There is an error in Table 1. The bold vertical lines denoting epidemiological cut-off values for resistance are missing. The publisher apologizes for the error. Please see the correct Table 1 here.

Bold vertical lines denote epidemiological cut-off values for resistance. NA, cut-off not defined by EUCAST. White fields denote range of dilutions tested for each antimicrobial agent. MIC values higher than the highest concentration tested are given as the lowest MIC value above the range. MIC values equal to or lower than the lowest concentration tested are given as the lowest concentration tested.
