This was conducted in two steps: a computational prediction study (in silico) and an experimental investigation (in vivo). The prediction step involved molecular docking analysis to assess the interactions between GEN and key stress-related mRNAs in Nile tilapia. In the experimental phase, 160 Nile tilapia fingerlings were randomly assigned to four treatment groups (in four replicates/group) for 60 days: (1) a control group fed a basal diet, (2) a GEN group receiving a GEN-supplemented diet (500 mg/kg), (3) an As group exposed to 10 µg/L As, and (4) an As + GEN group, in which fish was exposed to As and fed the GEN-supplemented diet. The computational assessment of GEN's binding ability revealed strong interactions with key mRNAs associated with inflammation and misfolded protein responses. The in vivo results revealed that GEN significantly alleviated As-induced hepatic oxidative stress and hepatocellular damage by restoring liver enzyme levels, lipid profiles, and bilirubin content and restoring the serum proteins to near-normal values. Additionally, GEN downregulated the expression of endoplasmic reticulum (ER) stress- and inflammation-related genes in the liver tissue of the As + GEN group, compared to the As-exposed fish fed on a basal diet. Additionally, the histopathological analysis further confirmed that GEN supplementation mitigated hepatic tissue damage, reducing necrosis, congestion, and inflammatory cell infiltration. In conclusion, GEN supplementation effectively counteracted As-induced hepatotoxicity in Nile tilapia by modulating oxidative stress, ER stress, and inflammation while preserving liver structure and function. Also, the molecular docking results suggest that GEN interacts with the mRNAs of inflammatory and misfolded protein targets, which are increased due to exposure to As-contaminated water. All our findings highlight GEN as a promising natural dietary additive for improving hepatic health in fish inhabiting As-contaminated environments.</p>","PeriodicalId":23690,"journal":{"name":"Veterinary Research Communications","volume":"49 4","pages":"210"},"PeriodicalIF":1.8,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144152033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study investigated the prevalence and molecular characterization of biofilm-forming S. aureus isolated from goat mastitis, the associated risk factors, and comparative antibiogram profiling. A total of 768 milk samples were conveniently collected from farms dairy goats in three districts of Pakistan Multan, Bahawalpur, and Rahim Yar Khan. The results revealed a molecular prevalence (presence of nuc gene) of 206/426 (48.37%) for S. aureus in milk samples from goats. The risk factors analysis showed that age group, water availability, previous mastitis history, hygienic measures during milking, teat lesion, and veterinary services posed significant associations with S. aureus intramammary infections in goats. The prevalence of biofilm production by phenotypic methods i.e. Congo Red agar and Microtitre plate were recorded to be 36.90% and 27.67% respectively. In comparison, the genotypic confirmation was done by the presence of the icaA gene and was found to be 55.34%. The phylogenetic analysis of the icaA gene revealed high homology between sequences of study isolates and the isolates of other countries like India, Egypt, Japan Kenya, the USA, and China. The S. aureus subjected to the Kirby-Bauer disc diffusion method revealed the highest resistance to cefoxitin and oxytetracycline followed by gentamycin, amikacin, trimethoprim + sulphamethoxazole, and vancomycin. There was a slight variation among the resistant profile of biofilm and non-biofilm producing S. aureus strains against antimicrobial agents. Out of 206, 31.07% (64/206) tested isolates exhibited resistance to three or more antibiotics concurrently, categorizing them as multiple drug resistant (MDR) with multiple antibiotic resistance index greater than 0.2.

Within 24 h after tiamulin treatment, feed and water consumption declined drastically, and mortality increased progressively, reaching a peak of 1.75%. Cumulative mortality over a 13-day period was 4.3%. Affected pullets (8%) exhibited marked apathy, muscle weakness, flaccid paralysis, and prostration. Necropsy of 18 naturally dead pullets revealed gross myocardial (72%) and vastus intermedius (100%) muscle pallor, with histopathological examination confirming monophasic myocardial and myocyte degeneration and necrosis (100%). Fibrosis and granulomatous infiltration surrounding and infiltrating affected muscle fibers were observed in a low number of animals (11%). These findings suggest that tiamulin enhances monensin toxicity through biochemical interactions, indicating that the combination of 150 ppm tiamulin and 120 ppm monensin is highly toxic to pullets.
