Microorganisms of the genus Methylobacterium are facultative methylotrophic, gram-negative rods that are ubiquitous in nature and rarely cause human disease, mostly in subjects with preexisting causes of immune depression. Methylobacterium fujisawaense, first proposed as a new species in 1988, has never been reported as a bacterial agent of human infections so far. Here we describe a case of M. fujisawaense infection in a relapsed acute leukaemia undergoing unrelated allogeneic hematopoietic stem cell transplantation. Molecular identification of an M. fujisawaense strain was obtained from multiple mycobacterial blood cultures.
甲基杆菌属的微生物是兼性甲基营养型革兰氏阴性杆菌,在自然界中普遍存在,很少引起人类疾病,主要发生在已有免疫抑制病因的患者中。藤泽甲基杆菌于1988年首次被提议作为一个新物种,迄今为止从未有作为人类感染病原体的报道。在此,我们描述了1例正在接受非亲缘异基因造血干细胞移植的复发性急性白血病患者发生藤泽甲基杆菌感染的病例。从多次分枝杆菌血培养中获得了1株藤泽甲基杆菌的分子鉴定结果。
