Given the history of administrating living <em>C. butyricum</em> products before admission, probiotics-associated suppurative meningitis was considered a high possibility, leading to the confirmation of anti-infection treatment including vancomycin and meropenem.</div></div><div><h3>Results</h3><div>Following this therapy, the infant's CSF profiles demonstrated improvement. Additionally, further phylogenetic analysis confirmed the high homologous of <em>C. butyricum</em> from CSF with probiotics.</div></div><div><h3>Conclusions</h3><div>This is the first report of <em>C. butyricum</em> infection in neonates, highlighting the importance for prudence in administrating probiotics for neonates, particularly in high-risk groups such as preterm infants, those with central venous catheters and intestinal diseases.</div></div>","PeriodicalId":14006,"journal":{"name":"International Journal of Infectious Diseases","volume":"155 ","pages":"Article 107900"},"PeriodicalIF":4.8,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143788334","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}
