The virome is the collection of all viruses inhabiting a given ecosystem -- in the gut, this means primarily bacteriophages (phages), which constitute ~90% of the intestinal virome. While microbiome research has historically focused on bacteria, mounting evidence shows …
Viruses that exclusively infect bacteria. Bacteriophages -- phages for short -- are the most abundant biological entities on Earth, outnumbering bacteria in most environments by ratios of 1:1 to 10:1. In the human gut, the phageome represents a powerful but underexplore…
Bacteroidaceae is a family of obligate anaerobic, Gram-negative bacteria in the order bacteroidales. The dominant genus is bacteroides, which includes B. fragilis, B. vulgatus, B. thetaiotaomicron, and B. uniformis. Bacteroidaceae are among the most abundant gut bacteri…
Bifidobacteriaceae is the family containing bifidobacterium and related genera (alloscardovia). It is the dominant family in the healthy infant gut and a significant commensal family in adults. Family-level depletion is documented in ASD (marked reduction of Actinobacte…
Clostridium symbiosum is a Gram-positive, obligately anaerobic bacterium within the Clostridium cluster XIVa — a taxonomic group enriched for short-chain fatty acid (SCFA) producers and specialized bile acid metabolizers. Despite its ambiguous name (suggesting symbiotic…
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…
Hepatitis (liver inflammation) encompasses viral (HBV, HCV, HAV), autoimmune, alcoholic, and toxin-induced forms. In the WikiBiome framework, the gut-liver axis is central — portal blood delivers gut-derived microbial products (LPS, bacterial DNA) directly to the liver …
Immunotherapy harnesses the patient's own immune system to fight disease, most notably cancer. Immune checkpoint inhibitors (ICIs) -- antibodies that block PD-1, PD-L1, or CTLA-4 -- have revolutionized oncology since their introduction in the 2010s, producing durable re…
Necrotizing enterocolitis (NEC) is the most common and lethal gastrointestinal emergency in premature infants, affecting 5-12% of very low birth weight neonates (<1500 g) with mortality rates of 20-30%. Characterized by intestinal inflammation, necrosis, and perforation…
Pancreatic cancer is the fifth leading cause of cancer death in Western nations, with rising incidence globally. Pancreatic ductal adenocarcinoma (PDAC) accounts for over 90% of cases. Five-year survival remains approximately 12%, owing to late-stage diagnosis, aggressi…
Phage therapy uses bacteriophages — viruses that infect and lyse specific bacteria — as precision antimicrobials. Unlike broad-spectrum antibiotics, phages target specific bacterial species or strains, sparing the commensal microbiome. In the WikiBiome framework, phage …
Psoriasis is a chronic, immune-mediated inflammatory skin disease characterized by keratinocyte hyperproliferation, resulting in well-demarcated erythematous plaques with silvery scales. Affecting approximately 2-3% of the global population, psoriasis is now understood …
A filamentous fungus in the order Hypocreales (family Ophiocordycipitaceae), historically studied as an insect and nematode pathogen (P. lilacinum, formerly Paecilomyces lilacinus), now emerging as a clinically significant protective member of the gut mycobiome — and it…
A severe neuropsychiatric disorder affecting approximately 1% of the global population, characterized by positive symptoms (hallucinations, delusions), negative symptoms (anhedonia, social withdrawal, flat affect), and cognitive deficits. Life expectancy is reduced by 1…
This page serves as a redirect and cross-reference point for the comprehensive virome concept page, which covers the gut virome, bacteriophage-bacteria interactions, phage therapy, and virome-disease associations in detail. The term viral microbiota emphasizes that viru…
