Streptococcus milleri (S. milleri) is found in healthy individuals in the mouth, nasopharynx, throat, vagina and in feces, and has been reported to be isolated from several infectious diseases in man, particularly from abscess in various parts of the body. We report two cases of severe infections due to S. milleri isolated from subdural abscess and pleural empyema. [Case 1] 13 year old boy who had been healthy until he was noticed to have meningeal signs and was diagnosed as left subdural abscess with siagonantritis by cranial CT scans. S. milleri was isolated from subdural abscess and maxillary sinus. [Case 2] 10 year old boy who had encephalitis and severe mental retardation after measles at 6 months of age. He had a fever, dyspnea and chest X-ray abnormalities and was diagnosed as right pleural empyema. Three strains of organism, S milleri, Bacteroides spp. and Fusobacterium nucleatum were isolated from the pleural effusion.
米勒链球菌（S. milleri）在健康个体的口腔、鼻咽部、咽喉、阴道及粪便中均可发现，据报道，该菌可从人类的多种传染病中分离得到，尤其是从身体各部位的脓肿中分离得到。我们报告了两例因米勒链球菌引起的严重感染病例，分别从硬膜下脓肿和胸腔积脓中分离出该菌。[病例1]一名13岁男孩，此前一直健康，后出现脑膜刺激征，经头颅CT扫描诊断为左侧硬膜下脓肿伴上颌窦炎。从硬膜下脓肿和上颌窦中分离出米勒链球菌。[病例2]一名10岁男孩，6个月大时患麻疹后出现脑炎及严重智力发育迟缓。他发热、呼吸困难，胸部X线检查有异常，诊断为右侧胸腔积脓。从胸腔积液中分离出三种微生物，即米勒链球菌、拟杆菌属和具核梭杆菌。
