Fish disease outbreaks caused by bacterial burdens are responsible for decreasing productivity in aquaculture. Unraveling the molecular mechanisms activated in the gonads after infections is pivotal for enhancing husbandry techniques in fish farms, ensuring disease management, and selecting the most resilience phenotype. The present study, with an important commercial species the European sea bass (Dicentrarchus labrax), an important commercial species in Europe, examined changes in the miRNome and transcriptome 48 h after an intraperitoneal infection with Vibrio anguillarum.

Introduction: People migrating to the Canary Islands by sea frequently suffer from potentially severe skin and soft tissue infections (SSTIs) for which optimal empirical antibiotic therapy is not well defined.
Methods: This descriptive retrospective observational study assess a case series of newly arrived maritime migrants to the Canary Islands who were diagnosed with clinical and microbiological SSTIs and admitted to the Nuestra Señora de La Candelaria Hospital in Tenerife between January 2020 and December 2023. Clinical data, bacterial species, resistance profiles, and choice of empirical treatments were analysed.
AIP56, an AB toxin secreted by subsp. , has tropism for myeloid cells.

Introduction: The AB-type toxin AIP56 is a key virulence factor of Photobacterium damselae subsp. piscicida (Phdp), inducing apoptosis in fish immune cells. The discovery of AIP56-like and AIP56-related toxins in diverse organisms, including human-associated Vibrio strains, highlights the evolutionary conservation of this toxin family, suggesting that AIP56 and its homologs may share conserved receptors across species.

, known as a global red tide species, is a common red tide species found in Pingtan Island. To examine the bacterial community structure in different environments during the red tide period of on Pingtan Island, samples were collected from the Algal Bloom Area (ABA), Transition Area (TA), and Non-Algal Bloom Area (NBA) on 6 April 2022, and the environmental physicochemical factors and bacterial community were determined. The outbreak of red tide significantly impacted the water quality and bacterial community structure in the affected sea area.
