Viral Pathogens Threatening Cage‐Cultured Nile Tilapia in Lake Victoria: Epidemiology, Emerging Risks and Integrated Health Management Strategies

Aquaculture, Fish and Fisheries
The rapid expansion of cage culture for Nile tilapia (Oreochromis niloticus) in Lake Victoria is central to food security and profitable development in East Africa. Nevertheless, viral conditions affect the sustainability of this sector, with significant

Mortality in Salmon (Salmo salar) Fry Related to Lipoid Liver Disease Induced by Unbalanced Fatty Acid Composition of the Diet

Journal of Fish Diseases, EarlyView.
ABSTRACT In 2023, all but one Swedish restocking farm rearing Baltic salmon and sea trout fry experienced massive mortality caused by lipoid liver disease (LLD). The struck farms used the same feed, and this was suspected to be the cause of the outbreak.

Investigating the mechanism of heat-shock protection in ISKNV-infected tilapia brain cell line

Microbiology Spectrum
Infectious spleen and kidney necrosis virus (ISKNV) is the causative agent of a fatal disease in many fish species, resulting in mass mortalities and significant economic losses.

Phenotypic Florfenicol Resistance in floR‐Harbouring Flavobacterium psychrophilum Isolates (CC‐ST90): A Case Study From Danish Freshwater Rainbow Trout Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Monitoring antimicrobial resistance (AMR) in fish pathogens is essential for supporting sustainable aquaculture. In this study, susceptibility testing and genome sequencing were used to characterize the AMR profile of seven Flavobacterium psychrophilum originating from Danish rainbow trout farms (2019–2022).

The viral ankyrin repeat protein (ORF124L) from infectious spleen and kidney necrosis virus attenuates nuclear factor-κB activation and interacts with IκB kinase β

, 2011
The ankyrin (ANK) repeat is one of the most common protein–protein interaction motifs, found predominantly in eukaryotes and bacteria, but the functions of the ANK repeat are rarely researched in animal viruses, with the exception of poxviruses ...

Francisella orientalis in Aquacultured Tilapia (Oreochromis spp.): A Case Work‐Up of Diagnostics and Pathologic Findings in the North Central Region (USA)

Journal of Fish Diseases, EarlyView.
ABSTRACT Tilapia (Oreochromis spp.) is an increasingly popular aquacultured fish worldwide. While tilapia enjoy a ‘hardy‐fish’ reputation among fish farmers, they are susceptible to a variety of infectious diseases that can be difficult to recognize pondside and have similarities in their gross presentations. This report describes gross and microscopic

Trout oral VP2 DNA vaccination mimics transcriptional responses occurring after infection with infectious pancreatic necrosis virus (IPNV)

, 2012
Time-course and organ transcriptional response profiles in rainbow trout Oncorhynchus mykiss were studied after oral DNA-vaccination with the VP2 gene of the infectious pancreatic necrosis virus (IPNV) encapsulated in alginates.

Infectious Pancreatic Necrosis in Atlantic Cod (Gadus morhua): Complete Viral Genome Characterization From the First Norwegian Field Case Suggests Cross‐Species Transmission

Journal of Fish Diseases, EarlyView.
ABSTRACT We describe the first natural outbreak of infectious pancreatic necrosis (IPN) in farmed Atlantic cod (Gadus morhua) in Norway. IPN was originally described in young salmonids, but the greatest losses have historically occurred in Atlantic salmon (Salmo salar) following sea transfer despite high vaccination coverage.
