Meningitis fulminante por Neisseria meningitidis serotipo W-135 y déficit de complemento

The Neisseria meningitidis serogroup W-135 has been involved in isolated cases of acute meningitis here in Spain. There is described the case of one American-born patient who is admitted with clinical manifestations of acute meningitis, and with N. meningitidis serotype W-135 being isolated in cerebrospinal fluid (CSF) culture.
