Sequential bacteriological findings in the cerebrospinal fluid of Nigerian patients with pneumococcal meningitis.
Sequential bacteriological observations were made on the cerebrospinal fluid (CSF) of 28 patients with pneumococcal meningitis treated with high doses of penicillin for 2 weeks. The organism was isolated from the CSF of four patients 48 h or more after the start of treatment and from a further patient 48 h after treatment was stopped. Positive cultures were obtained in spite of the demonstration in the CSF of penicillin at a concentration well above the minimum inhibitory concentration for the organism isolated. Persistence of bacteria and their products in the CSF of patients with pneumococcal meningitis contrasts with the rapid clearance of bacteria from the CSF of patients with meningococcal meningitis and may contribute to the difference in the prognosis of these forms of meningitis.
