[Bacterial meningitis]

After a presentation of purulent and liquoral bacterial meningites with an examination of their pathogenesis, a personal case series is presented. Particular attention is paid to the liquoral transfer of antibiotics and it is considered that the treatment of purulent bacterial meningitis cannot be standardised. In contrast tubercolar meningitis can be subjected to standardised treatment. Currently the results obtained in the treatment of purulent bacterial meningitis are less satisfactory than those obtained in tubercular meningitis though certainly better than in the recent past.
