Propionibacterium (Propionimicrobium) lymphophilum is a Gram-positive anaerobic rod involved in few human diseases. We report a rare case of bacteremia due to this microorganism in an elderly patient. A 95-year-old woman without a remarkable medical history presented with dyspnea, chest pain and fever for seven days. Blood cultures resulted in isolation of P. lymphophilum. Resistance only to metronidazole was found. Treatment with amoxicillin-clavulanic acid was established, and the patient was discharged and improvement of her general condition was documented.

丙酸杆菌（Propionimicrobium）淋巴球菌是一种革兰氏阳性厌氧菌，很少涉及人类疾病。我们报道了在老年患者中因这种微生物引起的菌血症的罕见情况。一名无明显病史的95岁妇女出现呼吸困难，胸痛和发烧7天。血液培养导致分离出P.lymphophilum。发现仅对甲硝唑具有抗性。建立了阿莫西林-克拉维酸治疗，该患者已出院，并记录了其总体状况的改善。
