The MICs determined by Etest were a ≥1-fold dilution lower than those determined by broth microdilution and agar dilution, with the highest modal values given by agar dilution. The highest modal MICs were obtained using Oxoid medium, and the lowest inhibition zone values (disc diffusion) were obtained using Oxoid and bioMérieux media. The lowest MICs were obtained by Etest using Difco or Merck media. Torrico M, González N, Giménez MJ, Alou L, Sevillano D, Navarro D, Díaz-Antolín MP, Larrosa N, Aguilar L, Garcia-Escribano N.
