Porphyromonas species are Gram-negative anaerobic bacilli mainly involved in human periodontal diseases. We report an uncommon case of bacteremia due to P. asaccharolytica in a patient with necrotizing fasciitis. A 52-year-old woman with a history of diabetes mellitus was admitted for an extensive necrotizing lesion on the left lower limb. After she developed septic shock, two sets of blood cultures were taken. Anaerobic bottles yielded a pure culture of a microorganism initially identified as P. uenonis by MALDI-TOF MS but with a low log score, and a gene sequencing technique was therefore applied, identifying the isolate as P. asaccharolytica. Only resistance to penicillin and clindamycin was documented. Treatment with meropenem was administered, and the patient was discharged following her recovery.

坏死性筋膜炎患者由解糖卟啉单胞菌引起菌血症的罕见原因

卟啉单胞菌属革兰氏阴性厌氧菌,主要与人类牙周病有关。我们报告了一例坏死性筋膜炎患者由解糖假单胞菌引起的罕见菌血症病例。一名有糖尿病病史的 52 岁女性因左下肢广泛坏死性病变入院。在她出现感染性休克后,进行了两组血培养。厌氧瓶产生了一种微生物的纯培养物,最初通过 MALDI-TOF MS 鉴定为P. uenonis,但对数得分低,因此应用了基因测序技术,将分离物鉴定为P. asaccharolytica。仅记录了对青霉素和克林霉素的耐药性。给予美罗培南治疗,患者康复后出院。
