Summary: This study aimed to develop a method of infectious challenge in large Rainbow trout by immersion, simulating natural infection conditions. The results showed that a 24-hour contact period led to infection in all fish with a mortality rate of 53.25%. The infected fish developed acute infection symptoms and lesions similar to furunculosis, and antibodies against the bacterium were produced 4 weeks after challenging compared to the non-challenged group.

Summary: This study investigated the effect of a starch hydrogel-based oral vaccine on rainbow trout's antibody reactivity, immune-related genes expression, and protection against furunculosis infection. The results showed that the vaccine increased the agglutination titers and improved the survival rate of fish. Furthermore, the expression of immune-related genes was altered after vaccination.

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 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: 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 aimed to identify molecular mechanisms affected by a combined vaccine against Aeromonas salmonicida and Vibrio anguillarum. The vaccine upregulated gene expression associated with adaptive immune response markers and triggered differential expression of hundreds of genes on different days. Gene ontology and Kyoto Encyclopedia of Genetic and Genomic analyses identified immune system-related pathways and processes affected by the vaccine. Protein-protein interaction analysis revealed TNF as the central player in immune-related responses at different time points.

Summary: Rainbow trout is an important commercial fish, but infectious diseases can cause significant economic losses. Our study reveals the pathophysiological responses of the brain and kidney in rainbow trout infected with furunculosis, including neuroinflammation, neural dysfunction, and immunomodulation.

Summary: This study conducted transcriptomic profiling of spleen samples from rainbow trout at 24 h post-Y. ruckeri infection and identified 2498 differentially expressed genes related to immune response pathways. The findings provide insight into the molecular mechanisms of rainbow trout immune responses to Y. ruckeri infection.

Summary: This study examined the impact of probiotic bacteria on the immune response of trout intestinal cells infected with pathogenic bacteria. The results showed that the probiotic strain could reduce inflammation and modulate the immune response. Further in vivo experiments are needed to confirm its immunomodulatory potential.

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: The study used a PKPD approach combined with epidemiological data to determine optimal enrofloxacin doses in rainbow trout; results showed enrofloxacin should be considered as a long-acting drug in trout, raising concerns about the standard dosage; fish ploidy had an impact on the PK of enrofloxacin.

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: 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: This study investigated the effects of Dracocephalum kotschyi essential oil (DKE) on the growth, immune and antioxidant defense system, and resistance to bacterial infection in rainbow trout juveniles. The results showed that the DKE supplementation improved the immune response, antioxidant enzyme activity, and survival rate of the fish.
