Structural basis of mammalian high-mannose N-glycan processing by human gut Bacteroides

Nature Communications, 2020
Human gut bacteria depolymerize glycans into their sugar components, which otherwise cannot be processed by their host. Here, the authors characterise the endo-β-N-acetylglucosaminidase EndoBT-3987 from the Gram-negative symbiont Bacteroides ...

When two diseases collide: Endometriosis as a risk factor for severe pelvic inflammatory disease

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Endometriosis is associated with a more severe clinical course of pelvic inflammatory disease in hospitalized patients, including higher rates of antibiotic treatment failure, longer hospital stay, and increased need for surgical intervention. Abstract Introduction Our objective was to compare the severity of pelvic inflammatory disease (PID) in ...

Distinct effects of different Bacteroides strains on depressive-like behavior via a gut-Th1/Th17 cells-brain axis

Communications Biology
Extensive evidence links gut microbiota to the pathogenesis of major depressive disorder (MDD), yet the specific microbial species involved remain unclear. Here, we identify distinct roles of three Bacteroides species—B. uniformis, B.

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

FEBS Open Bio, Volume 16, Issue 8, Page 1537-1549, August 2026.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

The Role of the Gut Microbiota in Allogeneic Hematopoietic Cell Transplantation

American Journal of Hematology, Volume 101, Issue 8, Page 1980-1996, August 2026.
ABSTRACT Allogeneic hematopoietic cell transplantation (allo‐HCT) is an effective treatment for patients with high‐risk hematologic malignancies. Over the last decade, gut microbiota composition during allo‐HCT has been associated with patients' outcomes.

PCR Assay for Species-Specific Identification of Bacteroides thetaiotaomicron [PDF]

Journal of Clinical Microbiology, 2000
ABSTRACT Bacteroides thetaiotaomicron is the second most frequently encountered species of the anaerobes isolated from clinical specimens. We developed a PCR-based assay for the rapid identification of B. thetaiotaomicron .

Seasonal Restructuring of Microbial Communities and Resistomes in the Shitalakshya River, Bangladesh Revealed by Shotgun Metagenomics

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Dry‐season pollutant concentration drives microbial restructuring in Bangladesh's Shitalakshya River, shifting communities from Myroides to stress‐tolerant genera while enriching metal resistance genes and efflux pumps, revealing non‐antibiotic co‐selection as a key driver of antimicrobial resistance in urban waters.

Crystal structure of endo‐β‐1,6‐galactanase from Streptomyces avermitilis

Acta Crystallographica Section D, Volume 82, Issue 8, Page 962-971, August 2026.
The crystal structure of S. avermitilis endo‐β‐1,6‐galactanase belonging to GH30 subfamily 5 reveals the first structural framework for endo‐β‐1,6‐galactanase. The β‐1,6‐galactobiose‐bound complex identifies the catalytic subsites and a distal secondary sugar‐binding site, providing insight into β‐1,6‐galactan recognition.Endo‐β‐1,6‐galactanases ...

Apiotrichum‐Centered Fungal Interaction Network Disturbance Correlates With Increased Arterial Stiffness

Aging Cell, Volume 25, Issue 8, August 2026.
Apiotrichum‐centered gut fungal network disturbance correlates with increased arterial stiffness. Five driver genera including Apiotrichum, Mycothermus, Flavocillium, Hyaloscypha, and Microscypha regulate the interaction shift. Thirty‐nine metabolites comprising organic acids, fatty acyls, and sucrose target vasoconstriction regulators CYP11B2, ROCK2 ...
