Actinobaculum species are anaerobic Gram-positive rods that have previously been associated with urinary tract infection (UTI) in the elderly. We report 12 patients with Actinobaculum bacteremia. Only 40% of blood cultures were clinically considered significant by the treating physicians, but most patients were treated for UTI, suggesting a possible urinary source of bacteremia. Clinicians should be aware of the pathogenic potential of Actinobaculum spp.
放线杆菌属是一种厌氧革兰氏阳性杆菌,以前与老年人的尿路感染(UTI)有关。我们报告了 12 例放线杆菌菌血症患者。只有 40%的血培养被治疗医生认为具有临床意义,但大多数患者接受了 UTI 的治疗,这表明菌血症可能有尿路来源。临床医生应该意识到放线杆菌属的致病潜力。
