To understand the reasons for continued FMD outbreaks in Uganda, a systematic review was conducted to examine FMD epidemiology, control strategies, and related challenges. Literature searches were performed in PubMed, ScienceDirect, Scopus, and Web of Science databases for the period 1958-2022, following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Additionally, FMD reports for the same period were retrieved from the World Reference Laboratories for FMD and the World Organization for Animal Health/Food and Agriculture Organization FMD Laboratories Network websites. A total of 62 documents (26 studies and 36 reports) were eligible for analysis. Results showed that Uganda experienced 17 to 37 FMD outbreaks annually. Most of the studies focused on cattle (n = 20), with few targeting African buffalo (n = 3) and small ruminants (n = 2). The reports revealed that serotype O was the most isolated, followed by A, SAT 1, SAT 2, and SAT 3. FMD clustering was observed near international borders with Kenya and Tanzania and around Queen Elizabeth National Park. Identified risk factors included dry season, animal movements, proximity to borders, and pastoralism. The key control challenges included limited diagnostic capacity, FMD virus diversity, vaccine mismatch, and low vaccination coverage. The findings highlight the need for enhanced FMD monitoring, surveillance, and control strategies that consider circulating serotypes and topotypes, and improvement in vaccination coverage and strengthening of diagnostic capacity. Further research is needed to address the epidemiology of FMD in understudied species, including small ruminants, swine, and wildlife.</p>","PeriodicalId":23690,"journal":{"name":"Veterinary Research Communications","volume":"49 4","pages":"227"},"PeriodicalIF":1.8,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12170765/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144302976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Between 2017 and 2022, 15 passerines were sent to the Veterinary School of the Universidade Federal de Minas Gerais for post mortem examination, as well as fixed tissue samples for histopathological analysis.

Portulaca oleracea is known for its antioxidant and anti-inflammatory activities; yet, its defensive role against Cd²⁺-induced hepatotoxicity in Nile tilapia (Oreochromis niloticus) is still unclear. The current study evaluated the possible hepatoprotective effects of purslane leaf powder (PR) against Cd²⁺-induced liver damage and its mechanisms. A hepatotoxicity model was established by exposing tilapia to Cd²⁺ (50 µg/L) for 60 days, with and without PR supplementation (10 g PR/kg diet). Histopathological analysis, biochemical assays, and real-time quantitative PCR were done to assess liver tissue damage, oxidative stress markers, lipid profile, and inflammatory gene expression. Results showed that Cd²⁺ exposure induced severe hepatic alterations, including glycogen depletion, steatosis, necrosis, and inflammatory infiltration, along with increased liver indices and obvious dyslipidemia. PR supplementation significantly alleviated these changes by reducing oxidative stress, enhancing antioxidant enzyme activity, upregulating antioxidant genes (sod-1, sod-2, cat, gpx, and cyp1a), and downregulating inflammatory markers (mapk1, nf-κb, il1β, il6, il8, and tnf-α). Additionally, PR improved lipid profile and liver morphology, and reduced hepatocyte damage compared to the Cd²⁺-exposed group. In conclusion, PRP mitigates Cd²⁺-induced hepatotoxicity in Nile tilapia by enhancing antioxidant defenses and reducing inflammation, suggesting its potential as a dietary supplement to counteract heavy metal toxicity in aquaculture.</p>","PeriodicalId":23690,"journal":{"name":"Veterinary Research Communications","volume":"49 4","pages":"223"},"PeriodicalIF":1.8,"publicationDate":"2025-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144286626","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}

In this study, the effectiveness of a Montanide^® ISA 206 adjuvanted killed trivalent vaccine containing endemic local strains (TR-21 [BVDV-1l], TR-26 [BVDV-1f], and TR-15 [BVDV-2b]) isolated from Türkiye, was evaluated with a cattle challenge study. Experimental groups were designed as single dose vaccination (Group-I, n:11), two dose vaccination (Group-II, n:11), and unvaccinated (Group-III, n:6) with male calves aged about 6 months. Following the immunization, challenge virus (TR-72 [BVDV-1l], TCID₅₀ 10^6.5) was given intranasally to each group (5 animals in Group-I and II and 4 animals in Group-III), and clinical findings, hematological changes, virus shedding, side effects, and viremia were monitored for 14 days after inoculation. Serological monitoring of the remaining animals against homologous and heterologous strains was carried out at one-month intervals between the 21st and 201st days after the first vaccination. The obtained results showed that the viremia, hematological changes, and clinical findings shown in unvaccinated animals (Group-III) were significantly suppressed (p < 0.05) in the vaccinated groups (Group-I and II). In addition, it was found that serologically monitored animals maintained protective neutralizing antibody (nAb) titers ≥ 8 log₂ for vaccinal and also for all reference BVDV-1 strains, which is more than three-fold protective antibody response, lasting more than 7 months after the first vaccination, whether in single or two dose application. The rise of nAbs was also detected for heterogous BVDV strains. The detected nAb titers were significantly higher (p < 0.05) in the two dose vaccination group.

In the Wi-Fi group, we also noted a significantly increased number of apoptotic and proliferating cells as well as a significant up-regulation of caspase-1 gene expression.
