Viridans group streptococci: Difference between revisions

Latest revision as of 17:49, 19 September 2024

Background

Microbiology

Gram-positive cocci
Commensal oral flora

Species

Streptococcus anginosus group (previously milleri group): most likely to cause invasive pyogenic infections similar to Staphylococcus aureus
Streptococcus mitis group
- Streptococcus mitis
- Streptococcus oralis
Streptococcus sanguinis group
Streptococcus salivarius group
Streptococcus mutans group
- Streptococcus mutans

Management

Penicillin non-susceptibility varies by species
- Streptococcus salivarius group is 80% non-susceptible (in Korea1)
- Streptococcus mitis group is 60%
- Streptococcus sanguinis group is 40%
- Streptococcus anginosus group is 6%
