This research aimed to assess efficacy of the NewFluRazi vaccine to in protecting against Newcastle disease. In the study, 90 specific pathogen-free (SPF) chickens, 21 days old, were randomly divided into five groups-four groups were vaccinated while one group remained unvaccinated. At 42 days of age, all birds in the four vaccinated groups and the control group were exposed to a highly virulent genotype VII strain of the virus circulating locally. Hem-agglutination inhibition test was performed against the antigen on day 42 to assess immunogenicity. For pathological analysis, tissue samples were collected on days 3, 5 and 7 post-challenge. Lung, trachea, cecal-tonsil and spleen tissues were collected and analysed using real-time PCR on days 3, 5 and 7 post-challenge to detect the presence of the virus. The findings revealed that antibody titers increased in all groups 21 days' post-vaccination. Antibody levels in the NewFluRazi and the international bivalent groups were higher than in the national bivalent vaccine group with mean titers of 5.2, 5.2, and 5, respectively. Pathological assessment following the challenge showed no significant difference in the mean lesion scores between the groups. Viral gene expression in the tissues was significantly lower in the NewFluRazi vaccine group compared to the international bivalent vaccine group. For instance, on day 5 post-challenge, the mean CT value for the tissues in the NewFluRazi group was 34.12, whereas it was 22.08 in the international bivalent vaccine group. Overall, our results indicate that the NewFluRazi vaccine was more effective than the international bivalent vaccine in reducing viral presence in the target tissues following challenge.</p>","PeriodicalId":7247,"journal":{"name":"Acta veterinaria Hungarica","volume":" ","pages":"267-272"},"PeriodicalIF":1.0,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148863033","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}

Blood-based biomarkers, especially erythrocyte fatty acid composition, provide an integrated measure of long-term ω-3 FA exposure and are less susceptible to short-term dietary fluctuations than plasma indices. Within this framework, the Omega-3 Index (O3I) - the sum of 2 prominent long-chain ω3 fatty acids (EPA and DHA) in erythrocyte membranes, expressed as a percentage of total erythrocyte FAs - offers a standardised, biologically anchored metric of ω-3 FA status with potential relevance for clinical evaluation and monitoring. Studies in healthy dogs demonstrate low baseline O3I levels, while dietary supplementation with marine-derived ω-3 FAs reliably increases both circulating plasma concentrations and erythrocyte-based indices of ω-3 FA status. In dogs with chronic diseases such as osteoarthritis, cardiac diseases, and selected gastrointestinal disorders, reduced ω-3 FA status is observed and supplementation results in measurable biochemical changes (lower content of triglyceride and total cholesterol, better antioxidant status, reduced production of prostaglandin E2 and interleukin-6). In contrast, comparable erythrocyte-based data are very limited in canine dermatology. Although species-specific reference ranges and outcome-based targets are not yet established, assessment of ω-3 FA status offers a promising tool for monitoring FA supply, guiding supplementation and supporting individualised clinical nutritional management in canine practice.</p>","PeriodicalId":7247,"journal":{"name":"Acta veterinaria Hungarica","volume":" ","pages":"242-246"},"PeriodicalIF":1.0,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148817119","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}

This study, conducted from June to December 2024, analysed 71 PCR-confirmed cases of staphylococcal pyoderma to investigate epidemiological and host-associated risk factors and antimicrobial resistance (AMR) patterns. Bacterial isolates from PCR-positive samples were identified using MALDI-TOF MS and tested for antimicrobial susceptibility. Of the cases analysed, 63.38% involved monomicrobial infections, whereas 36.62% were accounted for polymicrobial infections. Staphylococcus pseudintermedius and Staphylococcus aureus were the predominant pathogens in both infection types, occurring alone or in combination with Escherichia coli, Pseudomonas aeruginosa or Klebsiella pneumoniae. Polymicrobial infections were significantly associated with recurrent disease, longer disease duration, tissue invasion and allergic skin manifestations. Both major Staphylococcus species exhibited high resistance to β-lactams and third-generation cephalosporins, with notable interspecies differences in resistance to ceftizoxime, trimethoprim-sulfonamide, amikacin, enrofloxacin and clindamycin. Although overall AMR did not differ significantly between major staphylococci species associated to monomicrobial and polymicrobial infections, however isolates from polymicrobial cases showed a consistent trend toward higher resistance across multiple antimicrobial classes. The findings emphasise the complexity of canine pyoderma characterised by bacterial communities dominated by Staphylococcus pseudintermedius and the increasingly relevant Staphylococcus aureus with potential zoonotic implications.
