We report an uncommon case of bacteremia due to Lancefieldella parvula isolated in pure culture. We present a 72 year-old-man affected with cancer admitted with abdominal pain due to a parietal rupture of the urinary bladder. After surgical treatment, the patient developed fever and two sets of blood cultures yielded a pure culture of an anaerobic microorganism identified as L. parvula (formerly Atopobium parvulum) by MALDI-TOF MS, and confirmed by 16S rRNA gene sequencing. The isolate was susceptible to all antibiotics and the outcome was finally successful. Bacteremia due to L. parvula is an uncommon disease and, in that case, MALDI-TOF MS was an useful tool for the initial identification.
我们报告了一例由单纯培养分离出的小颗粒拉恩菲尔德菌引起的菌血症。我们介绍了一位 72 岁男性患者，患有癌症，因膀胱壁破裂导致腹痛入院。在接受手术治疗后，患者出现发热，两套血培养均培养出一种厌氧微生物，经 MALDI-TOF MS 鉴定为小颗粒拉恩菲尔德菌（以前称为细小阿托波菌），并通过 16S rRNA 基因测序得到确认。该分离株对所有抗生素均敏感，最终结果成功。小颗粒拉恩菲尔德菌引起的菌血症是一种罕见疾病，在这种情况下，MALDI-TOF MS 是一种有用的初始鉴定工具。
