Rutin, a natural flavonoid extract from plants, exhibits antioxidant and anti-inflammatory properties, alongside a protective impact on the intestinal tract of pigs. However its influence on the proliferation, migration, and cellular junctions of IPEC-J2 cells remains unexplored. This study involved treating IPEC-J2 cells with varying concentrations of rutin. It was observed that after 24 h of treatment with 200 µM rutin, cell viability was significantly increased, along with significant upregulation in the mRNA expression levels of proliferation-related genes (CCNE2, CDK4, CDK2, CCNDB, and PCNA) and tight junction genes (ZO-1, Occludin, and Claudin-1). Additionally, the expression of proliferation-related PCNA protein was significantly increased. Transcriptome sequencing revealed that rutin treatment impacted the overall transcription profile of IPEC-J2 cells, altering the expression of genes involved in critical physiological processes such as redox balance, cell proliferation, and tight junctions maintenance. Consequently, rutin demonstrated a significant enhancement in the proliferation of IPEC-J2 cells and improved the intestinal barrier function in pigs, offering valuable insights for sustaining pig intestinal health in swine husbandry.","PeriodicalId":23690,"journal":{"name":"Veterinary Research Communications","volume":"49 5","pages":"281"},"PeriodicalIF":2.0,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144856554","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}

Mycoplasma spp. Infections have been detected in a variety of wild and captive bird species worldwide. The present work aimed to study the prevalence of Mycoplasma spp. in wild and captive birds in Egypt; a total of 250 birds were examined, representing 15 species (11 orders) of wild birds. The collected samples include 100 tracheal swabs from wild birds and 150 from captive birds. Mycoplasmas were detected using microbiological culture methods. PCR amplification of the 16S rRNA gene was performed for genus-specific identification of mycoplasmas, using universal primers for genus Mycoplasma. Selected PCR products were sequenced for phylogenetic analysis. M. gallisepticum and M. synoviae were also detected by specific PCRs targeting the 16S rRNA gene. Regarding the obtained result, 38/250 positive samples were obtained for the isolation of Mycoplasma spp., with a prevalence of 15.2%. Moreover, confirmation with PCR tests using GPO primers and DNA extracted from the isolates resulted in 22/250 (8.8%) positive samples, which came from birds that belonged to six orders, where the highest occurrence was in Galliformes, followed by Strigiformes, Columbiformes, Accipitriformes, Bucerotiformes, and Ciconiiformes, respectively. Four tested birds were positive for Mycoplasma gallisepticum (M. gallisepticum), and one was positive for Mycoplasma synoviae (M. synoviae). M. gallisepticum and M. synoviae were only detected in two orders (Accipitriformes and Galliformes). The phylogenetic analysis revealed a high variability of Mycoplasma spp. and strong similarities between the studied Egyptian strains and other reference strains available in GenBank.","PeriodicalId":23690,"journal":{"name":"Veterinary Research Communications","volume":"49 5","pages":"280"},"PeriodicalIF":2.0,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12350449/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144837998","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 August and October 2024, 21 cats presented with flaccid tetraparesis and were clinically evaluated. The course of the clinical signs varied from acute to subacute, with signs including hypotonia of all limbs, bladder and intestines, hypophonia, and flaccid paralysis of masticatory muscles. Eight cats died due to cardiorespiratory arrest. Necropsy and histopathological analyses revealed no significant macroscopic or microscopic lesions. Botulinum toxin type C was detected in five cats through standard mouse bioassay: in feces (n = 3), liver (n = 1), and intestinal contents (n = 1). Although the toxin was not found in the remaining animals, botulism was not excluded based on clinical and epidemiological findings, absence of spinal or other neurological lesions, and the exclusion of other infectious agents. All cats tested negative for FeLV, Coronavirus, Toxoplasma gondii, and Neospora caninum, and were also screened for intestinal parasites. Despite the strong epidemiological evidence, including common exposure to commercial diets, hunting behavior, and outdoor access, the source of intoxication was not identified. This study highlights a rare and severe outbreak of feline botulism and reinforces the importance of considering this diagnosis in similar clinical scenarios.","PeriodicalId":23690,"journal":{"name":"Veterinary Research Communications","volume":"49 5","pages":"279"},"PeriodicalIF":2.0,"publicationDate":"2025-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144804954","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}

The complex and intricate ecology of bat viromes results largely from species diversity, roosting patterns, social structures, immunological adaptations, and their remarkable longevity, especially compared to other small mammals such as rodents. These traits allow bats to carry pathogenic viruses without visible clinical symptoms over extended periods. This review delves into the virome of bat populations focusing on major families like Coronaviridae, Filoviridae, Paramyxoviridae and the evolutionary processes leading to their diversity, persistence within populations, and spill-over. The human-induced environmental disturbance in the form of deforestation, cultivation, urbanization, and wildlife trade has increased direct or indirect contact among bats, humans, and domestic animals, increasing the chances of spill-over. The study of historical events in the form of SARS, MERS, Nipah, Ebola is used for practical implications. We also discuss the behavioral and seasonal variations among intra-colony transmission, the role of intermediate hosts, and the critical need of having an effective One Health-based surveillance system. The understanding of ecological and evolutionary drives behind bat virome is necessary for anticipating zoonotic spill-over events, which can be used as a foundation for public health strategies. Finally, the necessity of integrating virology, ecology, and global health policy perspective in human health policy-making is also discussed, in the context of bat virome research, to prevent future pandemics.","PeriodicalId":23690,"journal":{"name":"Veterinary Research Communications","volume":"49 5","pages":"275"},"PeriodicalIF":2.0,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144800418","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}

However, due to the challenges associated with isolation, there remains a scarcity of relevant clinical isolates and genomic information. Here, we isolated two P. bifermentans strains PB29 and PB30 from the fecal samples of Hu sheep, characterized the virulence phenotypes, and conducted a comparative genomic analysis to illustrate the evolutionary pathway and distribution of carbohydrate active enzymes (CAZymes). The results indicated that both isolates exhibited substantial phospholipase C and hemolytic activities, while sharing a close phylogenetic relationship. Moreover, strains of P. bifermentans belonging to the same evolutionary lineage as PB29 and PB30 harbor a greater number of virulence factors than strains from other lineages, with the majority originating from the intestine environment. This observation suggests that this lineage has the potential to clonally spread within the gut and evolve into a representative pathogen. Furthermore, P. bifermentans commonly shares mucin degradation carbohydrate hydrolases (GHs) GH2, GH20, and GH73. They also exhibit conserved CAZymes, such as GT4, GT5, CE4, and CE5, which enable them to efficiently metabolize complex carbohydrates and adapt to diverse ecological niches. Overall, these findings offer valuable genomic insights into the potential role of P. bifermentans as an intestinal pathogen.","PeriodicalId":23690,"journal":{"name":"Veterinary Research Communications","volume":"49 5","pages":"276"},"PeriodicalIF":2.0,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144800415","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}
