The causative organism is not identified in some cases of infected aneurysms, a life-threatening condition. A 68-year-old man presented with chest/back pain and a 1-year history of intermittent fever and fatigue. Computed tomography revealed a thoracic aortic aneurysm. After several negative blood cultures, he was eventually diagnosed with an infected aneurysm caused by via gene analysis of an aortic tissue specimen. As is a low-virulence bacterium, infection with this pathogen should be suspected in cases of aortic aneurysms with unidentified causative organism and a long history of subjective symptoms. Detailed examinations, including polymerase chain reaction, should be conducted in such cases.
在一些感染性动脉瘤病例中，致病微生物未被识别出来，这是一种危及生命的疾病。一名68岁男性出现胸痛/背痛，并有1年间歇性发热和疲劳病史。计算机断层扫描显示为胸主动脉瘤。经过多次血培养结果均为阴性后，最终通过对主动脉组织标本进行基因分析，诊断他患有由[未提及具体细菌名称]引起的感染性动脉瘤。由于[未提及具体细菌名称]是一种低毒力细菌，对于致病微生物未明确且有长期主观症状病史的主动脉瘤病例，应怀疑感染了这种病原体。在此类病例中应进行包括聚合酶链反应在内的详细检查。
