Age matters: exploring differential effects of antimicrobial treatment on gut microbiota of adult and juvenile brown trout (Salmo trutta)

Animal Microbiome, Год журнала: 2025, Номер 7(1)

Abstract Background Antibiotics and antiparasitics are essential tools in controlling infectious disease outbreaks commercial aquaculture. While the negative effects of antimicrobials on gut microbiome various farmed fish species well documented, influence underlying host factors, such as age, responses remains poorly understood. This is especially evident for peracetic acid, whose impact has not yet been studied. Understanding how dynamics vary by age critical to improving antibiotic stewardship In this study, juvenile sexually mature brown trout ( Salmo trutta ) were used a model investigate age-dependent florfenicol acid using 16S rRNA metabarcoding approach. Results Fish significantly shaped taxonomic composition microbial co-occurrence network structure microbiome, regardless treatment. Juvenile exhibited greater volatility stronger response both compared adult fish, with disruptions persisting up 11 days post-treatment. Temporal also evident, shifts characterized decline beneficial commensals like Cetobacterium Lactococcus . Although overall abundance recovered 18 post-treatment, positions key community members remained altered, particularly fish. Opportunistic pathogens, including Aeromonas Streptococcus, enriched assumed more central roles within networks treated Conclusion The initial strongly influenced which turn affects microbiome’s disruption. Juveniles displayed higher susceptibility perturbation, although recovery was observed at level, properties altered. study provides first evidence that external application can disrupt communities. Since compositional often linked functional alterations, even short-term may have important consequences health developing These findings emphasize importance considering relation aquaculture management practices.

Comparative studies on the intestinal health of wild and cultured ricefield eel (Monopterus albus)

Frontiers in Immunology, Год журнала: 2024, Номер 15

Fish intestinal health under intensive aquaculture mode plays an important role in growth, development, and immune function. The present study was aimed to systematically investigate the differences of between wild cultured Monopterus albus by biochemical parameters, histomorphology, molecular biology. A total 15 healthy M. per group, with average body weight 45 g, were sampled analyze parameters. Compared fish, foregut had lower trypsin, lipase, SOD, CAT, T-AOC, GSH-Px activities ( P < 0.05) higher amylase activity MDA content 0.05). villus circumference goblet cells group significantly than those In addition, fish showed relative expression levels occludin , zo-1 zo-2 claudin-12 claudin-15 mucin5 mucin15 lysozyme complement 3 il-10 tgf-β1 tgf-β2 tgf-β3 il-1β il-6 il-8 tnf-a ifnγ mRNA expressions terms gut microbiota, at phylum level displayed percentages Chlamydiae Spirochaetes Firmicutes Bacteroidetes Actinobacteria Cyanobacteria Verrucomicrobia compared At genus level, abundances Pseudomonadaceae_Pseudomonas Spironema Lactococcus Cetobacterium observed To our knowledge, this is first investigation status biochemistry, histology, biology levels.

The impact of nutritional programming on the microbiota of different gut regions in Atlantic Salmon (Salmo salar) from first feeding in a 22-week feeding trial

Increasing evidence suggests that gut microbiota is essential for regulating the development of digestive system, aiding digestion, nutrient metabolism, growth, immune function, and disease resistance. Advances in high throughput sequencing technologies have allowed a broader understanding complex fish, especially relation to impact dietary plant ingredients on health. However, date, most studies focused entire or distal response plant-based diet. Moreover, potential involvement microbiome driving adaptation early-exposed Atlantic salmon diet during later developmental stage, phenomenon commonly referred as ‘nutritional programming’, has yet be demonstrated. The aim was characterise compare composition diversity regions (pyloric caeca, middle intestines) (maintained 22 weeks from first feeding recirculating aquaculture system) with without nutritional programming using 16S rRNA amplicons employed monitor taxa were identified amplicon sequence variants. study experiment followed typical design two experimental groups. Fish initially exposed at challenged 16 post first-feeding six similar considered programmed group, whereas those fed marine control group. alpha higher pyloric caeca than intestine. Analysis similarities showed differentiated each after both low-abundant taxa.
