严格地说,任何微生物侵入中枢神经系统均可引起感染,而对于其他脏器,就不那么容易了。要确定中枢神经系统的机会感染是困难的,而且病例少,除主要致病菌外,其他细菌引起的疾病只是病案报道,难以掌握整个情况。本文对细菌性中枢神经感染症,特别以脑脊髓膜炎(简称脑膜炎)为重点,从宿主与微生物两方面,予以概述。一、中枢神经感染症的特殊性化脓性脑膜炎的主要致病菌是流感杆菌、肺炎球菌、脑膜炎双球菌。据美国统计,年发 Strictly speaking, any microbes invade the central nervous system can cause infection, while for other organs, it is not so easy. It is difficult to determine the opportunistic infections of the central nervous system and there are few cases. Apart from the major pathogens, the diseases caused by other bacteria are just case reports and it is difficult to grasp the whole situation. This article focuses on bacterial CNS infections, especially meningococcal meningitis (meningitis), which are summarized in both host and microbiology. First, the special nature of CNS infection The main pathogens of purulent meningitis is influenza bacilli, pneumococcus, meningococcus. According to US statistics, the annual hair
