- Streptococci of groups C and G cause infections similar to those caused by GAS, including cellulitis, bacteremia (particularly in elderly or chronically ill pts), pneumonia, and soft tissue infections.
- Strains that form small colonies (<0.5 mm) on blood agar are generally of the S. milleri group (S. intermedius, S. anginosus); large-colony groups C and G streptococci are now considered a single species (S. dysgalactiae subsp. equisimilis).
- Treatment is the same as for similar syndromes due to GAS.
- - Although it has not been shown to be superior, the addition of gentamicin (1 mg/kg IV q8h) is recommended by some experts for endocarditis or septic arthritis due to group C or G streptococci because of a poor clinical response to penicillin alone.
- - Joint infections can require repeated aspiration or open drainage for cure.
