Isolation of Abiotrophia adiacens from a Brain Abscess Which Developed in a Patient after Neurosurgery

We report the case of a patient who developed a large brain abscess after neurosurgery. Cerebrospinal fluid from the abscess drainage yielded Abiotrophia adiacens-specific PCR products and microorganisms that were identified by conventional microbiological methods and by 16S ribosomal DNA analysis as Abiotrophia adiacens, which was formerly classified as a member of nutritionally variant streptococci.

本研究报告1例神经外科术后继发大面积脑脓肿的患者病例。对该患者脓肿引流获取的脑脊液标本进行检测，检出毗邻贫养菌（Abiotrophia adiacens）特异性聚合酶链式反应（PCR）扩增产物；经传统微生物学方法及16S核糖体DNA分析（16S ribosomal DNA analysis）鉴定，确认所分离得到的微生物为毗邻贫养菌，该菌曾被归类为营养变异链球菌群的成员。
