Summary: The study identified a teleost SNX8 cDNA from grass carp, which was significantly up-regulated after infection and mainly distributed in the endoplasmic reticulum. CiSNX8 may negatively regulate the RLR signaling pathway and interact with multiple proteins, suggesting its involvement in innate immune response through different molecular mechanisms.

Summary: This study investigated the immune protective effects of an inactivated F. columnare vaccine. The results showed that when white oil adjuvant was used as a booster, the relative percent survival (RPS) after 8 weeks of vaccination was 34% and 61%, respectively. Furthermore, the inactivated vaccine comprising an appropriate antigen isolate with white oil adjuvant as a booster can provide effective protection in grass carp.

Summary: The study illustrates that excessive lipid accumulation in farmed fish liver may be a protective response to exogenous fatty acids. Inhibition of DGAT1 and DGAT2 in grass carp hepatocytes shows that DGAT1 is responsible for lipid droplet formation while DGAT2 promotes lipid droplet fusion. This indicates a differential role of DGAT1 and DGAT2 in lipid metabolism and liver health in farmed fish.

Summary: The study found that oregano essential oil and nisin have significant effects on the shelf life and microbial community of fish fillets, with the combination of oregano essential oil and nisin showing the best results. The addition of these two substances can effectively extend the shelf life of fish fillets and inhibit microbial growth, especially lactic acid bacteria.

Summary: Cadmium is a dominant metal pollutant in aquatic environments that affects ion balance, oxidative stress, and immune responses in aquatic organisms. The addition of calcium can mitigate the toxicity of cadmium by reducing its accumulation in tissues, maintaining ion balance, alleviating oxidative stress, and regulating ATPase activity and gene expression.

Summary: This study isolated 45 bacterial strains of F. columnare from grass carp in various provinces of China, identifying three genotypes with genomovar I being the dominant type. Analysis revealed genetic differences among the three genomovars, with a closer relationship between genomovar I and II. The study provides insight into the genetic diversity of F. columnare in Chinese grass carp.
