known as environmental saprotrophs, Mortierella species have recently been identified as residents of the human gut mycobiome -- the fungal com…
Multiple sclerosis (MS) is a chronic autoimmune demyelinating disease of the central nervous system, with a global prevalence of approximately 2.8 million attfield 2022 immunology ms nature review. The conventional framing centers on genetic susceptibility (HLA-DRB115:0…
The fungal component of the human microbiome, comprising ~0.1-1% of the total gut microbial community by abundance but disproportionately active in immune signaling and cross-kingdom interactions. While bacterial communities dominate microbiome research, emerging eviden…
N-glycosylation is a post-translational modification in which glycan chains are attached to asparagine residues on proteins. This modification is critical for protein folding, cell-cell recognition, and immune system signaling. In the context of host-microbe interaction…
Nakaseomyces glabratus is the current name for NCBITaxon:5478. Takashima and Sugita established the current combination in 2022 as MycoBank MB 843854; Candida glabrata is a homotypic synonym and former combination, while Cryptococcus glabratus H.W. Anderson 1917 is the …
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…
Pancreatitis is inflammation of the pancreas, occurring in acute (AP) and chronic (CP) forms. Acute pancreatitis ranges from mild self-limiting disease to severe necrotizing pancreatitis with 20-30% mortality. Chronic pancreatitis is a risk factor for pancreatic cancer …
