Mutations in ribosomal protein L16 and in 23S rRNA were investigated in 22 Enterococcus strains of different species and for which the MICs of evernimicin differ (MICs, 0.023 to 16 μg/ml). Amino acid changes (Arg56His, Ile52Thr, or Arg51His) in protein L16 were found in seven strains, and a nucleotide G2535A mutation in 23S rRNA was found in 1 strain among 13 for which the MICs are ≥1 μg/ml.
