- Enterococcus is part of normal gut flora
- Must cover both Enterococcus faecium and Enterococcus faecalis
Antimicrobial Options[1][2]
- Gentamicin 1 mg/kg q8hrs IV
- Use streptomycin for gentamicin resistance
- Add ampicillin 12 g q24hrs IV if treating endocarditis or vancomycin if suspicious for MRSA
- Linezolid 600 mg PO/IV q12hrs, with exception of bacteremia since agent is bacteriostatic
