This study investigates the immune responses of largemouth bass (Micropterus salmoides) to infection by Aeromonas hydrophila, a pathogen responsible for significant economic losses in freshwater aquaculture due to bacterial enteritis. We employed transcriptomic sequencing, label-free LC-MS/MS quantitative proteomics, and 16S RNA sequencing to evaluate the transcriptomic, proteomic, and intestinal microbiota changes in infected fish compared to healthycontrols. Each fish (approximately 60 g) in the infection group was injected with 0.

In this study, a virulent phage highly homologous to prophage in the genomes of was collected and preliminary biological characterization was carried out to understand its nature.
Materials And Methods: Water samples taken from eel ponds in Fujian, China were combined with the strain.
Epidemiological investigation on diseases of in Ningbo culture area.
Front Cell Infect Microbiol
July 2024
Article Synopsis
- High-density farming in Ningbo is leading to a significant increase in diseases caused by pathogens, which poses a major risk to sustainable bay farming in the area.
- An epidemiological investigation in 2023 involved regular monthly sampling of fish, revealing that a significant portion exhibited symptoms of pathogenic infections, with 55 fish sampled throughout the study.
- Results indicated that 78.18% of the sampled fish showed signs of pathogenic infections, predominantly from specific bacteria and parasites, while some fish had undetermined issues, underscoring the complexity of disease in aquaculture.
Hexavalent chromium (Cr(VI)) is known as the most hazardous species of chromium. Speciation analysis of Cr in foods is of a great significance for assessing its influences on human health. In this study, a fast HPLC-ICP-MS method for the determination of Cr(VI) was developed for determining the content of Cr(VI) and also investigating its transformation in foods.

However, the combined effects of Cu and Cd on the ovarian development of fish and other aquatic species remain unclear. In this study, female Nile tilapia (Oreochromis niloticus) were individually or co-exposed to Cu and/or Cd in water.

- * PCV2 infection significantly increases inflammatory cytokines and decreases HDAC (histone deacetylase) levels, which are involved in regulating gene expression for inflammation.
- * PSW treatment reduces the levels of pro-inflammatory cytokines and promotes HDAC expression, indicating its potential to modulate the inflammatory response and improve resistance to PCV2 infection.
Toxic inflammatory response is frequently introduced upon virus infection. In this study, RAW264.7 cells were infected with porcine circovirus type 2 (PCV2) and treated with Sargassum polysaccharide SP.

- The study looked at how Sophora subprosrate polysaccharide can help reduce inflammation caused by a virus called PCV2 in pig cells.
- It found that when the pig cells were treated with this polysaccharide, the levels of certain inflammation-causing substances went down while one helpful substance increased.
- The study suggests that this polysaccharide works by changing how certain proteins (histones) are modified, which helps to calm down the inflammation and stops a part of the immune response from getting too active.
