MAIN EDUCATIONAL POINTS from GS154-2
- The Gram stain can provide rapid diagnostic information to clinicians.
- The information is useful both on the level of confirming a bacterial (rather than viral) cause of meningitis and indicating the probable bacterial species causing the infection.
- The Gram stain information may be useful to public health services if the culture is negative.
