少见性脑膜炎系由不同的细菌、霉菌及寄生虫所引起的一些脑膜炎,而接种性脑膜炎则大都为神经外科手术后所致的医源性脑膜炎.一、少见性病源菌脑膜炎:每易在特殊素质基础上发病,诸如糖尿病、免疫抑制状态(癌肿、血液病)、全身性严重感染、各种内脏病、手术后等.临床上无典型表现,惟赖CSP细菌培养及特殊检查方能确定,故诊断困难.一般病程长,预后大多严重.致病菌可分为四大类:Ⅰ类:治疗可奏效者:(一)、肠细菌属:呈典型化脓性脑膜炎,病源菌易鉴定.偶为罕见的Citrobacter Freundil或Enterobacter Hafnia,则治疗困难.(二)、假单胞菌属:发病率已渐增多,绿脓杆菌感染每多见于高龄和幼
Meningitis is a rare cause of meningitis caused by different bacteria, molds and parasites, while inoculation meningitis is mostly iatrogenic meningitis caused by neurosurgery. : Each easy on the basis of the special quality of onset, such as diabetes, immunosuppressive state (cancer, hematological disease), systemic infection, various visceral disease, after surgery, etc. Clinical no typical performance, but depends on CSP bacterial culture and Special inspection can be identified, it is difficult to diagnose. General duration of the disease, the prognosis is mostly serious. Pathogenic bacteria can be divided into four categories: Class I: the treatment can be effective: (A), enteric bacteria: a typical purulent meningitis , The pathogen easily identified, even for the rare Citrobacter Freundil or Enterobacter Hafnia, the treatment is difficult. (B), Pseudomonas: the incidence has been increasing, Pseudomonas aeruginosa infections are more common in older and younger
