Summary: A rapid, simple, sensitive, and specific detection method based on loop-mediated isothermal amplification (LAMP) has been developed for the detection of Vibrio harveyi contamination. The addition of loop primers reduces the reaction time of LAMP by more than half, and with the use of SYBR Green, results can be obtained within 10 to 15 minutes without gel electrophoresis. LAMP has greater sensitivity compared to PCR.

Summary: Bacterial colonies composed of genetically identical individuals can diversify through T6SS-mediated cell death, resulting in variant cells with distinct genotypes. This variant outgrowth is regulated by quorum sensing and T6SS-driven killing, promoting genetic diversity in bacteria.

Summary: The potential application of N. oceanica, Isochrysis sp., and T. weissflogii as inhibitory bacteria and probiotics in controlling bacterial diseases in the aquaculture industry is investigated. Marine microalgae were found to produce antibacterial substances, with N. oceanica exhibiting the largest inhibitory zone against V. harveyi. These findings suggest that the hydrophilic chemicals in microalgae extracts have antibiotic activity against the highly virulent V. harveyi, providing potential solutions for preventing vibriosis in aquaculture.

Summary: Vibrio harveyi isolated from marine food fish cultured in Korea showed high virulence factors and antimicrobial resistance, with most classified as multidrug resistant, posing a threat to the effectiveness of antimicrobial treatments. Various virulence genes and antimicrobial resistance genes were detected in the isolates, indicating the potential development of more virulent strains with increased antimicrobial resistance.

Summary: Mussels were found to be the most sensitive to xenobiotic exposures, while gastropods were the least sensitive with particular substrate-specific preferences. Among all species, the plastic additive tetrabromobisphenol A displayed the highest CE-inhibitory capacity.

Summary: VhCBP is a protein responsible for the translocation of chitooligosaccharides in marine bacteria, displaying highest affinity towards (GlcNAc)(2). Mutation of specific residues can drastically reduce the binding affinity towards the preferred substrate. The structure of VhCBP in complex with (GlcNAc)(2) reveals an intermediary step in the translocation process.

Summary: This study identified specific miRNAs in the epidermal mucus of fish infected with Vibrio harveyi, which can serve as disease-related biomarkers. These miRNAs can be used to differentiate diseased and healthy fish and provide new insights into the mechanism of bacterial infections in fish.

Summary: Biofilms can cause serious issues in medical and marine environments, and current anti-biofilm solutions that use biocides come with the risk of antibiotic resistance and pollution. Therefore, there is a need for ecofriendly solutions that rely on the anti-adhesive properties of materials. This study focuses on the effect of a specific exopolysaccharide on the growth and dispersion of pathogenic model strains, and the results show that it can limit biofilm formation without any biocidal activity.

Summary: This study analyzed 25 non-cholera Vibrio spp. isolated from marine sponges and sea urchins collected at the coastlines of Brazil and France, finding that 64% were non-susceptible to antibiotics and 8% were multidrug-resistant. Several genes related to resistance, virulence, and plasmids were detected. These findings contribute to a better understanding of antibiotic resistance in aquatic environments, suggesting that Vibrio associated with marine animals may pose a potential risk to public health.

Summary: This literature review identifies major environmental indicators and their optimum variation ranges for the prevalence of Vibrio parahaemolyticus in the marine environment. The study shows that the prevalence of Vibrio parahaemolyticus is primarily influenced by Sea Surface Temperature (SST), salinity, pH, chlorophyll a, and turbidity, in descending order of importance. Each environmental indicator has an optimum range that favors the presence of Vibrio parahaemolyticus.

Summary: Four biofilm-inhibiting endophytic fungi from two species of mangrove trees were tested and found to protect shrimp against Vibrio pathogens. These inhibitors have the potential to be used as feed supplements to prevent or reduce bacterial disease infections in shrimp, serving as prophylactic alternatives to antibiotics.

Summary: In this study, the immune responses of blood clam hemocytes to Vibrio infection were investigated. It was found that after 24 hours of infection, the expression of immune-related genes and the production of antimicrobial substances in the serum and hemocytes significantly increased. However, the number of hemocytes and the percentage of red granulocytes decreased significantly. These findings provide new insights into the hemocyte immune mechanism against Vibrio infection in T. granosa.
