a MIC values were determined in cation-adjusted Mueller-Hinton broth (CAMB). b Concentration in µg/mL which inhibits the growth of 50% of the tested isolates. c Concentration in µg/mL which inhibits the growth of 90% of the tested isolates. d C-terminally carboxylated peptide form. e C-terminally amidated peptide form.
