Age‐Associated Gut Microbiota Dysbiosis Impairs Antiviral Defense During Influenza Virus Infection and Identifies Acetate as a Protective Mediator in Senescent Human Lung Cells

Aging Cell, Volume 25, Issue 10, October 2026.
Aging altered the gut microbiota, reduced short‐chain fatty acid (SCFA) potential, and worsened influenza A virus (IAV)‐associated dysbiosis. In senescent human lung fibroblasts, acetate reduced IAV replication and inflammation via GPR41/43 signaling and histone acetylation, suggesting that SCFAs help protect antiviral defense along the gut–lung axis ...

Longitudinal Follow‐Up of Gut and Salivary Microbiota in Children With Food Protein‐Induced Enterocolitis Syndrome

Allergy, Volume 81, Issue 10, Page 3608-3619, October 2026.
This study aimed to compare both the gut and salivary microbiota over time between allergic and tolerant patients and matched controls. Allergic patients with food protein‐induced enterocolitis syndrome exhibited lower gut and salivary alpha‐diversities, several genus‐level differences, and higher acetate levels than controls.

Complete genome sequences of Cytobacillus sp., Domibacillus sp., Enterobacter sp., Neisseria sp., Pseudomonas sp., and Streptococcus sp. strains from human clinical infections collected at diagnostic units in 2020

Members of Bacillota and Pseudomonadota phyla are frequently considered bacterial infectious agents in humans. As part of a large sequencing project of clinically relevant pathogens, we hybrid-assembled complete genomes of Cytobacillus, Domibacillus ...

Tannic acid shaped microbiome composition in midguts and rearing microcosms of Aedes triseriatus (Say)

Frontiers in Microbiology
IntroductionTannic acid (TA), a polyphenol derived from plants, often accumulates in water-holding containers where mosquitoes develop. Yet, its effects on mosquito gut microbiota remain poorly understood, representing an important knowledge gap. Because

Microbiota Signatures in Early Life and Their Association With Food Allergy: A Systematic Review

Allergy, Volume 81, Issue 10, Page 3453-3471, October 2026.
ABSTRACT Food allergy (FA) is increasing worldwide, and early life may be a critical window for immune training. We systematically reviewed observational human studies linking early‐life microbiota (infant, maternal, environmental, or extraintestinal) profiled using culture‐based and/or culture‐independent methods (including sequencing‐based approaches)

Analyse bioinformatique de l'évolution de la phototrophie chez un clade bactérien : les Pseudomonadota

International audiencePhototrophy is an ancient bacterial metabolism that likely originated over 3 billion years ago, prior to the rise of atmospheric oxygen provoked by oxygenic photosynthesis of Cyanobacteriia.

Inter-phylum circulation of a beta-lactamase-encoding gene: a rare but observable event.

Beta-lactamase-mediated degradation of beta-lactams is the most common mechanism of beta-lactam resistance in Gram-negative bacteria. Beta-lactamase-encoding genes can be transferred between closely related bacteria, but spontaneous inter-phylum ...

The chromosomal genome sequence of a demosponge, Phyllospongia foliascens (Pallas, 1766) (Dictyoceratida: Thorectidae) and its associated microbial metagenome sequences

We present a genome assembly from a specimen of Phyllospongia foliascens (Porifera; Demospongiae; Dictyoceratida; Thorectidae). The genome sequence has a total length of 402.95 megabases.

Distinct Microbiota and Functional Pathway Profiles Define Success and Failure in Regenerative Endodontic Treatment

International Endodontic Journal, Volume 59, Issue 10, Page 2223-2237, October 2026.
ABSTRACT Aim To characterize the intracanal microbiota and identify key microbial taxa and functional pathways associated with regenerative endodontic treatment (RET) outcomes. Methodology In this observational cohort study, 196 samples were collected at five time points from external tooth surfaces (T1, T4) and root canals (T2, T3, T5).

The mediating role of genes in the influence of intestinal flora on type 2 diabetes and the screening of diagnostic markers

Journal of Diabetes Investigation, Volume 17, Issue 10, Page 1816-1834, October 2026.
Using Mendelian randomization, TWAS/eQTL analysis, machine learning, and single‐cell RNA sequencing, this study identified gut microbiota taxa causally linked to type 2 diabetes, candidate mediator genes, and diagnostic markers (BEND7, BLVRA, C1orf85, and LAMC1).
