摘要

背景和临床意义：bivia普氏菌是一种革兰氏阴性厌氧菌，通常与盆腔和生殖道感染有关。它与乳腺脓肿分离，特别是在非产褥期妇女中，是极为罕见的。病例介绍：我们报告一个独特的情况下，一个40岁的非哺乳期妇女提出复发性右乳房脓肿。患者在三年内（2022-2025）经历了三次发作；使用MALDI-TOF ms鉴定，只有第4次被微生物学证实是由双胞杆菌引起的，抗菌药物敏感性试验显示对氨苄西林耐药，对阿莫西林/克拉维酸和其他药物敏感。结论：该病例强调了厌氧培养和先进的识别技术在复发性乳房感染中的关键作用。虽然微生物学证实仅在最近一次发作中获得，但复发的临床图片提示难以培养的微生物病因学。

Anaerobic breast abscess caused by Prevotella bivia in non-lactating woman: A case report with diagnostic and clinical implications

Background and Clinical Significance

Prevotella bivia is an anaerobic Gram-negative bacillus commonly associated with pelvic and genital tract infections. Its isolation from breast abscesses, particularly in nonpuerperal women, is extremely uncommon.

Case presentation

We report a unique case of a 40-year-old non- lactating woman presenting with a recurrent right breast abscess. The pa- tient experienced three episodes over three years (2022–2025); only the fourth episode was microbiologically confirmed as being caused by P. bivia, identi- fied using MALDI-TOF MS. Antimicrobial susceptibility testing revealed resistance to ampicillin and susceptibility to amoxicillin/clavulanic acid and other agents.

Conclusion

The case underlines the critical role of anaerobic cultures and advanced identification techniques in recurrent breast infections. Although microbiological confirmation was achieved only in the latest episode, the recurrent clinical picture suggests a difficult-to-culture microbial aetiology.
