A survey of the meningococcal carrier rate was conducted in the Nsukka area (eastern Nigeria) during an interepidemic period. It was found that approximately 10% of 1126 individuals studied carried one serogroup or other. The predominant serogroup was B (58.1%), followed by C (24.2%). The highest percentage of isolates was from the age group 11-20 years (12.00%), followed by the age group 6-10 years (10.5%). The proportion of isolations was only 6.0% in the age group 31 years and above. Isolates from urban communities were resistant to sulfadiazine: 71.43% (group A), 63.9% (group B), 80.0% (group C), and 100% (group D). The percentage of resistant isolates from the villages was lower. Ninety-five per cent of all isolates were sensitive to penicillin, streptomycin, chloramphenicol, trimethoprim, and erythromycin.
在尼日利亚东部Nsukka地区的疾病流行间歇期，开展了一项脑膜炎球菌带菌率调查。结果发现，在接受研究的1126人中，约10%携带一种或多种血清群。主要血清群为B群（58.1%），其次是C群（24.2%）。分离株比例最高的年龄组为11 - 20岁（12.00%），其次是6 - 10岁年龄组（10.5%）。31岁及以上年龄组的分离株比例仅为6.0%。城市社区分离株对磺胺嘧啶耐药：A群为71.43%，B群为63.9%，C群为80.0%，D群为100%。来自农村的耐药分离株比例较低。所有分离株中有95%对青霉素、链霉素、氯霉素、甲氧苄啶和红霉素敏感。
