Plus–minus values are means ±SD.
The Glasgow Coma Scale ranges from 3 to 15, with 3 indicating that the patient is unresponsive and 15 indicating that the patient is fully alert.
Details regarding pretreatment antibiotics are available in Table S1 in the Supplementary Appendix.
Other gram-negative organisms were Escherichia coli (in 11 patients), non-typhi salmonella (in 7), Haemophilus influenzae (in 3), klebsiella species (in 3), and Enterobacter gergoviae (in 1).
Other bacteria were Staphylococcus aureus (in 2 patients) and α-hemolytic streptococci (in 3).
Of 20 patients, 10 were categorized as having probable bacterial meningitis on the basis of the cell and differential counts from the cerebrospinal fluid specimen but were found to have cryptococcal meningitis either after prolonged incubation or after repeated lumbar puncture.
Of 150 positive blood cultures, 7 were positive for Cryptococcus neoformans.
