目的了解九江市庐山区健康人群流脑A群、C群抗体水平,为健康人群流脑A群、C群抗体水平监测工作提供指导。方法采集7个年龄组健康人群血清标本,各年龄组平均30人,共210人份,使用ELISA方法进行流脑A群和C群抗体的检测。结果各年龄组的A群抗体中,0～岁组抗体阳性率最低为42.85%;各年龄组C群抗体中,0～岁组抗体阳性率最低为35.71%,3～岁组抗体阳性率最高,在75%以上;流脑A群抗体阳性率高于C群。结论该区仍有部分人群抗体水平较低,对A群和C群流脑尚不具有免疫力,存在局部暴发流脑A群和C群的可能;有必要在大龄儿童及青少年中推广A+C流脑疫苗的接种。
Objective To understand the levels of antibody against group A and group C of the meningitis in healthy population in Lushan District, Jiujiang City, and provide guidance for the monitoring of antibody levels in Group A and Group C of healthy people. Methods Serum samples were collected from healthy population of seven age groups, with an average of 30 in each age group, with a total of 210 samples. The detection of meningococcal group A and C antibody was performed by ELISA. Results The lowest positive rate of antibody in group A was 42.85% in group A antibody in all age groups. The lowest positive rate of antibody in group C was 35.71% in group C at the age of 0 ~ , Above 75%. The positive rate of meningococcal group A antibody was higher than that of C group. Conclusion There are still some people in this area with low antibody level, which are not immune to group A and group M meningitis. There is a possibility that outbreak of part A and group C of meningitis may occur. It is necessary to promote A + C meningitis vaccine inoculation.
