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 ...

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.

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 ...

A review of bacterial disease outbreaks in rainbow trout (Oncorhynchus mykiss) reported from 2010 to 2022

Journal of Fish Diseases, Volume 48, Issue 9, September 2025.
Abstract Outbreaks of bacterial infections in aquaculture have emerged as significant threats to the sustainable production of rainbow trout (Oncorhynchus mykiss) worldwide. Understanding the dynamics of these outbreaks and the bacteria involved is crucial for implementing effective management strategies. This comprehensive review presents an update on

Antimicrobial susceptibility of Flavobacterium psychrophilum isolates from the United Kingdom [PDF]

Journal of Fish Diseases, 2017
AbstractRoutine application of antimicrobials is the current treatment of choice for rainbow trout fry syndrome (RTFS) or bacterial coldwater disease (BCWD) caused by Flavobacterium psychrophilum. In this study, the antimicrobial susceptibilities of 133 F.

Efficacy of a polyvalent immersion vaccine against Flavobacterium psychrophilum and evaluation of immune response to vaccination in rainbow trout fry (Onchorynchus mykiss L.)

Veterinary Research, 2017
Rainbow trout fry syndrome (RTFS) is a disease caused by the Gram-negative bacterium Flavobacterium psychrophilum, responsible for significant economic losses in salmonid aquaculture worldwide. The diversity of F.

Reliability of PCR Methods for the Detection of Flavobacterium psychrophilum

Fish Pathology, 2008
We compared the sensitivity and specificity of PCR methods targeting 16S rDNA, DNA gyrase subunit genes (gyrA, gyrB) and peptidyl-prolyl cis-trans isomerase C gene (ppiC) for the detection of Flavobacterium psychrophilum using 82 bacterial isolates and 55 washings of fish gills. To identify F.
