title: [Epidemiological notes: meningococcal meningitis of serogroup X in Niamey (Niger)].
abstract: From 19th February to 15th April 1990, 22 strains of meningococcus belonging to serogroup X have been identified by the Centre for Study and Research on meningitidis and Schistosomiases (CERMES) at Niamey (Niger). Serogroup X has been confirmed by the Centre Collaborating WHO of Reference and Training for Meningococci (CCOMSRFM) at Marseille (France). These strains have been isolated from cerebrospinal fluid of patients suffering from cerebrospinal meningitis and living in different neighbourhoods of Niamey. Apparition of cases of meningococcal meningitis with other serogroups than A implies identification of serogroup of meningococcus in intertropical Africa.
