The CSF samples will be stored at -80°C until testing . CSF specimens will be prepared for GS and culture examinations by centrifugation at 3,000 rpm for 10 minutes at room temperaturetemperature.Culture will be performed by inoculating 1-2 drops of CSF sediment directly onto each of the following agar plates: horse-blood agar, Thayer-Martin agar, choc- olate agar and Sabouraud agar. Moreover, a broth tube (brain-heart infusion, BHI) will be inoculated with one drop of the sediment. Agar plates and broth will be incubated for 1 to 5 days at 35-37°C (with ~5% CO2, or in a candle-jar, for Thayer-Martin and chocolate agar) .
In addition to GS and culture method , India ink test and culture and latex agglutination test (LAT). LAT assay will be performed on CSF samples using Latex-antigen detection system kit..

The CSF samples will be stored at -80°C until testing . CSF specimens will be prepared for GS and culture examinations by centrifugation at 3,000 rpm for 10 minutes at room temperature. When dry, the smear will be fixed stained and finally observed by light microscopy with a 100X objective. Culture will be performed by inoculating 1-2 drops of CSF sediment directly onto each of the following agar plates: horse-blood agar, Thayer-Martin agar, choc- olate agar and Sabouraud agar. Moreover, a broth tube (brain-heart infusion, BHI) will be inoculated with one drop of the sediment. Agar plates and broth will be incubated for 1 to 5 days at 35-37°C (with ~5% CO2, or in a candle-jar, for Thayer-Martin and chocolate agar) .
