| Abstract | We here report on a case of Leptotrichia trevisanii bacteremia in a patient with hematologic malignancy. A 64-year-old woman with multiple myeloma was admitted to our hospital for transplantation therapy. On the seventh day after autologous peripheral blood stem cell transplantation, she developed a fever and a blood culture test was performed. Bacterial growth in 2 independent blood culture sets was observed 4-5 days after the culture, but the Gram stain results for the culture media were unclear. The media from the blood culture-positive samples were immediately cultured, and bacterial growth was observed after 48 h in an anaerobic condition. Although the isolated bacterium was not identified using commercial biochemical test kits, 16S rRNA sequencing analyses finally revealed it as L. trevisanii. Previous studies have reported on blood stream infections caused by L. trevisanii in patients with hematologic malignancies; hence, bacterial laboratory findings and patient medical history are very important to ensure the accurate and timely diagnosis of L. trevisanii bacteremia in these patients. |
