Abstract

Anaerobiospirillum succiniciproducens is a spiral-shaped, gram-negative anaerobic bacterium. A. succiniciproducens is a rare cause of bacteremia in human, especially immunocompromised patients. This organism may be mistakenly identified when using an automated bacterial identification system, and may be mistaken for Campylobacter spp. when using Gram staining. We report a case of bacteremia caused by A. succiniciproducens, which was negative for catalase, oxidase, and urease and confirmed by 16S rRNA sequencing (analysis revealed a 99% similarity), in a 69-year-old patient who was undergoing chemotherapy for treatment of a malignancy. To the best of our knowledge, this is the first report of bacteremia caused by A. succiniciproducens in Korea. (Korean J Clin Microbiol 2012;15:74-77)

产琥珀酸厌氧菌血培养分离一例
琥珀酸产厌氧菌是一种螺旋形的革兰氏阴性厌氧菌。琥珀酸甲杆菌是人类罕见的菌血症,尤其是免疫功能低下的患者。当使用自动细菌鉴定系统时,这种生物可能被错误地识别出来,当使用革兰氏染色时,可能被误认为弯曲杆菌。我们报告一例69岁的恶性肿瘤化疗患者,由琥珀酸甲杆菌引起的菌血症,其过氧化氢酶、氧化酶和脲酶均阴性,并经16S rRNA测序证实(分析显示相似性为99%)。据我们所知,这是韩国首次报道由琥珀酸芽孢杆菌引起的菌血症。(韩国临床微生物杂志2012;15:74-77)
