S pneumoniae, a gram-positive coccus, is the most common bacterial cause of meningitis. In addition, it is the most common bacterial agent in meningitis associated with basilar skull fracture and cerebrospinal fluid (CSF) leak. It may be associated with other focal infections, such as pneumonia, sinusitis, or endocarditis (as, for example, in Austrian syndrome, which is the triad of pneumococcal meningitis, endocarditis, and pneumonia).
