During 2003-2012, 8 clusters of meningococcal disease were identified in Rio de Janeiro State, Brazil, all caused by serogroup C Neisseria meningitidis. The isolates were assigned to 3 clonal complexes (cc): cc11, cc32, and cc103. These hyperinvasive disease lineages were associated with endemic disease, outbreaks, and high case-fatality rates.
2003 年至 2012 年期间,巴西里约热内卢州发现了 8 起脑膜炎球菌病群集,均由 C 群脑膜炎奈瑟菌引起。这些分离株被分为 3 个克隆复合体(cc):cc11、cc32 和 cc103。这些高侵袭性疾病谱系与地方性疾病、暴发和高病死率有关。
