Abstract The aim of this study was to evaluate the phytobiotic potential oils from Copaifera langsdorffii (copaiba), Carapa guianensis (andiroba), Attalea speciosa (babassu), Mauritia flexuosa (buriti), and Caryocar brasiliense (pequi), as well two types aqueous extracts Terminalia catappa (tropical almond), alternatives antibiotics containing enrofloxacin or oxytetracycline active ingredients in continental aquaculture. Five species-specific pathogens with high prevalence dissemination fish farming systems were selected for study. virulence strains assessed using Gram staining, catalase, hemolytic activity tests, followed by inhibition halo assays potential. All exhibited vitro subjected evaluations, where inhibitory zones tested products measured, along their bactericidal bacteriostatic effects. Among evaluated products, only A. did not exhibit an against analyzed pathogens. Conversely, C. brasiliense, M. flexuosa, guianensis, langsdorffii, hot extract T. demonstrated effects, yielding superior results (P > 0.05) compared positive control oxytetracycline. proved be competitive ingredients, showing antibacterial action Aeromonas hydrophila, caviae, jandaei, Streptococcus agalactiae.

Recently, the prevalence of Aeromonas hydrophila antibiotic-resistant strains has been reported in aquaculture, but its intrinsic antibiotic resistance mechanisms are largely unknown. In present study, a label-free proteomics technology was used to compare differential protein abundances response norfloxacin (NOR) stress A. hydrophila. The results showed that there were 186 proteins decreasing and 220 increasing NOR stress. Bioinformatics analysis differentially expressed enriched several biological processes, such as sulfur metabolism homologous recombination. Furthermore, sensitivity assays deletion AHA_0904, cirA, cysI significantly decreased against NOR, whereas ΔAHA_1239, ΔcysA, ΔcysD, ΔcysN increased NOR. Our provide insights into indicate AHA_1239, may play important roles

Herbal extracts have been considered as ideal alternative to antibiotics in aquaculture and application of combinatory effective always can exhibit the enhanced bioactivity with high efficiency. In our study, a novel herbal extract combination GF-7, which is composed Galla Chinensis, Mangosteen Shell well parts Pomegranate peel Scutellaria baicalensis Georgi extracts, was prepared applied for therapy bacterial infection aquaculture. The HPLC analysis GF-7 also investigated quality control chemical identification. bioassay, had excellent antibacterial activity against various aquatic pathogenic bacteria vitro, related MIC values were between 0.045 0.36 mg/mL. After feeding Micropterus salmoide (0.1, 0.3, 0.6%, respectively) 28 days, activities ACP, AKP, LZM, SOD, CAT liver each treatment group significantly increased content MDA decreased. Meanwhile, hepatic expression immune regulators including IL-1β, TNF-α, Myd88 at different times up-regulated varying degrees. challenge results exhibited good dose-dependent protective effect on M. salmoides infected A. hydrophila, further confirmed by histopathology. Our imply that potential natural medicine prevention numerous infectious diseases

Abstract Yersiniosis or enteric redmouth (ERM) is responsible for significant mortalities among rainbow trout and other salmonids. Hence, its prevention and/or control has become a research hotspot. Antibiotics are effective control; however, accumulating evidence indicates that unrestricted use of antibiotics harms fish, human beings, the environment. Thus, finding safe, efficacious, cost-effective, environmentally friendly substitutes great interest. Reports showed dietary supplementation with functional additives health-promoting immunostimulatory functions could be promising strategy. Herein, we provide an overview non-antibiotic feed-based strategies combating EMR in without resorting to antibiotic usage. For this issue, uses application some vitamins, probiotics, prebiotics, synbiotics, quorum quenching probiotic strains, algae, organic acids, included article. The roles phytobiotics (herbal supplements), their phytochemicals, essential oils extracted from them will also elucidated. Some emerging nano-based feed supplements discussed. Considering advantages, literature declared these enhance overall health condition, haemato-immunity, disease resistance conferred high protection experimentally infected yersiniosis. Given perspective, article presents current situation latest knowledge on supplements, emphasizing not only support immunity decrease effects but minimize usage aquaculture. Limitations future perspectives effectiveness efficacy This review help aquaculture sustainability improve welfare trout.
