Here, we report that BoAHV1 productive infection leads to increased steady-state protein expression of EEF1D in cell cultures. Immunofluorescence assays demonstrated that productive viral infection in MDBK cells induces the enhanced translocation of EEF1D into the nucleus, where it forms specific puncta and co-localizes with the puncta of viral protein ICP8, a marker of the viral replication compartment. Additionally, viral infection in MDBK cells re-localizes a portion of EEF1D in the cytoplasm, where it co-localizes with the virion-associated proteins, such as viral protein gD. While, co-localization of EEF1D with virion-associated proteins is primarily observed in the nuclei of virus-infected Neuro-2A cells. Moreover, siRNA-mediated knockdown of EEF1D expression significantly decreases BoAHV1 productive infection in MDBK cells. Thus, the association of EEF1D with multiple viral proteins, particularly ICP8, a component of the viral replication compartment, may represent a potential mechanism by which EEF1D regulates viral replication.</div></div>","PeriodicalId":23551,"journal":{"name":"Veterinary microbiology","volume":"307 ","pages":"Article 110613"},"PeriodicalIF":2.4,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144489387","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}

Diagnostic examinations of broiler carcasses revealed classical colibacillosis indicators such as polyserositis, cellulitis, and femoral head necrosis. Avian pathogenic <em>Escherichia coli</em> (APEC) isolates were mainly collected from the bone marrow of diseased birds for molecular typing by PCR. Typing was conducted for 375 and 217 APEC isolates from 64 and 91 flocks from the years 2015 and 2021, respectively. Typing consisted of determination of the <em>E. coli</em> phylogeny group, O-serogroup, and eight virulence-associated genes. Two predominant APEC types were detected in the 2015 outbreak and one in the 2021 outbreak. These predominant types were present in the majority of investigated flocks (47 out of 64 flocks (73 %) in 2015 and 75 out of 91 flocks (81 %) in 2021). Subsequent whole-genome sequencing (WGS) analysis of a subset of APEC isolates of these predominant types revealed them to be ST117 O78:H4 and ST117 O53:H4 in 2015 and ST23 O78:H4 in 2021. The isolates represented three distinct clonal lineages with small genetic differences. In addition, APEC isolates belonging to the same clonal lineages were detected in other Nordic countries at the same time. The affected flocks were epidemiologically linked by common ancestral parent and grandparent flocks. This study underscores that certain APEC strains with a high virulence potential can trigger severe colibacillosis outbreaks affecting multiple farms in several countries by vertical transmission from ancestral flocks to offspring. PCR typing emerged as a cost-effective and reliable method for promptly detecting the APEC clonal lineages responsible for colibacillosis outbreaks, and subsequent WGS analysis provided more detailed epidemiological and genetic information. The results of this study could also be used in assessing sampling methods and determining genetic differences between APEC isolates in the diagnosis of potential colibacillosis outbreaks.</div></div>","PeriodicalId":23551,"journal":{"name":"Veterinary microbiology","volume":"308 ","pages":"Article 110617"},"PeriodicalIF":2.4,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144580739","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}

Western blot analysis revealed that SBV caused autophagy induction at 48 h post infection. Several markers, such as PI3K, Akt, and Wnt/β-catenin, were downregulated at the same time point. Furthermore, downregulation in the expression of PI3K, p-mTOR and Beclin-1 showed differences between multiplicity of infection (MOI) 0.05 and 0.5, but not between MOI 0.5 and 1.5. Exceptions for this trend were Akt and LC3-II, which progressively decreased depending on time, and β-catenin, whose expression almost disappeared regardless of MOI. The use of several chemical inducers and inhibitors has demonstrated the efficacy of late autophagy inhibitors (bafilomycin and chloroquine) in significantly lowering SBV infection and also preventing the changes caused by viral replication. Early autophagy inhibitors and inducers showed no effect on cellular viability or viral titers. Silencing the expression of Akt and β-catenin revealed a slight increase in the expression of viral glycoprotein Gc. These findings revealed the relationship that SBV has in important cellular regulatory pathways, expanding the knowledge about the cellular interactions of this virus and suggesting a central role for late stages of autophagy in the replication of this bunyavirus.</div></div>","PeriodicalId":23551,"journal":{"name":"Veterinary microbiology","volume":"307 ","pages":"Article 110609"},"PeriodicalIF":2.4,"publicationDate":"2025-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144307290","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}
