A rare case of prosthetic valve endocarditis from Acinetobacter spp occurring 9 months postoperatively is described. The patient initially received empirical therapy against pathogens commonly associated with prosthetic valve endocarditis, but his condition did not improve. Identification of bacteremia due to Acinetobacter spp was not attributed to any of the classic nosocomial factors such as presence of a catheter or a recent invasive procedure. The patient did well with an intravenous regimen of meropenem and tobramycin instituted according to susceptibility testing. Physicians should be aware of this rare association of a nosocomial pathogen such as Acinetobacter spp with prosthetic valve endocarditis occurring long after the initial cardiothoracic procedure.
本文描述了1例术后9个月发生的由不动杆菌属引起的人工瓣膜心内膜炎罕见病例。患者最初接受了针对人工瓣膜心内膜炎常见相关病原体的经验性治疗，但病情并未改善。不动杆菌属所致菌血症的鉴定并非归因于任何典型的医院感染因素，如存在导管或近期的侵入性操作。根据药敏试验，患者接受美罗培南和妥布霉素静脉治疗方案后病情好转。医生应意识到这种医院病原体如不动杆菌属与初次心胸手术后很长时间发生的人工瓣膜心内膜炎之间的罕见关联。
