Abstract

A total of 125 strains of Neisseria meningitidis recovered in the course of outbreaks from patients with systemic disease in 11 African countries between 1989 and 1994 were analysed by serogrouping, serotyping and multilocus enzyme electrophoresis. Of the 125 patient strains 115 (92%) belonged to the clone-complex of serogroup A meningococci, designated subgroup III. Among the remaining strains, 4 were also serogroup A, but belonged to the clonal groups I and IV-1 (2 strains each), whilst 6 strains (4 serogroup C and 2 serogroup W135) represented clones of the ET-37 complex. Our results indicated that the second pandemic caused by clones of subgroup III is still spreading in Africa. Towards the West it has reached Niger, Mali, Guinea and The Gambia, and towards the South, the Central African Republic, Uganda, Rwanda, Burundi, Tanzania and Zambia.

摘要

对1989年至1994年间在11个非洲国家从患有全身性疾病的患者身上分离出的125株脑膜炎奈瑟菌进行了血清群分类、血清型分型和多位点酶电泳分析。在这125株患者菌株中,115株(92%)属于A群脑膜炎球菌的克隆复合体,称为III亚组。在其余菌株中,4株也是A群,但属于克隆群I和IV-1(各2株),而6株(4株C群和2株W135群)代表ET-37复合体的克隆。我们的结果表明,由III亚组克隆引起的第二次大流行仍在非洲蔓延。向西已蔓延至尼日尔、马里、几内亚和冈比亚,向南已蔓延至中非共和国、乌干达、卢旺达、布隆迪、坦桑尼亚和赞比亚。
