Expanding Horizons in Phage Therapy: Addressing Antibiotic Resistance in Aquaculture

Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT Aquaculture has emerged as a cornerstone of global food security, yet its rapid intensification has precipitated widespread bacterial disease outbreaks and escalating antimicrobial resistance (AMR). This review critically examines the limitations of conventional antibiotic use in aquaculture, highlighting regulatory inconsistencies ...

Bacterial coldwater disease of fishes caused by Flavobacterium psychrophilum

Journal of Advanced Research, 2011
Coldwater disease (CWD) is a bacterial disease that affects a broad host-species range of fishes that inhabit cold, fresh waters. This disease occurs predominately at water temperatures of 16 °C and below, and is most prevalent and severe at 10 °C and ...

Changes in the Cell Structure of Flavobacterium psychrophilum with Length of Culture [PDF]

Microbiology and Immunology, 2001
AbstractFlavobacterium psychrophilum, the pathogen of bacterial cold‐water disease, causes serious problems in ayu Plecoglossus altivelis culture. This study investigated the effect of the culture period of F. psychrophilum and on the structure of its cells.

OmpA_C‐Like Domain of PorE Is Essential for PorE Function in the Type IX Secretion System (T9SS) of Porphyromonas gingivalis and Some T9SS Cargo Proteins Are Secreted in a PorE‐Independent Manner

Microbiology and Immunology, Volume 70, Issue 1, Page 15-26, January 2026.
ABSTRACT The periodontal pathogen Porphyromonas gingivalis secretes gingipains, highly hydrolytic proteases, to the cell surface or external environment via a type IX secretion system (T9SS). PorE is one of the T9SS component proteins essential for gingipain secretion. It consists of four domains: TPR, WD40, CRD, and OmpA_C‐like.

Metabarcoding Reveals a Potentially Undescribed Columnaris‐Causing Bacterium in Peracute Skin Disease of Rainbow Trout (Oncorhynchus mykiss, Walbaum)

Journal of Fish Diseases, Volume 49, Issue 1, January 2026.
ABSTRACT Columnaris‐causing bacteria (CCB) represent a group of four Flavobacterium species, previously classified under Flavobacterium columnaris, causing a threatening condition in salmonid farming characterised by cutaneous and gill lesions, commonly referred to as ‘saddleback disease’. A peracute skin disease outbreak with high mortality in rainbow

Flavobacterium psychrophilum, invasion into and shedding by rainbow trout Oncorhynchus mykiss [PDF]

Diseases of Aquatic Organisms, 2000
The infection route of Flavobacterium psychrophilum into rainbow trout Oncorhynchus mykiss was studied using bath and cohabitation challenges as well as oral challenge with live feed as a vector. Additionally, the number of bacterial cells shed by infected fish into the surrounding water was determined in the cohabitation experiment and in challenge ...

PACAP Is Lethal to Flavobacterium psychrophilum Through Either Direct Membrane Permeabilization or Indirectly, by Priming the Immune Response in Rainbow Trout Macrophages

Frontiers in Immunology, 2019
Pituitary adenylate cyclase-activating polypeptide (PACAP) is a multifunctional neuropeptide that is widely distributed in mammals and is capable of performing roles as a neurotransmitter, neuromodulator, and vasodilator.

Stress Nutrition in Aquatic Animals: From Definition to Practice

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Aquaculture faces numerous challenges, with stress being one of the major issues that lead to growth loss, metabolic disorders, weakened immunity, redox imbalance, and organ damage in aquatic animals. Nutritional intervention is one of the effective strategies to address these problems. Traditional research has primarily focused on the impacts

Neutrophil Migration in the Activation of the Innate Immune Response to Different Flavobacterium psychrophilum Vaccines in Zebrafish (Danio rerio)

Journal of Immunology Research, 2015
Flavobacterium psychrophilum is a Gram-negative bacterium, responsible for the bacterial cold-water disease and the rainbow trout fry syndrome in freshwater salmonid fish. At present, there is only one commercial vaccine in Chile, made with two Chilean F.

Aquaculture Reuse Water, Genetic Line, and Vaccination Affect Rainbow Trout (Oncorhynchus mykiss) Disease Susceptibility and Infection Dynamics

Frontiers in Immunology, 2021
Infectious hematopoietic necrosis virus (IHNV) and Flavobacterium psychrophilum are major pathogens of farmed rainbow trout. Improved control strategies are desired but the influence of on-farm environmental factors that lead to disease outbreaks remain ...
