Multiple tissue transcriptomic responses to Piscirickettsia salmonis in Atlantic salmon (Salmo salar)

, 2011
The bacterium Piscirickettsia salmonis is the etiological agent of salmonid rickettsial septicemia (SRS), a severe disease that causes major economic losses to the Atlantic salmon aquaculture industry every year.

Flagellins as Vaccine Adjuvants and Cancer Immunotherapy: Recent Advances and Future Prospects

Immunology, Volume 176, Issue 3, Page 277-303, November 2025.
The figure depicts the role of flagellin in immune cells. Flagellin interacts with TLR5, resulting in the formation of homodimers and the recruitment of MyD88, which activates the IκB and MAPK signalling pathways. This results in the activation of NF‐κB and AP‐1, producing TNF‐α, IL‐6, IL‐8, and IL‐12.

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

Phenotypic and genetic characterization of Piscirickettsia salmonis from Chilean and Canadian salmonids [PDF]

BMC Veterinary Research, 2016
The study presents the phenotypic and genetic characterization of selected P. salmonis isolates from Atlantic salmon and rainbow trout suffering from SRS (salmonid rickettsial septicemia) in Chile and in Canada. The phenotypic characterization of the P. salmonis isolates were based on growth on different agar media (including a newly developed medium),

Revisiting Vitamin and Trace Mineral Nutrition in Atlantic Salmon Farming With Emphasis on Fish Health

Reviews in Aquaculture, Volume 17, Issue 4, September 2025.
ABSTRACT Atlantic salmon farming is faced with numerous environmental and production‐related challenges affecting fish health and welfare, globally and in Norway. An animal's requirement for a nutrient is the sum of the required supply of available nutrients for maintenance, growth, reproduction, health, and disease resistance.

Phylogenetic Diversity and Geographic Distribution of Atlantic Salmon Calicivirus in Major Salmon Farming Regions

Journal of Fish Diseases, Volume 48, Issue 6, June 2025.
ABSTRACT Salovirus is a genus within the family Caliciviridae, which contains a single member species, Salovirus nordlandense, also known as Atlantic salmon calicivirus (ASCV). While previous work has shown that ASCV can replicate in fish cell lines and establish systemic infection in vivo, its exact role in disease remains unclear and very little is ...

Application of Conservation Genomics to Investigate the Role of Pathogens on the Migration of Sea‐Run Brown Trout (Salmo trutta)

Journal of Fish Diseases, Volume 48, Issue 5, May 2025.
ABSTRACT Pathogens play a key role in individual function and the dynamics of wild populations, but the link between pathogens and individual performance has rarely been investigated in the wild. Migrating salmonids offer an ideal study system to investigate how infection with pathogens affects performance given that climate change and fish farming ...
