Summary: Transmission of infectious salmon anemia virus (ISAV) in seawater can be detected through analysis of ISAV RNA, with viral shedding peaking before fish mortality. The combination of an electronegatively charged filter with lysis buffer shows significantly higher detection of ISAV RNA in seawater samples.

Summary: This study investigated the impact of four experimental functional feeds on Atlantic salmon during a single infection with sea lice and a co-infection with sea lice and infectious salmon anemia virus (ISAv). Transcriptomic analysis revealed different gene expression responses in the skin tissues of fish with different experimental diets. The co-infection group showed lower survival rates and up-regulated genes associated with glycolysis and immune response pathways. Understanding the effects of experimental functional feeds on the host response and co-infection trajectory is crucial for developing effective intervention strategies in open cage culture.

Summary: The nonvirulent infectious salmon anaemia virus (ISAV-HPR0) causes prevalent and transient infections in all three production stages of Atlantic salmon in the Faroe Islands. Different HPR0 subgroups dominate in different stages of production, and vertical transmission of HPR0 from broodfish to progeny is uncommon.

Summary: The present study found that triploid Atlantic salmon are more susceptible to infectious salmon anaemia (ISA), which increases the risk of ISA outbreaks. It is recommended to separate triploid and diploid fish in farming or not farm triploid fish at all.

Summary: Bacterial cell envelopes play a critical role in host-pathogen interactions and are closely linked to the virulence of pathogens. This study focuses on the genetic approach of knocking out genes related to membrane-associated polysaccharide biosynthesis in Piscirickettsia salmonis. The knock-out mutants were found to affect the virulence and pathogenicity of P. salmonis.

Summary: The research team developed a mathematical model based on the advection-diffusion equation to predict dissolved oxygen levels in fish sea cages. The model was tested in a large production unit and performed well, but may require more detailed information on fish behavior and current conditions within the cages to improve accuracy.

Summary: The gut microbiota of wild Baltic salmon parr was found to differ from those of wild North- and East-Atlantic salmon parr, possibly due to biogeographical differences or host-selective pressures as a result of the Baltic salmon population splitting from the Atlantic salmon population in the Ancylian period.

Summary: This study examined the immunogenicity and protective effect of a vaccine against Lepeophtheirus salmonis infestation in Atlantic salmon. The results showed that the vaccine can provide protection against salmon lice infestation, and the level of protection is dose-dependent. The study also found that the vaccine can trigger a specific immune response in vaccinated fish and result in the production of specific antibodies. These findings suggest the potential of using the parasite's feeding behavior to deliver salmon-specific antibodies against lice-gut proteins.

Summary: The Norwegian government has introduced a new type of aquaculture license to address environmental issues in salmon farming. New technological solutions have been proposed, including expansion to open ocean areas and reduced emissions. The analysis of license applications reveals that future marine aquaculture will involve larger and stronger units, with a focus on design diversity.

Summary: Tasmanian salmon industry was relatively free of major viral diseases until pilchard orthomyxovirus (POMV) emerged, which poses a significant threat to farmed Atlantic salmon. The virus was found to be transmissible in sea water without the need for direct contact between fish, with high viral loads in head kidney and heart during early infection stages. Understanding POMV transmission and host-pathogen interactions is crucial for developing improved surveillance tools, transmission models, and disease prevention strategies.

Summary: Developing an effective and economical vaccine against Piscirickettsia salmonis is crucial for sustainable salmon farming. One vaccine prototype effectively protected Atlantic salmon by inducing specific antibodies and pro-inflammatory cytokines, while the other two activated innate immune responses but did not provide protection. Understanding the protein formulation of vaccines based on P. salmonis is essential for improving immune responses and disease resistance in Atlantic salmon.

Summary: Two slc15a2-type genes were identified in the Atlantic salmon genome, encoding PepT2-type peptide transporters. While slc15a2a transcripts are widely distributed in fish tissues, abundant in the brain and gills, slc15a2b transcripts are mainly expressed in the kidney and distal gastrointestinal tract. Both PepT2a and PepT2b function as high-affinity transporters.

Carotid and femoral Doppler ultrasound (DUS) were used to stratify the patients and optimize the assessment of asymptomatic cardiovascular disease. The results showed that DUS was effective in detecting cardiovascular abnormalities in RA patients, and the EULAR criteria was successful in identifying high cardiovascular risk patients.

Summary: Patagonian fjords have been experiencing severe harmful algal blooms (HABs) in recent years, particularly due to climatic anomalies and persistent thermal stratification. The bloom of Heterosigma akashiwo in Comau fjord in March-April 2021 resulted in high salmon mortalities. The outbreak was influenced by the positive phase of the Southern Annular Mode and the drought caused by low rainfall and increased water temperature.

Summary: This study evaluated the activation of nutritional immunity in Atlantic salmon stimulated with live and inactivated Piscirickettsia salmonis. The results showed that both live and inactivated P. salmonis could activate nutritional immunity, and there was no distinction between the two. Genetic material of P. salmonis was detected in the liver tissue of the fish. The hematocrit percentage decreased in fish stimulated with live P. salmonis, while it remained unchanged in fish stimulated with inactivated P. salmonis. Plasma iron content decreased in both experimental groups, but the decrease was statistically significant only at 3 dpi. Immune-nutritional markers were modulated in both experimental conditions, while other markers were down-regulated. Intracellular iron content increased in the liver at 7 and 14 dpi, while zinc content decreased at 14 dpi in both experimental groups. However, manganese content was not altered by the stimulation. These findings suggest that nutritional immunity responds similarly to live and inactivated P. salmonis, and may be self-activated by the detection of PAMPs rather than a sequestration and/or competition of micronutrients by the living microorganism.

Summary: This study reveals the association of Piscine orthoreovirus (PRV) with HSMI and jaundice syndrome in coho salmon in Chile. Two variants of PRV-3 were identified, with PRV-3a being the predominant variant in recent years. Unique genetic characteristics were also found in the PRV-3 sequences from Chile. These findings emphasize the need for further research on the link between PRV and jaundice syndrome in coho salmon.

Summary: This review presents recent developments in the evolution of IAV in birds, mammals, and humans in Chile. It discusses the emergence of different IAV subtypes in poultry and pigs, the presence of reassortant AIVs incorporating genes from North and South American isolates in wild birds, and the detection of HPAI H5N1 in wild birds, sea lions, and a human along Chile's north coast. These findings highlight the need for enhanced biosecurity on poultry farms and ongoing genomic surveillance to understand and manage AIVs in both wild and domestic bird populations in Chile.

Summary: An unbalanced gut microbiota in fish may promote bacterial infections. However, the interactions between different bacterial groups and their effects on fish health are not well understood. This study found that pathogenic species were present in the digestive tract and gut mucosa of healthy salmon, and the dysbiosis in sick salmon may be associated with cooperative interactions between different taxonomic families of bacteria, leading to clinical symptoms.
