Ecological Processes Shaping Marine Microbial Assemblages Diverge Between Equatorial and Temperate Time‐Series

Molecular Ecology, Volume 35, Issue 2, January 2026.
ABSTRACT Marine microbial communities are structured by a complex interplay of deterministic and stochastic processes, yet how these vary across latitudes remains poorly understood. Most long‐term microbial observatories are restricted to temperate regions, limiting our ability to assess latitudinal contrasts in microbial dynamics.

Global Warming Affects the Pathogenesis of Important Fish Diseases in European Aquaculture

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
The effect of global warming on pathogens and their fish hosts that could exacerbate the negative outcomes for aquaculture. Changes in farming practices and the development of innovative mitigation tools may prove essential to cope with the effects and impacts of rising water temperatures on fish diseases in Europe.

Phage‐Host Interactions in Flavobacterium Pathogens and the Potential of Phage‐Based Disease Control in Salmonid Aquaculture

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT A major bottleneck to the projected expansion of the aquaculture industry is disease outbreaks caused by bacterial pathogens. Fish diseases caused by Flavobacterium pathogens are persistent in salmonid aquaculture, and treatment is limited to antimicrobials, which contaminate the aquatic environment and promote antimicrobial resistance ...

The microbiota of moon snail egg collars is shaped by host-specific factors

Microbiology Spectrum
Moon snails (Family: Naticidae) lay eggs using a mixture of mucus and sediment to form an egg mass commonly referred to as an egg collar. These egg collars do not appear to experience micro-biofouling or predation, and this observation led us to ...

Growth Performance and Intestinal Health of Triploid Rainbow Trout (Oncorhynchus mykiss) Through Bile Acid Supplementation in Low Fishmeal Diets: Insights From Metabolomics, Microbiota, and Gene Expression

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
This research aimed to explore the impact of bile acid (BA) supplementation in low fishmeal diets on growth performance, serum biochemical indices, tissue morphology, lipid metabolism, gene expression, and gut microbiota in triploid rainbow trout (Oncorhynchus mykiss, initial weight 15.97 ± 1.4 g).

Identification of a Pair of Linear or Cyclic Naturally Inspired Bifunctional Lipopeptide Antibiotics That Overcome Antimicrobial Resistance

Advanced Science, Volume 12, Issue 45, December 4, 2025.
The underexplored bacterial genus Aquimarina harbors a large biosynthetic potential for discovering new antibiotics. Here, the authors identify a pair of linear or cyclic bifunctional cationic lipopeptide antibiotics, aquicidine L and C4, inspired by the aquicidine gene cluster from Aquimarina.

Amoebic Gill Disease (AGD) in Atlantic Salmon Investigated Through a Holo‐Omic Lens

Ecology and Evolution, Volume 15, Issue 11, November 2025.
In this exploratory study, we integrated 16S rRNA profiling with quantitative genetics to examine the gill microbiota of Atlantic salmon during infection with Neoparamoeba perurans, the causative agent of amoebic gill disease (AGD), treating the microbiota as an extended resistance trait.

Changes in the Structure of the Bacterial Community Associated With Ericaria amentacea Blades Under Disturbed Conditions

Plant-Environment Interactions, Volume 6, Issue 5, October 2025.
ABSTRACT The macroalgae of the Cystoseira sensu lato complex host a great epiphytic bacterial community that significantly guarantees several important physiological processes, especially in case of disturbance. However, no direct evidence of relevant changes in the quali‐quantitative composition of these communities under anthropic disturbance is ...

Bacterial 16S Ribosomal Gene Fingerprints as a Tool to Diagnose and Mitigate Fish Larvae Gut Dysbiosis

Environmental Microbiology Reports, Volume 17, Issue 5, October 2025.
This study profiles the gut microbiota of poor‐ and good‐quality seabream and seabass larvae across different sites using 16S rRNA sequencing. Several bacterial markers associated with larval quality were identified and used to develop a dysbiosis index. Gut bacterial correlation networks revealed potential bacteria–bacteria interactions.
