本文报导1975年建立的特殊细菌实验室在提高厌氧菌培养的阳性率和改善厌氧菌颅内化脓感染的疗效上的成就.耳源性颅内化脓感染大多由Gram(+)和Gram(-)厌氧菌所引起.但通常细菌培养结果大多阴性,难以确诊,疗效差.本组1968～1979年收治脑脓肿90例,总死亡率为11%,显然低于一般文献报道者.作者认为,疗效的改进并非由于手术技术上有所创新 This article reports the achievements of special bacteria laboratories established in 1975 in improving the positive rate of anaerobic culture and improving the efficacy of anaerobic intracranial purulent infection.Currently, the majority of ear-derived intracranial suppurative infections are caused by Gram (+) and Gram (+ -) anaerobic bacteria caused, but usually the results of bacterial culture were mostly negative, difficult to diagnose, poor efficacy in this group of 1968 to 1979 admitted 90 cases of brain abscess, the overall mortality rate was 11%, apparently lower than those reported in the literature. That the improvement of efficacy is not due to surgical innovations
