Fusobacterium necrophorum, a gram-negative anaerobe, causes pharyngotonsillitis primarily in adolescents and young adults (approximately 15-30 years old). The same age group has the highest incidence of peritonsillar abscess and the Lemierre syndrome. The same organism, F. necrophorum, is the most common cause of peritonsillar abscess in this age group and causes at least 80% of Lemierre syndrome cases. We outline the case for empiric antibiotic treatment of some patient in this age group who have a significant probability that F. necrophorum is the cause of their pharyngotonsillitis.

坏死梭杆菌咽扁桃体炎

坏死梭杆菌是一种革兰氏阴性厌氧菌，主要在青少年和年轻人（约 15-30 岁）中引起咽扁桃体炎。同一年龄组的扁桃体周围脓肿和Lemierre综合征的发病率最高。同一种微生物，即坏死性镰刀菌，是该年龄组扁桃体周围脓肿的最常见原因，并且导致至少 80% 的 Lemierre 综合征病例。我们概述了对这个年龄组中的一些患者进行经验性抗生素治疗的案例，这些患者极有可能是坏死杆菌是其咽扁桃体炎的原因。
