Lipids are critical nutrients for aquatic animals, and excessive or insufficient lipid intake can lead to physiological disorders, which further affect fish growth health. In the gut microbiota has an important regulatory role in metabolism. However, effects of a high-fat diet on physical health diversity freshwater drum (Aplodinotus grunniens) unclear. Therefore, present study, control group (Con, 6%) (HFD, 12%) were established 16-week feeding experiment explore changes potential mechanisms bacteria. The results indicated that inhibited antioxidant immune capacity while increasing inflammation, apoptosis autophagy cells. Transcriptome analysis revealed significant enrichment immune-related, apoptosis-related disease-related pathways. Through 16S rRNA analysis, total 31 genus-level differentially abundant bacterial taxa identified. addition, reduced microbial disrupted ecological balance (Ace, Chao, Shannon Simpson indices). Integrated combined with indicators transcriptome disorders associated intestinal antioxidants, inflammatory responses, cell autophagy. Specifically, Proteobacteria (Plesiomonas, Arenimonas, Erythrobacter Aquabacteriumb) could serve as targets controlling response high-fat-diet stimulation.

Microbial Interactions in Rearing Systems for Marine Fish Larvae

Microorganisms, Год журнала: 2025, Номер 13(3), С. 539 - 539

This article reviews the scientific literature discussing microbial interactions between water microbiota, live food fish larvae immune system and gut biofilm communities in rearing systems for marine larvae. Fish microbiota is first line of defense against opportunistic pathogens, are vulnerable to high mortalities during weeks after hatching. The bacterial colonization a dynamic process influenced by environmental host-related factors. bacteria transferred from eggs can influence composition early stages fish. ingest free-living microorganisms present water, as drink osmoregulation. In aquaculture systems, conventional feeding–rearing protocol consists zooplankton (rotifers, Artemia, copepods). These organisms filter-feeders. Once new environment, they quickly adopt microflora surrounding water. So, similar at time ingestion biofilms may harbor pathogenic serve reservoir those microbes, which colonize column. methods applied study were reviewed.

Arthropods to Eutherians: A Historical and Contemporary Comparison of Sparse Prenatal Microbial Communities Among Animalia Species

American Journal of Reproductive Immunology, Год журнала: 2024, Номер 92(2)

Since the advent of next-generation sequencing, investigators worldwide have sought to discern whether a functional and biologically or clinically relevant prenatal microbiome exists. One line research has led hypothesis that microbial DNA detected in utero/in ovo prior birth/hatching is result contamination does not belong viable microbes. Many these preliminary evaluations been conducted humans, mice, nonhuman primates due sample specimen availability. However, comprehensive review literature across animal species suggests organisms maintain an obligate relationship with microbes may act as better models for interrogating selective pressures placed on vertical transfer over traditional laboratory species. To date, studies humans viviparous failed illustrate clear presence utero. Until ground truth regarding status relevance can be ascertained, it salient conduct parallel investigations into prevalence developmental lifespan multiple kingdom Animalia. This understanding necessary only determine role vertically transmitted their products early human health but also understand full Health impact. among first compile such primary conclusions from original investigator's conclusions, hence collectively illustrates supported by experimental evidence arising long rigorous scientific history encompassing breadth
