'Milestone' in meningococcal research: N meningitidis A genome sequenced.

Reports that the complete genome sequence of a serogroup A strain of Neisseria meningitidis, Z2491, has been determined. The international collaborative effort between the Sanger Centre in Cambridge, England, the Max-Planck Institute in Berlin, Germany, and the Wellcome Trust Centre in Oxford, England; Occurrence of repeat arrays suggesting that antigenic variation mediated by gene conversion might occur widely.
