摘要
目的对2005年北京地区流行性脑脊髓膜炎(流脑)进行病原学监测。方法对临床流脑病例的血液、脑脊液标本进行特异性核酸片段检测,对鉴定阳性的菌株进行脉冲场凝胶电泳 (PFGE)和多位点序列(MIST)分析。结果在7份血液和5份脑脊液标本中检测到脑膜炎奈瑟菌的核酸片段。共分离到105株脑膜炎奈瑟菌。A群和C群菌株的群内菌株PFGE图谱无差异条带。 MLST分析结果表明北京地区A群脑膜炎奈瑟菌的序列类型主要是ST7,而C群主要是ST4821。结论北京地区目前流脑病例主要由序列类型为ST7的A群和ST4821的C群脑膜炎奈瑟菌引起。
Objective To study the pathogens of meningoeoecal meningitis （MM） in Beijing,2005. Methods Blood and cerebrospinal fluid specimens from MM patients were detected by polymerase chain reaction. Bacterial strains were analyzed by pulsed-field gel electrophoresis and multilocus sequence typing. Results 7 of the blood and 5 of cerebrospinal fluid specimens showed positive results. 103 of the Neisseria meningitides strains were isolated from the specimens of patients, close contacts and heahby carriers. Serogroup A and C Nelsseria meningitides strains shared the same patterns of pulsed-fieldgel electrophoresis, respectively. The sequence type of serogroup A Neisseria meningitides belonged to ST7 while the sequence type of serogroup C Neisseria meningitides belonged to ST4821. Conclusion Patients suffered from meningococcal meningitis were caused by serogroup A （STT） and C （ST4821） Neisseria meningitides in Beijing, 2005.
