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 ...

Potential mechanisms of attenuation for rifampicin-passaged strains of Flavobacterium psychrophilum [PDF]

BMC Microbiology, 2015
Flavobacterium psychrophilum is the etiologic agent of bacterial coldwater disease in salmonids. Earlier research showed that a rifampicin-passaged strain of F. psychrophilum (CSF 259-93B.17) caused no disease in rainbow trout (Oncorhynchus mykiss, Walbaum) while inducing a protective immune response against challenge with the virulent CSF 259-93 ...

Effects of Flavobacterium psychrophilum extracellular products and lipopolysaccharide antigens on the antioxidant enzyme system activity of rainbow trout (Oncorhynchus mykiss) fry

Macedonian Journal of Chemistry and Chemical Engineering, 2022
The aim of this study was to investigate the response of different doses of lipopolysaccharide (LPS) and extracellular product (ECP) antigens (25, 50, 100, 250, and 500 µg) obtained from Flavobacterium psychrophilum to changes in oxidative stress ...

Decreased resistance to bacterial cold-water disease and excessive inflammatory response in ayu (Plecoglossus altivelis) reared at high water temperature

Frontiers in Immunology, 2023
IntroductionTemporal elevation of water temperature positively affects immune activity and disease resistance in poikilothermic teleost fish. The ayu, Plecoglossus altivelis, an important fish species for Japanese freshwater fisheries, is usually ...

Functional Feeds as Immunostimulants for Aquaculture: A Molecular Perspective

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
The development of aquafeeds that enhance immunity in fish represents an effective strategy for disease management in aquaculture. This approach involves incorporating functional ingredients with immunostimulatory properties to improve fish welfare.

An Investigation on the Distribution of Flavobacterium psychrophilum in the Umikawa River.

Fish Pathology, 2000
1999年5月から12月に新潟県海川で天然遡上アユ, 標識放流したアユ種苗, 流下アユ仔魚および他の生息魚を採集して F.psychrophilum の検出を試みた。 IFAT または nested PCR により検査した結果, 放流前のアユ種苗の一部, 採集された全てのグループのアユと他の4魚種（ヤマメ, ウグイ, ウキゴリ, ヨシノボリ）および成熟アユの卵から本菌が検出され, また, 河床の微細藻類や河川水の一部が PCR 陽性を示した。 これらの結果から親魚から仔魚への冷水病菌の伝播, 放流魚や他魚種等から天然遡上アユへの伝播の可能性が示された。

Starvation of Flavobacterium psychrophilum in broth, stream water and distilled water [PDF]

Diseases of Aquatic Organisms, 2003
Physical changes in Flavobacterium psychrophilum, the causative agent of rainbow trout fry syndrome (RTFS), were examined over a 19 wk period of starvation. Bacteria were maintained in either Cytophaga broth, filtered stream water, or filtered distilled water, or were maintained in broth after disinfection as a negative control for dead bacteria ...

Serum Biomarkers in Atlantic Salmon for Differential Diagnosis of Cardiomyopathy Syndrome and Pancreas Disease: Proteomic Identification of Serum Fibrinogen to Enhance Troponin Immunoassay as Optimal Diagnostic Approach

Journal of Fish Diseases, Volume 48, Issue 11, November 2025.
ABSTRACT Cardiac viral diseases are among the major causes of economic losses in Atlantic salmon (Salmo salar L.) aquaculture. These include cardiomyopathy syndrome (CMS) caused by piscine myocarditis virus (PMCV) and pancreas disease (PD) caused by Atlantic salmonid alphavirus (SAV).

Outer Membrane Vesicles From Bacteroides fragilis Contain Coding and Non‐Coding Small RNA Species That Modulate Inflammatory Signalling in Intestinal Epithelial Cells

Journal of Extracellular Biology, Volume 4, Issue 10, October 2025.
Outer membrane vesicles (OMVs) from Bacteroides fragilis carry distinct coding and non‐coding RNAs that influence host inflammatory signaling. Extravesicular RNAs from OMVs suppress IL‐8 expression in intestinal epithelial cells, while removal of these RNAs enhances pro‐inflammatory IL‐8 responses.
