Abstract：
Background: Raoultella planticola is an uncommon gram-negative organism found in the environment. Patients and Methods: The patient, an 81-year-old female who had undergone total cystectomy and bilateral ureteral stoma surgery, presented to the hospital with a fever. It was determined that Raoultella planticola was responsible for the bacteremia. Results: Rapid identification of bacteria using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) in blood culture samples and appropriate antibacterial treatment was begun and the patient was discharged three days later. Conclusions: This case emphasizes the presence of a rare pathogen as the cause of bacteremia and underscores the importance of utilizing rapid methods for bacterial identification to establish an accurate diagnosis.
摘要：
背景：扁平Raoultella是在环境中发现的一种罕见的革兰氏阴性生物。患者和方法：患者，一名81岁的女性，曾接受全膀胱切除术和双侧输尿管造口手术，发烧被送到医院。确定拉氏拉氏菌是菌血症的原因。结果：采用基质辅助激光解吸/电离飞行时间质谱（MALDI-TOFMS）快速鉴定血培养样品中的细菌，并开始适当的抗菌治疗，三天后患者出院。结论：该病例强调了罕见病原体的存在是菌血症的原因，并强调了利用快速细菌鉴定方法建立准确诊断的重要性。
