Pseudoclavibacter spp. are Gram-positive, aerobic, catalase-positive, coryneform bacteria belonging to the family of Microbacteriaceae. Identification of these species with conventional biochemical assays is difficult. This case report of a Pseudoclavibacter bifida bacteremia occurring in an immunocompromised host diagnosed with an acute exacerbation of chronic obstructive pulmonary disease, with a lethal outcome, confirms that this organism may be a human pathogen.
假棒杆菌属是微杆菌科的革兰氏阳性、需氧、过氧化氢酶阳性、棒状细菌。这些种的常规生化鉴定比较困难。本报告一例免疫功能低下宿主发生的合并有慢性阻塞性肺病急性加重的双歧杆菌假棒杆菌菌血症,导致患者死亡,证实该菌可能是人类病原体。
