We describe an episode of Leptotrichia trevisanii bacteraemia in a neutropenic hemato-oncology patient receiving chemotherapy for Refractory Anemia with Excess Blasts-2 (RAEB-2). Although Leptotrichia spp. colonize the oral cavity and genitourinary tract, serious episodes of bacteraemia might occur in immunocompromised patients, particularly in those with severe neutropenia. Therefore, microbiologists should consider the possibility of Leptotrichia spp. septicemia in patients with blood cultures positive for gram negative bacilli, when routine microbiology tests fail to reveal a correct identification of the organism.
我们描述了一例嗜唾二氧化碳噬纤维菌血症，发生于一名接受化疗治疗难治性贫血伴原始细胞过多-2（RAEB-2）的中性粒细胞减少症血液肿瘤患者。虽然嗜唾二氧化碳噬纤维菌定植于口腔和泌尿生殖道，但严重的菌血症可能发生于免疫功能低下的患者，尤其是严重中性粒细胞减少症患者。因此，当常规微生物学检测未能正确鉴定病原体时，微生物学家应考虑血培养革兰氏阴性杆菌阳性的患者发生嗜唾二氧化碳噬纤维菌败血症的可能性。
