To investigate the effect of tannic acid (TA) on growth, disease resistance, and intestinal health Chinese soft-shelled turtles, individual turtles were fed with 0 g/kg (CG), 0.5 g/kg, 1 2 4 TA diets for 98 days. Afterwards, turtles’ resistance was tested using Aeromonas hydrophila. The results showed that 0.5–4 dietary increased growth performance feed utilization (p < 0.05), 2.38 being optimal level specific rate (SGR). addition in mucosal fold height submucosa thickness small intestine, which reached a maximum g/kg. 0.5–2 effectively reduced cumulative mortality had been induced by A. hydrophila, dosage leading to lowest mortality. Additionally, 1–4 improved T-SOD, CAT, GSH-Px activities during infection, while enhanced richness diversity microbiota, example, increasing Actinobacteria but inhibiting Firmicutes. transcriptome demonstrated predominant differentially expressed genes (DEGs) TA2 mainly enriched PPAR signaling pathway (Acsl5, Apoa2, Apoa5, Fabp1, Fabp2, Fabp6); glycine, serine, threonine metabolism (Chdh, Gatm, Shmt1); steroid biosynthesis (Cel, Hsd17b7, Soat2, Sqle). main metabolites (DEMs) discovered means metabolome analysis included cholylhistidine, calcipotriol, 13-O-tetradecanoylphorbol 12-acetate, hexahomomethionine CG vs. TA2. Integrative analyses two omics revealed mitigated inflammation activating regulating lipid via multiple pathways, such as α-linolenic metabolism. In general, inclusion turtle can optimally promote bacterial maintaining improving antioxidant capacity.

Chronic chlorothalonil exposure inhibits locomotion and interferes with the gut-liver axis in Pelophylax nigromaculatus tadpoles

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: April 25, 2025

Abstract Chlorothalonil is a widely used fungicide that has negative effect on individual movement, but its impact pathway needs further refinement. Here, the effects of exposure to chlorothalonil locomotion behavior Pelophylax nigromaculatus tadpoles (GS23) were measured at three different levels (0 µg/L, 10 and 50 µg/L), possible pathways analyzed from gut-liver axis. µg/L significantly reduced average speed P. by 26% 32.7%, respectively, decreased locomotor frequency 27.1% 58.6%, respectively. Gut microbiota analysis revealed increased abundance Firmicutes , while Actinobacteriota Pseudomonas Rhodococcus . Metabolomics identified treatment changed amino acid-related metabolism in gut liver altered glycerophospholipid liver. This study indicated can affect abilities interfering with axis aquatic animals. These findings establish compromises organism motility through multi-target mechanism involving modulation, acid metabolic interference, hepatic lipid disruption.

Purpose of the review : analysis effect photoperiodic factor based on indicators lipid metabolism in Salmonid and Cyprinid fish species. Methods used comparative literature own experimental data. Results: The length daylight (photoperiod) is one most important abiotic factors affecting behavior, reproduction, metabolism, growth development fish. changes lipids fatty acid constituents execute a significant role adaptation aquatic organisms to new light conditions. Certain parameters lipidogenesis can serve as reliable indicator normal route metabolic processes organism. It widely known that photoperiod regimes are aquaculture optimize cultivation various species organisms, including common Cyprinids Salmonids. specificity reaction effects lighting modes shown: cyprinids, be multidirectional depending (including its absence), while Salmonids example Atlantic salmon, change profile direction smoltification observed. combining with other factors, such feeding climatic features region, discussed. Significance: results contribute better understanding adaptive conditions for their artificial rearing.
