Prevotella species are Gram-negative anaerobic bacilli mainly involved in oral cavity infections. We report a rare case of bacteremia due to P. oris of probable hepatic origin. A 70-year-old man with a history of diabetes mellitus was admitted for general malaise, fever and dyspnea. The patient was admitted to the ICU due to septic shock. Two sets of blood cultures yielded a pure culture of an anaerobic microorganism identified as P. oris by MALDI-TOF MS. The same microorganism was isolated from a hepatic abscess drainage. Only resistance to penicillin was documented. Treatment with piperacillin-tazobactam and levofloxacin was administered, and the patient was discharged following his recovery.
普雷沃氏菌属是一种主要参与口腔感染的革兰氏阴性厌氧杆菌。我们报告了一例由可能源自肝脏的口腔普雷沃氏菌引起的菌血症的罕见病例。一名 70 岁男性，患有糖尿病病史，因全身不适、发热和呼吸困难入院。患者因感染性休克而被收入 ICU。两套血培养均获得纯培养，经 MALDI-TOF MS 鉴定为口腔普雷沃氏菌。同一微生物从肝脓肿引流中分离出来。仅记录到对青霉素的耐药性。给予哌拉西林他唑巴坦和左氧氟沙星治疗，患者恢复后出院。
