To determine differences in clinical characteristics of patients with bacteremia caused by , , and other species of , we retrospectively reviewed medical records of patients in Japan who had bacteremia during January 2014–May 2020. Of the 115 records evaluated, 60 (52%) were cases of true bacteremia and 55 (48%) were cases of contamination. Proportions of true bacteremia cases caused by (70%) and by (71%) were significantly higher than those caused by other species of (9%). These 2 organisms were commonly detected in blood cultures of patients with hematologic malignancies and neutropenia. The mortality rates at 90 days were 34% (), 30% (), and 0 (other species). Given the high mortality rates, assessing true bacteremia when or is detected in blood cultures, especially in patients with hematologic malignancy, is warranted.
为了确定由 、 和其他 种属引起的菌血症患者的临床特征差异，我们回顾性分析了 2014 年 1 月至 2020 年 5 月期间日本菌血症患者的病历。在评估的 115 份记录中，60 份（52%）为真性菌血症病例，55 份（48%）为污染病例。由 （70%）和 （71%）引起的真性菌血症病例比例明显高于其他 种属（9%）。这两种生物体通常在血液培养物中检测到血液恶性肿瘤和中性粒细胞减少症患者。90 天的死亡率分别为 34%（）、30%（）和 0（其他种属）。鉴于高死亡率，当血液培养物中检测到 或 时，尤其是在血液恶性肿瘤患者中，评估真性菌血症是有必要的。
