Herein we present a case of Neisseria meningitidis-related sepsis and meningitis in a 60- year-old woman. The N. meningitidis strain was identified as serogroup B and sequence type (ST)-4893 by multilocus sequence typing (MLST). The patient in this case had visited France prior to development of symptoms. No meningococcal isolate belonging to ST-4893 has been identified in Japan previously, whereas an ST-4893 strain from France has been reported in the MLST database. These results strongly suggest that this case is likely to have been imported from France.
