Fusobacteria is anaerobic gram-negative rods, which frequently colonize the oral cavity and can rarely cause deadly diseases in humans. The two most commonly found in this group of bacteria are fusobacterium necrophorum and fusobacterium nucleatum. Only a handful of cases of endocarditis due to fusobacterium have been reported. We describe an 86-year-old male who had a recent tooth extraction presenting to the emergency department with weakness lightheadedness, and pain in his right elbow. He had a low-grade fever of 100.8°. The patient was discharged home but came back less than 24 hours with a fever of 102° and chills and again after the second discharge with sepsis of unknown origin. A week after initial blood cultures were drawn, fusobacterium nucleatum grew in one of two sets and his transesophageal echocardiogram revealed vegetation on his mitral valve. The patient was then successfully treated with a six weeks course of ampicillin-sulbactam. This case is followed by a review of the literature.
梭杆菌属是革兰氏阴性厌氧菌，常定植于口腔，极少在人类中引发致命疾病。该组细菌中最常见的两种是坏死梭杆菌和具核梭杆菌。仅有少数几例由梭杆菌引起的心内膜炎病例报告。我们描述了一名86岁男性，他近期拔牙后因虚弱、头晕和右肘疼痛前往急诊科就诊。他有低热，体温为100.8°。患者出院回家，但不到24小时后因发热102°和寒战再次就诊，第二次出院后又因不明原因的败血症再次就诊。首次采集血培养一周后，具核梭杆菌在两组血培养中的一组中生长，经食管超声心动图显示其二尖瓣上有赘生物。该患者随后成功接受了为期六周的氨苄西林-舒巴坦治疗。本文随后对相关文献进行了综述。
