Summary: Photobacteriosis is a bacterial disease that affects various marine species globally, leading to significant economic losses. Despite studies on pathogen virulence and resistance, information on host defense mechanisms post-infection remains limited. This study focused on innate immune responses of farmed juvenile gilthead seabream after infection with Photobacterium damselae subsp. piscicida, revealing marked changes in blood parameters and gene expression related to inflammation and phagocytic activity. Further research on different fish species and pathogens could help identify health biomarkers for disease prevention in aquaculture.

Summary: It is known that intensive farming exposes fish to multiple sources of stress, increasing their susceptibility to pathogens and disease outbreaks, which can lead to economic losses. In recent years, research has focused on using bioactive compounds from microalgae, plants, and microorganisms as dietary supplements to improve fish growth performance, health, and immune system. The use of natural immunostimulants is considered a promising alternative to promote fish health, productivity, and sustainability. This study evaluated the effects of adding Halobacterium salinarum, a potential probiotic strain, in the diet of farmed gilthead seabream on growth and immune responses.

Summary: In this study, Schiff base derived organosilatranes with pyridine moiety were successfully synthesized using a simple method. The structure of the compounds was determined through various spectroscopic studies. The chemosensor exhibited high selectivity and sensitivity towards Zn2+ ions, as evidenced by significant changes in UV-vis and fluorometric spectra. Immobilizing the organosilatrane on silica nanoparticles surface enhanced its binding capacity for Zn2+ ions and showed potential for water treatment applications. Additionally, the synthesized organosilatranes showed promising pharmacokinetic profiles and cytotoxicity in biological field applications.

Summary: The role of adipocytes and fatty acids in carrageenan-induced skin inflammation was studied in gilthead seabream. Results showed that injection of lambda-carrageenin led to an increase in adipocyte area at 3 hours post-injection and an increase in adipocyte frequency at 6 hours post-injection. Analysis of lipid classes revealed increased levels of free fatty acids and sphingomyelin in the injected fish compared to the control group. The fatty acid profile of the fish skin also showed changes, with an increase in saturated fatty acids and n-6 polyunsaturated fatty acids, and a decrease in monounsaturated fatty acids, n-3 polyunsaturated fatty acids, and minor fatty acids at 6 hours after injection. Evaluation of eicosanoids indicated an increase in hydroxyeicosatetraenoic acid in the injected fish compared to the control group. These findings demonstrate the contribution of adipocytes and fatty acids to the inflammatory response in gilthead seabream skin.
