Summary: By tagging pathogenic Vibrio strains with green fluorescence protein, a new pathogenesis of vibriosis in bivalve larvae was identified. The pathogens entered the larval digestive organs rapidly, inducing necrosis and eventually leading to larval death. This study lays a foundation for further research on gastrointestinal morphology after anti-Vibrio therapy introduction in aquaculture.

Summary: This study isolated V. gigantis strain C24 from hatchery-reared European seabass broodstock in T & uuml;rkiye and characterized its properties. The strain showed pathogenicity and resistance to certain antibiotics, indicating its potential threat to the European seabass production industry. This is the first report of V. gigantis as an emerging bacterial pathogen in T & uuml;rkiye.

Summary: The study found that the immunity in the early stages of Pacific oyster larvae is not strong enough to prevent vibriosis, with Vibrio strains first colonizing the digestive system and rapidly proliferating, leading to necrosis in the larval digestive system.

Summary: This study investigated the early stages of Johne's disease caused by MAP in a calf model infected with Argentinean isolates of the pathogen. The study found that specific IFN-gamma was not a reliable indicator for early detection of MAP infection in calves. TNF-alpha expression was higher than IL-10 in infected animals at 110 days post-infection, but decreased significantly compared to uninfected calves. Further studies are needed to understand the influence of MAP strains on host-pathogen interactions and disease outcomes.

Summary: Viral nervous necrosis (VNN) is an acute viral disease affecting cultured marine fish, but cichlid fish, particularly Etroplus species, show a low susceptibility or resistance to this disease. Experimental results with orange chromide(Etroplus maculatus) showed moderate resistance to nervous necrosis virus (RGNNV genotype) with a survival rate of 50-75%.

Summary: The market for Pacific bluefin tuna is expanding due to global consumption increases, leading to overfishing and depletion. Aquaculture is being promoted as an alternative, but infectious diseases are a common problem. Research shows that oral infection is effective for reproducing red seabream iridoviral disease in Pacific bluefin tuna.

Summary: This study investigated the prevalence of Vibriosis outbreaks in marine finfish farms in India, revealing Vibrio species accounted for 83.2% of bacterial isolates, with V. harveyi being the predominant pathogen. Photobacterium damselae was found to be the least common. In a pathogenicity study, high mortality rates were observed in seabass fingerlings exposed to V. harveyi. The efficacy of probiotics in controlling V. harveyi warrant further research.

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: COVID-19 infection caused by SARS-CoV-2 poses a diverse range of liver damage, from asymptomatic abnormalities to hepatic decompensation, which are correlated with disease severity and mortality rates. Although SARS-CoV-2 RNA has been detected in the liver of patients, the specific mechanism of infection and replication in liver cells remains unclear.

Summary: The study utilized the greater wax moth Galleria mellonella as an in vivo model of gonococcal infection, demonstrating that a relatively small number of bacteria could cause larval death and significant histopathological changes. The model was used to test the anti-gonococcal properties of antibiotics and novel antimicrobials, with ceftriaxone showing protective effects against infection.

Summary: This review is based on the studies on vibriosis, specifically on the various treatments and their limitations, as well as the potential application of graphene oxide (GO) nanoparticles in aquaculture. GO has shown anti-bacterial properties against both Gram-positive and Gram-negative bacteria, but no research has been published regarding its impact on Vibrio spp. This review aims to explore the potential use of GO for the treatment of vibriosis.

Summary: This study evaluated three different routes of Streptococcus agalactiae infection in Nile tilapia and found that intraperitoneal and intragastric routes were more aggressive, causing greater brain damage and early mortality, while oral inoculum presented less intensity in brain lesions and a chronic immune response, with longer mortality time. Oral infected-feed administration may be an innovative method for future aquaculture research experiments.

Summary: This study evaluated the use of two microencapsulated probiotic additives in extruded diets for juvenile Nile tilapia, and found that the addition of probiotics improved the zootechnical and health aspects of the fish. The fish fed with probiotic diets showed greater survival, improvements in feed conversion, as well as in the specific growth rate. Histological and histomorphometric analysis revealed that the probiotic treatments had a positive effect on the intestinal health of the fish. Metagenomic evaluation also showed significant differences in the intestinal microbiomes between the treatments. In the challenge against the pathogen A. hydrophila, the probiotic treatments exhibited lower cumulative mortality compared to the control group.

Summary: Fish parasites, such as Neoechinorhynchus buttnerae, can accumulate high concentrations of trace metals and serve as bioindicators of environmental contamination. The presence of metals in the parasite was significantly higher than in the host fish Colossoma macropomum, indicating their ability to accumulate metals. The results suggest that the parasite directly influences the concentrations of trace metals in the fish tissues.

Summary: This study evaluated the pharmacokinetic profile of basil essential oil in juvenile tambaqui. The results showed that the oil was rapidly absorbed and distributed to different tissues in the fish, with varying half-lives in plasma and various tissues. Histological evaluation of the fish gills showed reversible lesions, while no changes were observed in the liver and spleen. The biochemical and pharmacokinetic results confirmed the safety and rapid elimination of basil essential oil in tambaqui.

Summary: This study aimed to evaluate the effectiveness of a mint hydrolate bath in controlling monogeneans in four species of tilapia reared in the same environment. The results showed that the mint hydrolate bath had an efficacy ranging from 73.5% to 84.5% against monogeneans in the mucus of the fish. All species demonstrated similar susceptibility to parasites and the mint hydrolate bath was effective in controlling monogeneans in the mucus for all evaluated species.
