Abstract

Corynebacterium striatum is a gram-positive curved bacilli included in “diphtheroids”. It is now being reported as a significant multidrug resistant nosocomial pathogen in immunocompromised patients. We describe a case of Catheter-related bloodstream infection caused by Corynebacterium striatum in an 86-year-old patient suffering from Acute Myeloid leukaemia. Rapid MALDI-TOF MS based identification of paired blood culture isolates confirmed true CRBSI. Prompt catheter removal and vancomycin therapy led to recovery. This case underscores the significance of MDR Corynebacterium striatum in oncology settings. It further emphasizes the need to identify and test for antimicrobial susceptibility of diphtheroids.

打破污染的神话：在中性粒细胞减少患者中使用MALDI-TOF早期识别耐多药纹状棒状杆菌。

纹状棒状杆菌是一种革兰氏阳性弯曲杆菌，包括在“类白喉”中。目前有报道称，在免疫功能低下患者中，它是一种重要的多药耐药医院病原体。我们描述了一个病例导管相关血流感染引起的纹状棒状杆菌在一个86岁的病人患有急性髓性白血病。基于MALDI-TOF MS的配对血培养分离物的快速鉴定证实了真正的CRBSI。及时拔管和万古霉素治疗使患者恢复。该病例强调了耐多药纹状棒状杆菌在肿瘤学领域的重要性。它进一步强调需要确定和检测类白喉的抗菌素敏感性。
