Summary: The heavy metal bismuth (III) chelated with deferiprone showed effective antibacterial properties in aquaculture systems, reducing antibiotic use and mortality rates. Most aquaculture bacterial pathogens exhibited decreased growth ability in the presence of bismuth concentrations, with high variability between species and strains. Bismuth therapy, potentially in combination with other antimicrobials, could help reduce antibiotic use in aquaculture.

Summary: This study presents the development and evaluation of a method for the early quantification of Vibrio alginolyticus, Listonella anguillara, and Vibrio harveyi using real-time polymerase chain reaction (qPCR), with a new primer pair targeting the groEL gene. The most efficient DNA extraction method was the DNeasy Blood and Tissue kit. Adjustment of the DNA control's standard curve to the relevant extraction matrices is important for accurate quantification using qPCR.

Summary: This study investigates the genetic differences and evolution of the most common fish pathogen Vibrio anguillarum serotype O1. The O1 strain has two chromosomes and two typical plasmids. Furthermore, the O1 strain displays resistance to colistin sulphate, which differs from the O2 serotype and may be attributed to the ugd gene. The study also reveals that the genetic heterogeneity in the O-antigen biosynthesis gene cluster is characterized by the absence or presence of unique genes, which could result in differences in immune evasion mechanisms among serotypes.

Summary: This study investigated natural bacterial infection in fish farms and characterized the health status parameters of rainbow trout. Three subpopulations of infected trout with varying severity of damage, from severe lesions to asymptomatic fish, were identified. Unexpectedly, there was minimal metabolic difference between fish with moderate symptoms and fish with weak signs of pathology. The study also examined the pathogenesis of Vibrio anguillarum infection in rainbow trout and identified molecular markers for diagnosing health and immune status in trout.

Summary: The study investigated how Vibrio anguillarum adapts to stress conditions related to vibriosis through proteomic analysis, revealing specific protein adaptations under different stresses. Iron deprivation and exposure to Atlantic salmon serum led to upregulation of iron acquisition mechanisms in VA. The findings provide insights into potential virulence determinants and can improve intervention strategies for controlling vibriosis in aquaculture.

Summary: Vibrio europaeus, an emerging pathogen affecting bivalve species in Spanish and French hatcheries, has been identified for the first time outside Europe in Chile and the US West Coast. The worldwide spreading and potential impact of V. europaeus for aquaculture is significant, as these four countries are among the top 10 mollusk producers. Pathogenicity of V. europaeus towards scallop, an important species for Chilean mariculture, has been demonstrated for the first time.

Summary: The presence of virulence determinants in Vibrio species isolated from water resources in South Africa poses a potential public health risk. The study highlights the relevance of environmental Vibrio species to the epidemiology of vibriosis and cholera-like infections. A monitoring program for pathogenic Vibrio species, especially in surface water, is recommended.

Summary: Two Vibrio strains (VPAP36 and VPAP40) isolated from moribund-settled larvae of the Chilean scallop Argopecten purpuratus were identified as Vibrio chagasii and exhibited virulence properties. Whole genome analysis revealed the presence of virulence factors and Quorum Sensing genes in both strains, while metalloproteinase and capsular polysaccharide genes were only detected in VPAP40. In challenge bioassays, VPAP36 and VPAP40 showed significant differences in their larval lethal activity, with VPAP36 causing higher mortality. This study is the first to report the isolation of V. chagasii from larval mortalities of farmed Chilean scallops, highlighting its pathogenicity.

Summary: Vibrio-associated ailments, which are common among both marine aquaculture systems and wild fish populations, can have significant economic impacts on fish farms. The disease, known as vibriosis, is characterized by skin lesions, haemorrhages, and septicaemia. Although fish of any age group can be infected, young animals are more susceptible. The infection occurs when the bacterium attaches to the host tissue, followed by invasion into internal organ systems. Understanding the pathology, pathogenesis, and virulence factors of Vibrio bacterium is crucial for controlling the emergence of vibriosis.

Summary: The study revealed that gills are the most common parasitic site for L. anguillarum and V. alginolyticus in cultured European sea bass. Intraperitoneal injection of V. alginolyticus FKC bacterin is the most effective administration route, providing protection against V. alginolyticus and cross-protection effects.

Summary: In this study, exosomes were isolated from Vibrio harveyi and Vibrio anguillarum using a supercentrifugation method, and their protein compositions were analyzed. The exosomes of these two vibrios contained virulence factors and also played roles in important bacterial activities. Further experiments confirmed the involvement of exosomes in vibrio toxicity. This study provides a valuable proteome database for understanding the pathogenic mechanisms of vibrios from the exosome perspective.

Summary: This study systematically reviewed the feasibility of using Vibrio spp. and their vibriocins as a control measure for vibriosis in aquaculture. The results showed that Vibrio spp. can be used as a probiotic for vibriosis control, while vibriocins exhibited narrow-spectrum activity against Vibrio spp., making them a targeted control measure.

Summary: This paper reviews the inhibition of Vibrio spp. by essential oils (EOs) and the potential toxicity of EOs towards crustaceans, with a focus on Artemia spp. The study reports 27 EOs from terrestrial plants that show anti-Vibrio activity, with Salvia officinalis and Thymus vulgaris being the most commonly studied. Among Vibrio spp., V. parahaemolyticus (non-AHPND strain) is the most researched. The toxicity of EOs in Artemia spp. is discussed, with 37 EOs showing strong toxicity, 15 EOs showing moderate toxicity, 3 EO plants showing weak activity, and 13 extracts being non-toxic. Some EOs were found to be strongly toxic to Artemia, indicating the need for careful and ecologically safe use in shrimp aquaculture.
