PATHOGENS
- S. pneumoniae
- N. meningitidis
- Listeria monocytogenes
- Haemophilus influenzae
- Streptococcus agalactiae (Group B Streptococcus, GBS)
- Enterococcus (uncommon)
- For community-acquired bacterial meningitis, Streptococcus pneumoniae and Neisseria meningitidis are responsible for usually 80% of all adult cases.
- The overall species-specific infection rates (all ages, 1997-2008 data[8]):
- Rates of community-acquired infection with specific pathogens strongly influenced by age.
- Children and young adults 2-29 yrs: N. meningitidis 60%, S. pneumoniae 27%, group B Streptococcus 5%, H. influenzae 5%, L. monocytogenes 2%
- Adults 30-59 yrs: S. pneumoniae 61%, N. meningitidis 18%, H. influenzae 12%, L. monocytogenes 2%
- Adults > 60 yrs: S. pneumoniae 61%, N. meningitidis 18%, H. influenzae 12%, L. monocytogenes 6%, Group B Streptococcus 3%
