Bacteremia due to Fusobacterium spp. is unusual (<10% of cases of anaerobic bacteremia), and the isolation of Fusobacterium varium is especially uncommon. The most probable sources of Fusobacterium bacteremia are the respiratory, the gastrointestinal, and the genitourinary tracts. A.-M. Bourgault et al. (Clin. Infect. Dis. 25[Suppl. 2]:181-183) described 40 patients with Fusobacterium bacteremia; only 3 had Fusobacterium varium, and no one had decubitus scars as the portal of entry. In another published series (S. Henry, A. De Maria, and W. R. McCabe, Am. J. Med. 75:225-231, 1983) of 26 cases, two patients had concomitant pulmonary lesions and decubitus ulcers but there was no identification to the species level mentioned. We report a case of Fusobacterium varium bacteremia and infected sacral decubitus ulcer in an elderly patient.
具核梭杆菌引起的菌血症并不常见(占厌氧菌血症病例的比例不到10%),而多变梭杆菌的分离尤为罕见。具核梭杆菌菌血症最可能的来源是呼吸道、胃肠道和泌尿生殖道。A.-M. 布尔高特等人(《临床传染病》25[增刊2]:181 - 183)描述了40例具核梭杆菌菌血症患者;只有3例感染的是多变梭杆菌,且无人以褥疮瘢痕作为感染入口。在另一个已发表的系列研究(S. 亨利、A. 德玛丽亚和W. R. 麦凯布,《美国医学杂志》75:225 - 231,1983)中,26例病例里有两名患者同时患有肺部病变和褥疮溃疡,但未提及具体的菌种鉴定情况。我们报告一例老年患者发生多变梭杆菌菌血症并伴有骶部褥疮溃疡感染的病例。
