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: This study analyzed the genetic diversity, virulence gene prevalence, antibiotic resistance phenotype, and antimicrobial resistance gene risk diversity of Vibrio alginolyticus isolated from different geographical locations in China. It found complex correlations among antibiotic phenotypes, resistance, and virulence genes under different genotypes of V. alginolyticus. The results provide a theoretical foundation for understanding the genetic and metabolic diversity of V. alginolyticus in China, and for assessing transmission risk and regional diagnosis of Vibrio in aquatic animals.

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: 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 found that vanillic acid exhibited good antibacterial activity against the fish pathogen Vibrio alginolyticus, causing cell membrane damage and increasing membrane permeability in a dose-/time-dependent manner. Additionally, vanillic acid significantly reduced biofilm formation, mobility, exotoxin production, and downregulated virulence-associated genes in V. alginolyticus. These findings suggest that vanillic acid may be a promising agent for treating infections associated with V. alginolyticus in aquaculture.

Summary: The study showed that using a consortium of microalgae and bacteria in algaebacterial systems significantly improved the removal of different bacteria. Addition of CO2 or O2 enhanced the removal of certain bacteria but could decrease the removal of others. Different light cycles also had an impact on the removal of different bacteria.

Summary: This study aimed to investigate the potential of Ulva papenfussi and Ulva nematoidea macroalgae as alternatives for preventing vibriosis in Litopenaeus vannamei caused by Vibrio parahaemolyticus. Phytochemical screening revealed the presence of phenols, polyphenols, flavonoids, and carbohydrates in both macroalgae. In vitro tests showed that crude extracts of these macroalgae exhibited antibacterial activity against V. parahaemolyticus. The results suggest that these macroalgae could be considered as potential feed additives for L. vannamei. This study provides the first report on the phytochemical screening and antibacterial activity of these macroalgae against V. parahaemolyticus. Rating: 7 out of 10.

Summary: Cystic fibrosis (CF) is a disease associated with repeated lung bacterial infection, often leading to therapeutic failure and death. In this study, methacrylate-based copolymers were evaluated for their antibacterial activity against CF-associated bacterial strains. The results showed that certain copolymers possessed strong antibacterial activity, rapid membranolytic effect, and prevention of biofilm formation, making them potential alternatives to conventional antibiotics in the treatment of CF-associated bacterial infection.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.
