Table 3 Antimicrobial resistance profile of enterococcal isolates to selected antimicrobial agents by species

From: Daptomycin exposure precedes infection and/or colonization with daptomycin non-susceptible enterococcus

Enterococcus species Proportion of isolates resistant to selected antimicrobial agents
  Daptomycin Vancomycin Ampicillin Linezolid
  (%) (%) (%) (%)
E. faecium (n = 18) 100 89 94 0
E. faecalis (n = 2) 100 50 0 0
Other (n = 5)a 100 20 20 5b
  1. NOTE:
  2. a – One Enterococcus isolate was identified as non-faecium / non-faecalis, and four were not available for species identification or linezolid susceptibility testing.
  3. b – Of the 21 patient isolates available for susceptibility testing; only the non-faecium / non-faecalis Enterococcus isolate was resistant to linezolid.
