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.<\/jats:p>","DOI":"10.1017\/s095026880005233x","type":"journal-article","created":{"date-parts":[[2009,5,15]],"date-time":"2009-05-15T08:34:17Z","timestamp":1242376457000},"page":"115-120","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":44,"title":["Epidemics of serogroup A<i>Neisseria meningitidis<\/i>of subgroup III in Africa, 1989\u201394"],"prefix":"10.1017","volume":"116","author":[{"given":"M.","family":"Guibourdenche","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.
