为探讨B群脑膜炎双球菌脑膜炎 (B群流脑 )的临床特点 ,对102例B群流脑与98例A群流脑在发病年龄、合并症、暴发型的发生率及死亡率方面进行对照分析。结果发现B群流脑发病年龄小 ,多见于1岁以下婴儿(51.0% ) ,合并症多 ;暴发型的发生率及死亡率 (31.4% ,11 .8 % )较A群 (24.4% ,6.1% )在统计学上差异虽无显著性 ,但临床资料显示有增高趋势。提示B群脑膜炎双球菌致病力可能较强 In order to explore the clinical features of meningitis group B meningitis (B group meningitis), 102 cases of group B meningitis and 98 cases of group A meningitis in the incidence of age, comorbidity, fulminant incidence and mortality Control analysis. The results showed that the incidence of meningitis in Group B was small and more common in infants under 1 year old (51.0%), with more complications; the incidence and mortality of fulminant episodes (31.4% and 11.8% %) Although statistically significant differences, but the clinical data showed an upward trend. Tip B group meningococcus may be stronger virulence
