cds46, a highly variable carp edema virus gene.

Carp edema virus disease (CEVD) is a severe viral illness that causes substantial economic losses in wild and farmed common carp and koi. It is caused by carp edema virus (CEV), a member of the family whose genetic diversity and genome evolution are poorly understood. Based on a genomic fragment of the gene, two genogroups, genogroup I (gI) and genogroup II (gII), have been identified in samples of different origins.

A Kinetic Approach to Synergize Bactericidal Efficacy and Biocompatibility in Silver-Based Sol-Gel Coatings.

Silver ions are antimicrobial agents with powerful action against bacteria. Applications in surface treatments, as Ag-functionalized sol-gel coatings, are expected in the biomedical field to prevent contaminations and infections. The potential cytotoxicity of Ag cations toward human cells is well known though.

A plant-based diet differentially affects the global hepatic methylome in rainbow trout depending on genetic background.

Replacing fish meal and oil in trout diets with plant-derived ingredients is a contemporary challenge to move towards more sustainable aquaculture practices. However, such dietary replacement causes hepatic metabolic changes that have not yet been elucidated. Here, we aimed to decipher the effect of a 100% plant-based diet on the hepatic global DNA methylation landscape in trout and assess whether changes depend on fish genetic background.

Hepatic Global DNA Hypomethylation Phenotype in Rainbow Trout Fed Diets Varying in Carbohydrate to Protein Ratio.

Background: A high carbohydrate-low protein diet can induce hepatic global DNA hypomethylation in trout. The mechanisms remain unclear.

Objectives: We aimed to investigate whether an increase in dietary carbohydrates (dHCs) or a decrease in dietary proteins (dLPs) can cause hepatic global DNA hypomethylation, as well as explore the underlying mechanisms in trout.
