Currently, there is a lack of effective biomarkers for early detection and prognostic prediction of CMT. To improve CMT detection, we established a multiplexed immunoassay using a fluorescence bead-based suspension array system to measure serum levels of autoantibodies against four CMT-associated proteins (AGR2, HAPLN1, IGFBP5, and TYMS) in CMT patients. Our data revealed that serum levels of the four autoantibodies (anti-AGR2, anti-HAPLN1, anti-IGFBP5, and anti-TYMS) were significantly elevated in CMT patients (n = 158) compared to healthy individuals (n = 39). Notably, serum levels of anti-AGR2, anti-HAPLN1, and anti-TYMS in the dogs with stage I CMT (n = 56) were higher than those in the healthy group. Using a marker panel consisting of the four autoantibodies for detecting malignant CMT (n = 125) achieved a sensitivity of 50.4% and a specificity of 90%. Furthermore, higher levels of anti-AGR2, anti-HAPLN1, anti-IGFBP5, and anti-TYMS were associated with poorer survival in CMT patients. Collectively, we established a multiplexed immunoassay platform to detect serum autoantibodies and demonstrated that a tailored autoantibody marker panel shows potential clinical applicability for the diagnosis and prognosis of CMT.","PeriodicalId":51207,"journal":{"name":"Veterinary Quarterly","volume":"45 1","pages":"1-12"},"PeriodicalIF":7.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11626869/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142787679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initially, Raman spectral bands (with specificity to certain molecular structures and functional groups) were identified in formalin-fixed samples of mast cell tumors and soft tissue sarcomas, obtained through routine veterinary biopsy submissions. Then, a custom-built Raman macro-imaging system featuring an intensified CCD camera (iXon Ultra 888, Andor, UK), tunable narrow-band Semrock (USA) optical filter compartment was used to map the spectral features at 1437 cm-1 and 1655 cm-1 in ex vivo tissue. This approach enabled wide-field (cm2), rapid (within seconds), and safe (< 400 mW/cm2) imaging conditions, supporting accurate diagnosis of tissue state. The findings indicate that machine learning classifiers - particularly support vector machine (SVM) and decision tree (DT) - effectively distinguished between soft tissue sarcoma, mastocytoma and benign tissues using Raman spectral band imaging data. Additionally, combining Raman macro-imaging with residual near-infrared (NIR) autofluorescence as a bimodal imaging technique enhanced diagnostic performance, reaching 85 - 95% in accuracy, sensitivity, specificity, and precision - even with a single spectral band (1437 cm-1 or 1655 cm-1). In conclusion, the proposed bi-modal imaging is a pioneering method for veterinary oncology science, offering to improve the diagnostic accuracy of malignant tumors.","PeriodicalId":51207,"journal":{"name":"Veterinary Quarterly","volume":"45 1","pages":"1-17"},"PeriodicalIF":7.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143812669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The European hedgehog Erinaceus europaeus is frequently presented in rehabilitation centres and veterinary practices due to health problems, including myiasis. In the present study, 557 hedgehogs presented at wildlife rehabilitation centres in Northern Germany during 2018-2021 were examined for the presence of dipteran eggs and larvae. Overall, 15.6% of animals carried fly eggs and/or larvae. Four different dipteran species were identified by PCR and sequencing of the internal transcribed spacer 2 (ITS-2) region. Lucilia sericata was detected on 25.3% [22/87] of affected hedgehogs, followed by Calliphora vicina (12.6% [11/87]), Lucilia ampullacea (11.5% [10/87]) and Lucilia caesar (9.2% [8/87]). Myiasis prevalence was significantly higher during the summer compared to spring and autumn. Fly eggs were found all over the body, while larvae were detected most frequently in the body's natural orifices and in wounds. Regarding rehabilitation success, myiasis occurred significantly more frequently in animals that died or were euthanized compared to those released back into the wild. Although the high death rate probably arose in combination with underlying disease, this illustrates that myiasis represents a serious health issue that should be diagnosed and treated immediately.","PeriodicalId":51207,"journal":{"name":"Veterinary Quarterly","volume":"45 1","pages":"15-24"},"PeriodicalIF":7.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11812111/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143384015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study utilized multi-distance spatial cluster analysis, kernel density analysis, directional distribution analysis to investigate the spatial distribution patterns of historical FMD epidemics. A multi-algorithm ensemble model considering climatic, geographic, and social factors was developed to predict the suitability area for FMDV, and then risk maps of FMD for each species of livestock were generated in combination with the distribution of livestock. The results show that all serotypes of FMD exhibit significant clustering with a clear tendency toward a directional distribution. Serotypes A and O are widespread in Asia, Europe, Africa, and South America. Serotype Asia 1 is prevalent in Asia. Serotype SAT2 is prevalent in Africa and the Middle East, while Serotypes SAT1 and SAT3 are restricted to Africa. Ecological niche modeling reveals temperature, precipitation, wind speed, and vegetation are important factors influencing the occurrence of FMD. Except for buffaloes, the distribution of high-risk areas for FMD occurrence in other livestock species is quite widespread. The areas primarily include the southern region of North America, the northern, southern, and eastern regions of South America, the Mediterranean region, the eastern region of Europe, the central and southern regions of Africa, the central, eastern, and southern regions of Asia, and parts of Australia.

The results revealed that quercetin ameliorated the aberrant enhancement of body and liver weight. The hepatic histological anomalie induced by MAFLD were also mitigated by quercetin. HFD-induced imbalance in serum LDL, HDL, AST, ALT, TG, and LDH was mitigated by quercetin. Mechanically, we found that quercetin improved lipid metabolism by reducing lipogenesis proteins including ACC, FASN, and SREBP-1c and enhancing β-oxidation proteins including PPARα and CPT1A. In vitro study demonstrated that quercetin regulated hepatic lipid metabolism by targeting SREBP-1c and PPARα. Additionally, quercetin enhanced the antioxidant capacity in HFD-treated mice by downregulating Nrf2 and HO-1 expressions and upregulating SOD and GPX1 expressions. The hyper-activation of inflammation was also restored by quercetin via eliminating the phosphorylation of IκBα and NF-κB p65.

Coccidiosis affects mainly the gut, where parasite proliferation occurs. The intestinal barrier, which consists of chemical, mechanical, biological, and immune defences, plays a crucial role in protecting the host against pathogens, xenobiotics, and toxins present in the gastrointestinal tract. When animals ingest sporulated Eimeria spp. oocysts, these parasites primarily reproduce in the intestinal tract, causing damage to the structure and function of the intestine. This disruption of intestinal homeostasis adversely affects animal health. Numerous studies have also revealed that Eimeria-infected animals experience slower bone growth rates, inferior meat quality, reduced egg production and quality, as well as impaired growth and development. Therefore, the purpose of this review is to examine the underlying mechanisms through which Eimeria spp. regulate intestinal damage and disturb the balance of the internal environment. Specifically, this review will focus on their effects on the structural basis of the host intestine's chemical, mechanical, biological and immune barriers. This understanding is crucial for the development of effective drugs to prevent the invasion of Eimeria spp. into the intestine, which is of paramount importance for maintaining host health.","PeriodicalId":51207,"journal":{"name":"Veterinary Quarterly","volume":"45 1","pages":"1-22"},"PeriodicalIF":7.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11749151/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143015461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
