Summary: The study explored the effects of Greek juniper extract on immune responses of rainbow trout, showing that the extract had various impacts such as increasing lysozyme activity, decreasing myeloperoxidase activity, and up-regulating interleukins. Additionally, the juniper extract demonstrated a protective effect against Yersinia ruckeri, leading to a higher survival rate in rainbow trout treated with it.

Summary: The study revealed a co-infection of Yersinia ruckeri and Pseudomonas fluorescens in rainbow trout farms in Mugla, Turkey, causing significant mortalities and pathological signs. The pathogens were identified through biochemical and molecular tests, showing resistance to various antibiotics. Infection experiments indicated high mortality rates and pathogenicity of both Y. ruckeri and P. fluorescens.

Summary: This study utilized RNA-seq analysis to investigate the molecular mechanism of immune response in rainbow trout spleen during Flavobacterium psychrophilum infection. The results revealed key signaling pathways and provided valuable insights for future research on prevention and control of bacterial coldwater disease in salmon culture.

Summary: This study evaluated the short-term innate immune response of rainbow trout to infection with Y. ruckeri. The results showed significant decreases in hematological parameters and oxidative stress indicators in the infected group compared to the control group. There were also significant differences in gene expression between infected individuals and the control group.

Summary: The use of enrofloxacin in trout farms for the treatment of yersiniosis should be reevaluated, as a single intraperitoneal injection of ENR at 10 mg/kg appears to be more effective than repeated oral administrations. This study suggests the need for revising the oral doses used in trout farms.

Summary: This study investigated the latent infection of Yersinia ruckeri in rainbow trout, finding that qPCR detection of the bacteria in spleen DNA is a preferred standard for carrier detection. The research highlights the importance of effective monitoring for subclinical infections in aquaculture for proactive disease management.

Summary: PACAP has been found to have antimicrobial and immunomodulatory effects in fish, making it a potential alternative to antibiotics in the aquaculture industry. The study demonstrates that PACAP can directly inhibit bacterial growth and pre-treatment with low concentrations of the peptide significantly suppresses infection.

Summary: The aqueous methanolic extract of thin-skinned plum showed positive effects on the growth, immune response, and resistance to a pathogenic bacterium in rainbow trout. Specifically, it improved innate immunity, survival against Yersinia ruckeri, and decreased the feed conversion ratio level significantly.

Summary: This study investigated the effect of taxifolin on rainbow trout under heat stress and Gyrodactylus flatworm infection. The results showed that taxifolin can alleviate heat-induced responses in fish and regulate the expression of apoptosis regulators, but has no significant effect on antioxidant enzyme expression. Taxifolin treatment does not affect the parasite load of Gyrodactylus infection.

Summary: In this study, the researchers found that the T4SS of Yersinia ruckeri SC09 mediated bacterial virulence and immune evasion, possibly through the secretion of molecules such as STIR-1, STIR-2, and STIR-3. These findings contribute to a better understanding of the general rules of bacterial pathogenicity.

Summary: The study found that exposure to hypoxia led to a significant increase in erythroid progenitor proliferation in mice spleen, accompanied by a decrease in overall gene expression. Stress erythropoiesis was regulated by three transcription factors, and the expression of genes related to immune response was downregulated.

Summary: This study used RNA sequencing technology to analyze the transcriptome profiles in spleens of rainbow trout infected and uninfected with infectious hematopoietic necrosis virus (IHNV). A total of 9144 differentially expressed genes (DEGs) were identified, with most DEGs significantly enriched in major immune terms and signaling pathways. The expression levels of six key immune-related genes in four important immune signaling pathways were also detected. The results provide a better understanding of the dynamic immune response of rainbow trout infected with IHNV and lay a foundation for further study of molecular mechanisms of anti-IHNV innate immunity.
