In this study, a recombinant Sendai virus (SeV) vector encoding the SRLV gag-P25 gene (rSeV-GFP-P25) from the EV1 strain was generated using In-FUSION cloning and rescued using the SeV reverse genetic system. Transgene expression and stimulation of innate immunity and interferon-stimulated genes (ovine A3Z1, OBST2 and SAMHD1) were evaluated in ovine skin fibroblasts (OSF) transduced with SeV-GFP and rSeV-GFP-P25. Additionally, to characterize the effect of the SRLV restriction in transduced OSF, the SRLV DNA load was quantified at different times post-transduction and post-infection with strain EV1. Using immunohistochemistry and image analysis, transgene expression and tissue distribution of recombinant P25 were studied in two lambs inoculated intranasally, one with rSeV-GFP-P25 and the other with SeV-GFP. rSeV-GFP-P25 induced efficient and transient transgene expression in vitro and in vivo. Furthermore, OSF transduced with rSeV-GFP-P25 presented upregulation of TLR2, TLR3, TLR6, TLR7, RIG-I, MyD88 and IFN-β, whereas SeV-GFP did not induce TLR6 or IFN-β upregulation. Among the interferon-stimulated genes, OBST2 was significantly upregulated after transduction with rSeV-GFP-P25 compared with the empty vector. SRLV restriction gradually increased and persisted after transduction with SeV-GFP and rSeV-GFP-P25, with OSF transduced three times showing cumulative restriction. Forty-eight hours post-inoculation in vivo, marked P25 expression was observed in ciliated epithelial cells and submucosal macrophages/dendritic cells of the nasal mucosa.

Porcine beta-defensin 2 (PBD-2) is an endogenous antimicrobial peptide produced by pigs.

Additionally, given its strong ability to repair intestinal epithelial damage and maintain intestinal mucosal barrier function, porcine interleukin-22 (PIL-22) is a potential feed additive to combat intestinal damage caused by intestinal pathogens in piglets. In this study, the amino acid sequences of PBD-2 and PIL-22 were combined to express the fusion protein in Pichia pastoris, and its biological activity was evaluated in vitro. Our results showed that the PIL22-PBD-2 exhibits broad-spectrum antibacterial activity against multidrug-resistant enterotoxigenic Escherichia coli O8 (ETEC O8), Escherichia coli (E. coli), Salmonella typhimurium, and Staphylococcus aureus (S. aureus). PIL22-PBD-2 demonstrated wound repair capability through a healing assay in the intestinal porcine epithelial cell line-J2 (IPEC-J2).

However, these features have been observed only in infection experiments, lacking information from the field. In this study, for the first time, we provide evidence for frequent PPR virus exposure in pigs, detected in Nigeria.

The apparent seroprevalence in pigs of 4.24% (95% CI 2.6-6.5 at the population level) distributed across Nigeria provides evidence that PPR infections in pigs are not rare events.

CEV, the causative agent of Koi Sleepy Disease (KSD), can cause high mortality rates and has been reported in many countries and is often linked to the fish trade. The virus is typically detected through DNA analysis of gill tissues, where the highest viral loads are found. However, traditional sampling methods, such as gill sampling, are lethal, complicating routine surveillance, particularly in asymptomatic or high-value koi. This study aimed to evaluate nonlethal sampling methods for CEV surveillance in the koi trade. We analysed various shipping environment samples, such as shipping water and fish bag swabs, alongside gill swabs from anaesthetised fish and gills from naturally deceased fish. Using qPCR, we found that the sensitivity of environmental samples, particularly shipping water, was greater than that of direct fish samples. Latent class modelling estimated that the sensitivity associated with 1.5 mL shipping water samples was greater than 89%, making them a reliable alternative for early detection. All detected variants belonged to genogroup II. Some post-import outbreaks shared variants with earlier outbreaks or shipping environment samples, suggesting that the detected DNA generally reflected infectious particles rather than just free environmental DNA and indicating that CEV can go unnoticed for several months after importation. These findings highlight the utility of environmental samples for effective, non-invasive surveillance and improved biosecurity management in the koi trade.</p>","PeriodicalId":23658,"journal":{"name":"Veterinary Research","volume":"56 1","pages":"48"},"PeriodicalIF":3.7,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11881292/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143558124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our previous research identified the two-component system PhoPR within the genome of R. anatipestifer and demonstrated its association with the bacterium's pathogenicity. Through multi-omics analysis, we found that PhoP directly regulates the expression of several genes, including moxR, within the Bacteroides aerotolerance (Bat) operon.

To investigate the impact of MoxR on the expression of the bat operon and the pathogenicity of R. anatipestifer, we constructed ΔmoxR and other derivative strains. Our findings revealed that overexpression of MoxR inhibits the transcription of the bat operon. Conversely, deletion of moxR, along with exposure of R. anatipestifer to thermal or oxidative stress, results in increased transcription levels of the bat operon. By measuring the survival ability of each strain under stress, we discovered that MoxR is closely associated with the resistance of R. anatipestifer to thermal and oxidative stress by influencing the expression of the bat operon. Duckling infection experiments, along with adhesion and invasion assays, showed that deletion of moxR in R. anatipestifer led to decreased pathogenicity, and lower bacterial load in various tissues.

The mechanisms by which bovine enteroviruses evade the host immune response and promote their replication remain unclear. This study used the HY12 strain of enterovirus as a model to investigate its interaction with both bovine enterovirus and its host. Our findings indicate that bovine enterovirus promotes the replication of HY12 by disrupting the NF-κB pathway. Here, one strategy was to down-regulate the IΚBΚB expression to inhibit the activation of NF-κB. Another approach was to directly interact with p65 to reduce the dimerisation of p65/p50 and inhibit the phosphorylation and nuclear translocation of p65. Our study's results show that 2C's N-terminal 1-121 aa is essential for 2C-mediated inhibition of the NF-κB signalling pathway, and four amino acids (position 118-121 aa) are the interaction site of 2C with p65. This report is the first on BEV 2C protein promoting virus replication through new strategies, which provides novel insights into the understanding of enterovirus pathobiology and the development of drugs against BEV.</p>","PeriodicalId":23658,"journal":{"name":"Veterinary Research","volume":"56 1","pages":"42"},"PeriodicalIF":3.7,"publicationDate":"2025-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11831767/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143433797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
