A 58-years-old male with history of previous aortic prosthetic endocarditis caused by Enterococcus faecalis was admitted due to dyspnoea and fever. The two sets of blood cultures were positive for Neisseria bacilliformis. Transoesophageal echocardiography did not demonstrate endocarditis signs, but PET-CT scan showed active infection signs in the valvular aortic tube and possible infection in the aortic prosthetic valve. A six-week course of ampicillin was prescribed; gentamicin was added during the first two weeks. The patient continued a favourable clinical course. This is the 3rd described case of N. bacilliformis endocarditis and the first one in a prosthetic valve.
一名58岁男性，既往有粪肠球菌引起的主动脉人工瓣膜心内膜炎病史，因呼吸困难和发热入院。两组血培养均为杆状奈瑟菌阳性。经食管超声心动图未显示心内膜炎迹象，但PET-CT扫描显示主动脉瓣管有活动性感染迹象，人工主动脉瓣可能存在感染。给予六周疗程的氨苄西林；前两周加用庆大霉素。患者临床病程进展良好。这是第三例报道的杆状奈瑟菌心内膜炎病例，也是人工瓣膜的首例。
