Summary: Aquatic food is an important source of micronutrients for human beings, and aquaculture plays an increasingly important role in providing this food source. However, bacterial infection poses a severe threat to aquaculture and strategies for managing these infections without antibiotics are lacking. This study investigates the metabolic changes of crucian carp infected with Aeromonas hydrophila and identifies fructose as a crucial biomarker. Supplementation of fructose increases fish survival rate by enhancing the expression of lysozyme and complement 3, leading to reduced bacterial load. These findings demonstrate a metabolism-based approach to manage bacterial infection by modulating the immune response.

Summary: The application of nanotechnology in aquaculture for developing efficient vaccines has shown great potential. Nanovaccination, through encapsulating fish pathogen antigens and achieving sustained release, enhances immune responses and protective efficacy of vaccines. However, thorough evaluation of the potential toxicity of nanoparticles is necessary before widespread application.

Summary: Pharmaceuticals and nutrients need to cross various barriers to enter and be eliminated from the body. The gastrointestinal mucosa acts as a critical barrier, facilitating nutrient transport and impeding the transit of toxins and bacteria. This study investigates the penetration of particles and drugs through the mucus layer, finding that internal fluid flow has a significant impact on particle transport, necessitating the consideration of convection mechanism for mass transfer.

Summary: A high-density PEGylation-based glycocholic acid-decorated micelle (PTX@GNPs) was constructed to overcome the obstacles in the gastrointestinal environment. This micelle possesses mucus trapping escape ability and excellent intestine epithelium targeting, enhancing the oral bioavailability of paclitaxel (PTX) and exhibiting similar antitumor efficacy compared to intravenous injection. Furthermore, it can increase in vivo retention time of PTX and remodel the immune microenvironment, enhancing oral chemotherapy efficacy.

Summary: IL-21 is induced in grass carp leukocytes and tissues in response to bacterial infection. It promotes the expression of antibacterial genes and inhibits the NF-kappa B signaling pathway. IL-21 is expressed in CD3γ/δT cells and accumulates in the intestine, indicating its important role in regulating intestinal inflammation induced by bacterial infection in grass carp.

Summary: Mucus is a viscoelastic gel that traps pathogens and foreign particles, while also being essential for drug carriers to access underlying epithelial tissues. Various strategies have been developed to achieve mucoadhesion and mucus penetration in drug delivery systems. Advances in materials chemistry have led to the expansion of materials available for mucosal drug delivery applications.

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: The study revealed that challenge with Aeromonas hydrophila could lead to erythrocyte hemolysis, increased free hemoglobin levels, and decreased antioxidant capacity and enzyme levels in red crucian carp and triploid hybrid fish. Elevated expression of various proteins and metabolic products were observed in infected fish, highlighting the differential metabolic responses to bacterial infection.

Summary: This study reported an outbreak of disease in pirarucu caused by Aeromonas, conducted experimental co-infection research, and characterized resistance profile, virulence factors, and phenotypic and molecular differentiation. The findings support the existence of synergism between A. hydrophila and A. jandaei in pirarucu, with implications for occurrences of this co-infection and determinants of virulence.

Summary: In land-based recirculating aquaculture systems, low water salinities can impact the disease resistance of shrimp and alter the microbial composition, posing a higher risk of disease outbreaks and potentially affecting food safety. Maintaining high water salinities is recommended for producing healthy shrimp as safe food for human consumption.

Summary: This study investigates the occurrence of antimicrobial-resistant Escherichia coli in free-living great cormorants in Germany. The results show that resistant E. coli were isolated from a significant proportion of the samples, and a substantial number of the resistant isolates exhibited multidrug resistance. Most of the isolates belonged to the phylogenetic group B1, and a portion of them were identified as avian pathogenic E. coli with multidrug resistance. These findings provide valuable information on the dissemination of antimicrobial-resistant bacteria in wild birds and potential public health concerns.

Summary: Tilapia tilapinevirus (TiLV) is a newly emerged virus that causes a novel disease and reduces tilapia populations worldwide. It has been reported in 17 countries, causing high mortalities. Currently, there are no therapeutics or vaccines specifically designed for TiLV control. Vaccination has shown potential in inducing protective immunity in tilapia. Various vaccine strategies are being explored, but a comprehensive overview of their efficacy is lacking. This review discusses recent advances in TiLV vaccine development, highlighting the need for further research and the incorporation of different approaches to enhance vaccine effectiveness.
