Sepsis manifests as fever, hemorrhagic lesions and cell death. Organ dysfunction caused by sepsis, such as meningitis and encephalitis, can lead to organ damage. Sepsis is induced by various viral components, host cells and cellular mediators, such as cytokines and chemokines. Cytokines are secreted from stimulated macrophages, monocytes, dendritic cells and T lymphocytes.Further contributors to sepsis are the cleavage products after activation of the complement cascade with anaphylatoxin generation and peptides of the activated clotting cascade, thrombocytopenia and thrombocyte function alteration, intravasal clotting and/or endothelial leakage. The cells involved in viral sepsis are neutrophil granulocytes, monocytes and macrophages, dendritic cells and thrombocytes, and finally, endothelial cells and epithelial cells.Prolonged cytokine release leads to cell damage, immune cell dysfunction and exhaustion, and either impairs or hyperactivates immune cells. The course of viral sepsis may be enhanced by some patient conditions including age, underlying diseases such as diabetes, obesity; and immunodeficiency.

However, with the introduction of milk pasteurization and hygienic improvements in livestock farming and animal welfare, no cases of milk-linked human diphtheria outbreaks or bovine mastitis due to toxigenic corynebacterial have been reported in the recent decades. Here we report the first isolation of a toxigenic Corynebacterium ulcerans strain from the milk of a cow with acute mastitis within nearly 40 years and outside of UK or Finland.</p><p><strong>Methods: </strong>The isolated strain was analysed by state-of-the-art bacteriological methods including toxigenicity testing by a novel Lateral Flow Immunoassay and Elek test, molecular typing was done by whole genome sequencing and MLST/cgMLST analysis. Due to the rarity of our finding, an extensive historical review of milk-associated diphtheria outbreaks was performed.</p><p><strong>Results: </strong>The obtained sequence type ST-331 is also found in human isolates of cutaneous diphtheria. cgMLST analysis, however, found no close relationship to 43 human ST-331 isolates from our German strain collection or to two animal samples from a zoonic cluster of this ST.</p><p><strong>Conclusion: </strong>The risk of milk-associated diphtheria due to C. ulcerans, although today extremely rare, should be avoided by milk pasteurization and the respective hygienic standards.</p>","PeriodicalId":13600,"journal":{"name":"Infection","volume":" ","pages":"767-774"},"PeriodicalIF":5.4,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143457829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
