Answer

Most S bovis isolates are susceptible to penicillin (MIC ≤ 0.1 mg/L) and should be treated with intravenous penicillin G or ceftriaxone for 4 weeks. An alternative for only uncomplicated cases of native-valve endocarditis is a 2-week course of therapy with a combination of penicillin G or ceftriaxone and gentamicin. For moderately susceptible isolates (MIC >0.1 mg/L, MIC ≤ 0.5 mg/L), penicillin or ceftriaxone and gentamicin should be administered for 4 weeks and 2 weeks, respectively. [16]
