Clonal relationship and genetic diversity were assessed by multi-locus sequence typing (MLST) and pulsed-field gel electrophoresis (PFGE). Overall, 3.1% of isolates exhibited resistance to ciprofloxacin. Commonly identified mutations in QRDRs were S83F, D87N, and D87G in gyrA; T57S and S80I in parC; and L416F in parE. Furthermore, mutations differed by serotypes. In S. Albany, S83F mutation in gyrA and T57S in parC were prevalent, while in S. Kentucky, S83F and D87N in gyrA, T57S and S80I in parC; and in S. Indiana, S83F and D87G in gyrA, T57S and S80R in parC, and L416F in parE were common. Amongst PMQRs, qnrS was mainly observed in S. Albany, aac(6')-Ib-cr in S. Indiana, and qnrB1 in S. Albany. Among STs, ST198 S. Kentucky was predominant, followed by ST292 S. Albany and ST17 S. Indiana. Of 26 pulsotypes, KX1KA1 was mainly identified in S. Kentucky, AX1AA1 in S. Albany, and IX1IA1 in S.

The secretory immunoglobulin A levels in ileal contents were significantly higher compared to control piglets (p < 0.01). Key intestinal health parameters, including villus height, villus height-to-crypt depth ratio, and goblet cell numbers, showed linear and quadratic increases in both the jejunum and ileum (p < 0.05), while crypt depth decreased significantly (p < 0.01). Additionally, the expression of IL-10, ZO-1, occludin, and mucin2 was upregulated linearly and quadratically in IRP-fed piglets (p < 0.05). In cultured IPEC-J2 cells, ZO-1 and occludin expression levels significantly increased upon exposure to 400 μg/mL IRP (p < 0.01).

Phylogenetic network and recombination analyses were employed to investigate IBV evolutionary relationships and transmission pathways. The phylogenetic network revealed distinct clusters reflecting relationships between IBV strains. Importantly, these network patterns, combined with recombination event analysis, suggest an unrecognized role for migratory birds in IBV dissemination, highlighting potential transmission pathways beyond established poultry trade routes. These findings contribute to advancing our understanding of IBV evolution and support the development of targeted strategies for controlling viral outbreaks in poultry populations. While statistical limitations may affect threshold estimation for smaller networks, our MSClustering method significantly accelerates processing speeds-approximately 100,000 times faster than PhyML when analyzing the dataset-enabling comprehensive-scale phylogenetic analysis of viruses.","PeriodicalId":51207,"journal":{"name":"Veterinary Quarterly","volume":"45 1","pages":"1-14"},"PeriodicalIF":7.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11834806/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143415504","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}

Mastitis is defined as inflammation of the udder, and it is typically caused by bacterial infection. The effect of the MDEC secretome on macrophages, a first line of defense against bacterial infections in the udder, is unknown and could impact the utility of the secretome as a therapy for mastitis. To address this, we isolated bovine monocytes from peripheral blood and maintained them as an unpolarized (M0) population or polarized them into M1 or M2 phenotypes. Macrophages cultured with the secretome of bovine MDECs were assessed for their ability to phagocytose labeled bacterial particles and accumulate reactive oxygen species (ROS). We used single-cell RNA sequencing (scRNA-seq) and fluorescence-activated cell sorting (FACS) to isolate a subpopulation of MDECs that exert enhanced effects on macrophages. We found that the secretome of MDECs that do not express cluster of differentiation (CD) 73, a cell surface enzyme used as a marker for mesenchymal stromal cells, most strongly increased macrophage phagocytosis and ROS accumulation. These findings will help optimize the generation of the bovine MDEC secretome as a suitable treatment option for mastitis.","PeriodicalId":51207,"journal":{"name":"Veterinary Quarterly","volume":"45 1","pages":"1-14"},"PeriodicalIF":7.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11809179/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143374957","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 resistance phenotype for 19 antimicrobials was determined using broth microdilution in 75 Pasteurella multocida isolates from healthy and BRD-affected cattle from five feedlots. The genomes of 32 isolates were sequenced to identify ARG) and mobile genetic elements (MGEs) and assess their genetic diversity. MDR isolates (with phenotypic resistance to aminoglycosides, macrolides, fluoroquinolones and/or tetracyclines) were primarily found among BRD-affected compared to healthy animals. Non-susceptible isolates, belonging to ST79 and ST13, harbored point mutations and four to nine ARGs, including rarely reported mechanisms in Europe (mph(E), msr(E) and aadA31 ARGs and newly described mutations in the gyrA/parC genes). All ARGs were linked to the presence of MGEs including two ICEs, Tn7407 and the novel Tn7809, a prophage and a putative composite transposon. Clonally related isolates were found in different batches from the same feedlot, suggesting maintenance of MDR strains. Our findings demonstrate the diverse genetic basis of AMR in P. multocida from BRD-affected cattle in Spain, emphasizing the role of MGEs in the ARG dissemination.","PeriodicalId":51207,"journal":{"name":"Veterinary Quarterly","volume":"45 1","pages":"1-15"},"PeriodicalIF":7.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11892046/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143587733","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}
