This study aims to investigate the individual profile of Portuguese veterinary practitioners, their knowledge about this type of therapy and their interest in its future use and application. This questionnaire-based descriptive study was carried out in Portugal from November 2021 to January 2022. A questionnaire-based survey was conducted online, using an electronic platform. The following topics were surveyed: (i) profile of veterinarians; (ii) knowledge about cell therapies; and (iii) interest in future use and application. After an internal validation, the survey was released online for three months in Portuguese veterinary social network groups. Data were collected and descriptive analysis and Chi-square test were performed. A total of 275 responses were obtained and analysed. Analysis of the results showed that the participating veterinarians know what mesenchymal stromal cells (MSCs) are (90.9%) and are generally aware of their therapeutic potential (94.5%). Regarding their use, 56.7% of the respondents do not know their application in veterinary pathologies. The remaining 43.3% indicated the situations in which they knew of its use. Orthopaedic and dental or oral diseases were the most frequently mentioned. Regarding the immunological effect of MSCs, there is a great lack of information. Data analysis showed that 72.4% of respondents were unaware of the possibility of an immunogenic response following their administration. However, 53.5% stated that they were aware of the positive immunomodulatory capacity. Most professionals who participated in this survey consider this topic relevant in veterinary medicine (95.6%), as well as the existence of this type of service in the national territory (96.4%). The great interest shown by 96.7% of the respondents in learning more about the subject highlights the importance of raising awareness, conducting further studies and promoting knowledge sharing in their daily clinical practice and research. The relationship between the national status of stem-cell therapy and veterinarians' knowledge is influenced by limited regulation but growing professional interest and driven by private companies and professional organisations. This study contributes to a better understanding of the trends related to this topic in the context of veterinary practice in Portugal.</p>","PeriodicalId":9041,"journal":{"name":"BMC Veterinary Research","volume":"21 1","pages":"487"},"PeriodicalIF":2.6,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12288361/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144697549","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}

The control group (Control) received a basal diet, while the antibiotic-treated group was supplemented with 2 g/kg chlortetracycline hydrochloride (CTC) as a positive control.

The current study aimed to investigate molecular identification, cyst histological examination and seroprevalence of Sarcocystis spp. in water buffaloes slaughtered in the main abattoirs of 6 Egyptian Governorates; Cairo, Giza, Beni-suef, Al-Sharqia, Qalyubia, and El-Beheira. Each buffalo was visually inspected for the presence of Sarcocystis macrocysts and blood samples were collected. Out of 900 examined water buffaloes (Bubalus bubalis), 246 (27.3%) were found to be infected based on macroscopic examination. Histological examination of the macrocyst revealed metrocytes close to the cyst's edge and elongated curving basophilic bradyzoites occupying most of the cyst. Depending on age, we categorized naturally infected buffaloes into 3 groups: young (< 2 y.), adult (2-5 y.) and old (5-10 y.). The highest infection rate was observed in older buffaloes aged 5-10 years, meanwhile female animals exhibited a higher prevalence of infection compared to males. The esophagus had the highest presence of Sarcocystis compared to other organs. Using PCR based on 18S rRNA gene and sequencing, we isolated 3 Sarcocystis species from infected tissues: S. buffalonis, S. fusiformis and S. hirsuta-like. The prepared whole cyst antigen of S. fusiformis was characterized by 9 major polypeptides (140, 120, 78, 66, 53, 39, 32, 24 and 19 kDa) on 10% SDS-PAGE. Using western blotting, we identified 2 common immunogenic reactive bands (66 and 32 kDa) against naturally infected buffalo sera and hyperimmune rat sera. Additionally, sarcocystosis positive seroprevalence rate was 46.4% (418/900) with a sensitivity of 97.6% and specificity of 100% using indirect ELISA based on S. fusiformis whole cyst antigen. In conclusion, this study highlights the molecular identification, cyst histological examination and seroprevalence of Sarcocystis sp. among buffaloes in Egypt. ELISA using the S. fusiformis whole cyst antigen could be adapted to detect antibodies to Sarcocystis sp., in live animals, with an acceptable specificity and sensitivity.</p>","PeriodicalId":9041,"journal":{"name":"BMC Veterinary Research","volume":"21 1","pages":"482"},"PeriodicalIF":2.6,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12281994/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144688876","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}

Current production systems wean piglets at a relatively young age, and it is unclear if age at weaning impacts shifts in intestinal immune populations, particularly intraepithelial T lymphocyte (T-IEL) populations, or bacterial communities, in a comparable timeframe and magnitude. T-IELs reside in the intestinal epithelium and play a role in intestinal integrity and defense. While later weaning may be an approach to minimize the negative impacts of weaning, the impact of age at weaning on T-IEL abundances and function is not clearly understood. Our results indicate pigs weaned at 18-21 days of age (doa; standard weaned, SW), which is consistent with production practices in the United States, had delayed shifts in T-IEL populations when compared to pigs weaned at 25-28 doa (late weaned, LW), which is consistent with practices in the European Union. Specifically, the abundance of induced T-IELs (CD8αβ<sup>+</sup> αβ T cells) in the jejunum increased between 0 and 3 days post-weaning (dpw) for the LW group and stabilized, but shifts were delayed until between 3 and 7dpw in the SW group. Concomitant decreases in the abundance of natural T-IEL (γδ T cells) were detected. The structure of jejunal mucosal bacterial communities were comparable between SW and LW pigs at 0dpw, but the SW group had more pronounced shifts from 3 to 7dpw and 7dpw to 14dpw compared to minimal shift in LW group from 7 to 14dpw. Body weight between groups was comparable when adjusted for age. Overall, the bacterial communities of the jejunal mucosa were more stable after weaning in LW than SW pigs, and jejunal T-IEL abundances stabilized more rapidly in the LW group. As T-IELs play a key role in intestinal homeostasis and barrier integrity, the early differences in population abundance may be indicative of functional differences as well.</p>","PeriodicalId":9041,"journal":{"name":"BMC Veterinary Research","volume":"21 1","pages":"477"},"PeriodicalIF":2.3,"publicationDate":"2025-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12275383/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144667070","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}
