| genetic structure of neisseria meningitidis serogroup c epidemic strains in south brazil. | in the present study we report the results of an analysis, based on serotyping, multilocus enzyme electrophoresis (mee), and ribotyping of n. meningitidis serogroup c strains isolated from patients with meningococcal disease (md) in rio grande do sul (rs) and santa catarina (sc) states, brazil, as the center of epidemiology control of ministry of health detected an increasing of md cases due to this serogroup in the last two years (1992-1993). we have demonstrated that the md due to n.meningitid ... | 1995 | 8599055 |
