温州市流行性脑脊髓膜炎监测分析

Surveillance analysis of epidemic cerebrospinal meningitis in Wenzhou

  • 摘要: 目的 了解浙江省温州市流行性脑脊髓膜炎(流脑)带菌状况,菌群分布,耐药特性和免疫抗体水平等情况,从而为合理制定有效的预防措施提供依据.方法 按流脑监测方案,选择温州市鹿城区、瓯海区作为监测点,采集各年龄组健康人群咽拭子接种含双抗的巧克力色血琼脂进行脑膜炎奈瑟菌(Nm)分离培养,鉴定和药敏试验,同时采集血液分离血清用间接酶联免疫吸附试验(ELISA)法检测流脑A群和C群抗体.结果 检出C群流脑患者1例(男,20岁);健康人群Nm的带菌率为2.98%(10/336);健康人群流脑A群抗体的总阳性率47.09%(81/172),健康人群流脑C群抗体总阳性率35.47%(61/172).结论 流脑的发病率低和健康人群Nm的带菌率低,大部分人对A群流脑有免疫力有关,而对C群流脑的免疫力低,有必要加强A+C群流脑疫苗的接种,同时应密切注视流脑菌群的变迁,关注不同血清群菌株耐药性变化.

     

    Abstract: Objective This study was conducted to gain insight into the germ-carrying situation, bacterial distribution,drug resistance and immune antibody level of epidemic cerebrospinal meningitis (ECM)in Wenzhou,Zhejiang for effective prevention of ECM.Methods Lucheng and Ouhai were chosen as the monitoring sites according to the ECM monitoring program.Pharynx swab samples col- lected from healthy people of different ages were inoculated to the double-anti-chocolate-colored blood agaragar for the isolating culture,identification and antimicrobial susceptibility test for Neisseria Meningitidis(Nm).Collected sera were detected the serogroup A and C specific IgG antibody by ELISA.Results One case of serogroup C(male,20 years old)was detected.The Nm carder rate a- mong healthy crowd was 2.98%(10/336);the positive rate of serogroup A antibody among healthy crowd 47.09%(81/172)and serogroup C antibody 35.47%(61/172).Conclusion The incidence rate of epidemic cerebrospinal meningitis and the Nm carrier rate were low.Most people had high immunity to the A group of epidemic cerebrospinal meningitis albeit low to the C group.It is necessary to strengthen the vaccination of A+C group of epidemic cerebrospinal meningitis with close attention paid to the colony diversification and the alteration of resistant swains of different serums groups.
