The Factors Involved in Plant–Insect–Microbe Interactions Expanded: Genome Analysis and Description of Frigoribacterium adelgis sp. nov.

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Aerobic Actinobacteria belonging to the genus Frigoribacterium were isolated from adelgid Adelges (Aphrastasia) pectinatae collected from a Korean fir tree. Genomic analysis showed that these bacteria encode a range of factors that may be involved in the interactions between Frigoribacterium strains, adelgids and/or Korean fir trees.

Caractérisation du système d’acquisition de fer codé par le locus iro chez Salmonella enterica sérovar Typhi

, 2013
Le fer est un élément essentiel pour les bactéries. Puisqu’elles ne peuvent le synthétiser elles-mêmes, elles utilisent un ou plusieurs systèmes d’acquisition de fer afin de se le procurer dans l’environnement, ou chez l’hôte pour leurs propres ...

Quorum sensing controls the production of the siderophore malleobactin in Burkholderia thailandensis E264 [PDF]

, 2019
Siderophores are chelating molecules with a very high affinity for Fe3+, an essential element for the survival of most living organisms. These molecules are produced and secreted by bacteria under iron-limiting conditions.

Conjugative Transfer of Disease‐Encoding Plasmid Variants in Serratia spp. Alter Production of Enzymes and Virulence Properties

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Analysis of plasmid transconjugants relative to plasmid‐free and plasmid‐carrying Serratia spp. demonstrates erratic disease phenotypes and reduced fitness. Transconjugants also show reduced ability to degrade substrates associated with virulence, supported by transcriptomic data.

Le facteur de transcription Fep1 interagit avec Tup11, un corépresseur de la famille des protéines à motifs WD40 [PDF]

, 2004
De part sa propriété à acquérir et à céder les électrons, le fer constitue un élément incontournable dans divers sentiers métaboliques. Son potentiel rédox flexible est exploité par une variété de protéines qui lient l'oxygène ou qui transfèrent les ...

The Role of the Gut Microbiome in the Complex Network of Frailty Syndrome and Associated Comorbidities in Aging

Aging Cell, Volume 25, Issue 2, February 2026.
This study analyzed gut microbiota in older adults with and without Frailty Syndrome by 16S rRNA gene sequencing and metagenomics. Frailty was associated with altered microbial composition, metabolic functions, and increased antimicrobial resistance, whereas non‐frail individuals showed healthier profiles.

Fraternal cooperation of hierarchical cancer parallels metazoan multicellularity and eusociality

Biological Reviews, Volume 101, Issue 1, Page 400-418, February 2026.
ABSTRACT Metazoan multicellularity and eusociality — both outcomes of the fraternal major transitions — have numerous features in common such as uneven distribution of group‐establishing potential. In addition to this framework, I argue herein that the group‐forming principles of metazoan multicellularity and eusociality are analogous to hierarchical ...

Isolation, identification, and pathogenic potential of Bacillus cereus from diseased big‐belly seahorse Hippocampus abdominalis

Journal of the World Aquaculture Society, Volume 57, Issue 1, February 2026.
Abstract Members of Bacillus cereus have been documented as important bacterial pathogens in aquaculture. However, scarce information is available on B. cereus isolates as causal pathogens of big‐belly seahorses Hippocampus abdominalis. In the present study, a B. cereus isolate (SH1), recovered from a disease outbreak on a seahorse farm, was identified
