A Postbiotic‐Inducing Ganoderma applanatum Polysaccharide Repairs the Intestinal Barrier via a Phocaeicola vulgatus ‐ Tridecylic Acid Axis

Advanced Science, EarlyView.
This study identifies GAP2, a bioactive polysaccharide fraction derived from Ganoderma applanatum, as a postbiotic inducer that repairs intestinal barrier damage in a gut microbiota‐dependent manner. GAP2 enriches Phocaeicola vulgatus, which degrades GAP2 and promotes tridecylic acid production, triggering Rho/CDC42 signaling and tight‐junction ...

Modulation of Animal Gut Health by Milk Oligosaccharide

Animal Research and One Health, EarlyView.
This review summarizes the composition and structural characteristics of MOs across different mammalian species, and elucidates their roles and mechanisms in maintaining intestinal homeostasis by regulating gut microbiome and enhancing intestinal chemical, physical and immune barriers.

Transfection of the Anaerobe Bacteroides thetaiotaomicron with Phage DNA [PDF]

Journal of General Microbiology, 1977
SUMMARY: The properties of a Bacteroides thetaiotaomicron phage, β1, are described. Phenol-extracted phage β1 DNA transfects Ca2+-treated B. thetaiotaomicron cells and transfection is not limited to a particular stage in the growth cycle. An obligatory step in the transfection procedure is a 33-fold dilution in broth, allowing replication of the ...

Dietary Artificial Sweeteners: From Chemical Transformation in Food to Gut Microbial Processing

ChemFoodChem, EarlyView.
This review article unites classical and recent findings on the stability of artificial sweeteners in food. The focus is on ten sweeteners approved in the European Union: their chemical stability during processing and storage, individual degradation products, and their interactions with the intestinal microbiota.

Effects of Glyphosate and Glyphosate‐Based Herbicides on the Mammalian Gut Microbiome: A Critical Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Glyphosate has long been considered to pose negligible direct risk to mammals on the grounds that its molecular target, 5‐enolpyruvylshikimate‐3‐phosphate synthase (EPSPS), of the shikimate pathway, is absent from animal cells. This rationale is inaccurate as a complete toxicological argument, because the shikimate pathway is present in some ...

Growth of succinate consumer Dialister hominis is supported by Bacteroides thetaiotaomicron

Anaerobe, 2022
This study revealed an interaction between the gut commensal bacterium Bacteroides thetaiotaomicron JCM 5827T and asaccharolytic bacterium Dialister hominis JCM 33369T, which uses succinate instead of carbohydrates for growth. D. hominis usually forms extremely small colonies on Brucella blood agar plates.

Reframing the Gut–Brain Axis: The Gut Wall as a Neural Immune Interface in Multiple Sclerosis and Autoimmune Neurological Diseases

Annals of Neurology, Volume 100, Issue 5, Page 915-930, November 2026.
Gut wall physiology in multiple sclerosis (MS) and autoimmune neurologic diseases remains underexplored but may span gut barrier dysfunction, enteric glial targeting, mucosal immune dysregulation, and autoimmune targets within the enteric nervous system (ENS).
