由于厌氧菌分离技术的提高及临床和基础医学密切配合的结果,近十余年来厌氧菌族已证实是败血症的常见病因。本文仅就厌氧菌败血症发病情况、诊断和治疗等情况作一介绍。一、发病情况:近年来厌氧菌败血症已占一般败血症的8～11%,较以往明显增高。致病菌中以脆弱类杆菌最常见(50～90%),可能与脆弱类杆菌对目前广泛使用的某些抗菌素耐药有关。新生儿及21～30岁的青年中厌氧菌败血症的发生率较高。 Due to the improvement of anaerobic bacteria separation technology and the close cooperation between clinical and basic medicine, the anaerobic bacteria family has been proved to be a common cause of sepsis in the recent ten years. This article only on the incidence of anaerobic sepsis, diagnosis and treatment of such an introduction. First, the incidence: In recent years, anaerobic sepsis has accounted for 8 to 11% of the general sepsis, significantly higher than in the past. Bacteroides fragilis in the most common (50 ~ 90%), Bacteroides fragilis may be related to the widespread use of certain antibiotic resistance. The incidence of anaerobic sepsis is higher among newborns and young people aged 21 to 30 years.
