Viridans streptococci and S. bovis/S. equinus complex — Members of the viridans group include S. mitis, S. mutans, S. oralis, S. sanguinis, S. sobrinus, and the S. milleri group (S. anginosus, S. constellatus, and S. intermedius).

The nomenclature of the S. bovis/S. equinus complex is summarized in the table (table 3). (See "Infections due to g...

Viridans streptococci and S. bovis/S. equinus complex — Members of the viridans group include S. mitis, S. mutans, S. oralis, S. sanguinis, S. sobrinus, and the S. milleri group (S. anginosus, S. constellatus, and S. intermedius).

The nomenclature of the S. bovis/S. equinus complex is summarized in the table (table 3). (See "Infections due to group D streptococci (Streptococcus bovis/Streptococcus equinus complex)".)

The MIC breakpoints differ between the guidelines published by the AHA, British Society for Antimicrobial Chemotherapy (BSAC), and ESC; the MIC breakpoints are summarized in the tables (table 4 and table 5).

Penicillin-susceptible strains — MIC breakpoints and treatment regimens for endocarditis due to highly penicillin-susceptible streptococci are summarized in the table (table 4) [1-3].

For treatment of patients with NVE due to highly penicillin-susceptible streptococci (defined by the AHA as MIC ≤0.12 mcg/mL), we are in agreement with the AHA and ESC which favor aqueous crystalline penicillin G (12 to 18 million units daily for four weeks) or ceftriaxone (2 g per day) for four weeks [1,2].
