Duck hepatitis A virus serotype 3 (DHAV-3), duck Tembusu virus (DTMUV) and novel duck reovirus (NDRV), belonging to the family Picornaviridae, Flaviviridae and Spinareoviridae, respectively, are important pathogens with similar symptoms in infected ducks. To detect and differentiate these viruses, this study developed a triplex real-time PCR assay targeting the VP1, E and σC genes of DHAV-3, DTMUV and NDRV, respectively. Validation tests and clinical applications followed the optimization of the triplex real-time PCR assay. The novel triplex assay showed high specificity with no cross-reactivity with eight other common duck viruses. The detection limits were 1 × 101 copies/μL for DTMUV, DHAV-3 and NDRV, with intra- and inter-assay variation coefficients (CV) below 4%. A total of 135 clinical samples were tested to evaluate the method's feasibility. The positive rates for DHAV-3, DTMUV and NDRV were 13.33%, 10.37% and 8.15%, respectively. Using virus isolation as a reference, the triplex qPCR assay showed 100% detection sensitivity for all three viruses, with specificity and coincidence values above 97%. In conclusion, the established triplex TaqMan PCR is highly specific, sensitive and reproducible, providing a practical approach for detecting and monitoring DHAV-3, DTMUV and NDRV in ducks.","PeriodicalId":7247,"journal":{"name":"Acta veterinaria Hungarica","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144648266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Samples were collected from 11 turkeys (from 4 flocks) and 9 pheasants (from 3 farm-raised flocks) suspected to have histomonosis. These samples were molecularly and phylogenetically analysed. In nine turkeys, five 18S rRNA genes and two ITS sequence variants of Histomonas meleagridis were identified. These variants were identical between the caecum and liver of the same bird in most cases, but different 18S variants were identified between sampling sites. In one turkey, an unnamed species, here designated as \"Dientamoebidae sp. HUN35\", was identified. Its 18S rRNA gene sequence was near-identical (99.6-99.3%) to the sequence reported previously; and the ITS-1/5.8S/ITS-2 region confirmed a close relationship with H. meleagridis and Dientamoeba fragilis. In one pheasant, Tetratrichomonas gallinarum was detected. Different 18S rRNA variants had either identical or different ITS sequences, thus optimally, both should be used for molecular epidemiological studies. Our results suggest the unnamed Dientamoebidae sp. has been present in Hungary since its first detection in 2010 and the host range of this species as well as that of T. gallinarum is broader than previously thought.","PeriodicalId":7247,"journal":{"name":"Acta veterinaria Hungarica","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144648265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Positive samples were further assessed using the McMaster technique to determine eggs per gram.

Season, age and breed showed no effect on significant effect on prevalence, while sex and body condition had a significant impact. Trematode prevalence also varied between districts. EPG values ranged from 0 to 300, with a mean of 151.563 ± 8.181.

This study aimed to investigate the therapeutic effects of ursodeoxycholic acid (UDCA) - a secondary bile acid, a byproduct of intestinal bacteria with potent antioxidant properties - against PTX-induced liver injury. PTX was administered intraperitoneally at 2 mg*kg-1 for 5 days to induce liver damage. Rats in the first treatment group received UDCA orally at 60 mg*kg-1 for fifteen days, while the second group received the same dose for ten days. Serum levels of AST, ALT, ALP, LDH, total protein, and albumin were analysed using an autoanalyzer. Liver tissue was assessed for total oxidative status (TOS), oxidative stress index (OSI) and total antioxidant status (TAS). Histopathological and immunohistochemical analyses were also conducted. UDCA administration ameliorated PTX-induced changes in bodyweight and liver enzymes. It reduced necrosis, hydropic degeneration and mononuclear cell infiltration in liver tissue. UDCA also significantly decreased TOS and OSI levels, alleviating oxidative stress, and increased TAS. Furthermore, UDCA reduced DNA damage, evidenced by lower 8-OHdG immunoreactivity, and regulated autophagy and apoptosis by reversing elevated LC3B and cleaved caspase-3 levels. These findings suggest that UDCA may offer therapeutic benefits against PTX-induced hepatotoxicity.","PeriodicalId":7247,"journal":{"name":"Acta veterinaria Hungarica","volume":" ","pages":"86-96"},"PeriodicalIF":0.7,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143959604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Histopathological examination revealed a poorly demarcated tumour located in the mucosa. Non-pigmented neoplastic cells with marked anisocytosis, anisokaryosis, increased nuclear-cytoplasmic ratio and numerous mitotic figures formed solid packets separated by collagenous septa. IHC analysis revealed that tumour cells were positive to melan-A, S100 protein, neuron-specific enolase and cytokeratins AE1/AE3. Based on the histopathological and IHC findings, the tumour was diagnosed as a non-pigmented chromatophoroma.
