Abstract: 目的 了解2013-2014年高密市健康人群流行性脑脊髓膜炎带菌状况,为预防控制流脑提供科学依据.方法 按分层随机抽样方法,在全市范围于流脑流行前期、流行期和流行末期采集7个年龄组健康人群咽拭子996份,现场接种巧克力双抗平板分离培养后,进行染色镜检、生化鉴定及血清凝集分型.结果 咽拭子脑膜炎奈瑟氏菌阳性检出8份,带菌率0.80%;菌株分别为A、B、C、W135群,其中A群4株,占50%.1~3岁、7~15岁儿童流脑带菌率最高,分别为3.42%、2.07%,各年龄组带菌率差异有统计学意义(P<0.05).各镇街人群带菌率以拒城河镇和密水街办为最高,分别为1.81%和1.22%,各镇街差异均无统计学意义.结论 高密市健康人群流脑带菌率为0.80%,1~3岁和7~15岁人群流脑带菌率较高,A群流脑菌群是主要流行株.
