Aggregated MIC distributions of Arcobacter spp. isolated from food, environmental water and human stool samples. In addition to the MICs of the Arcobacter spp. strains (blue) isolated in our study, the epidemiological cut-off values (ECOFFs) (red broken lines) and MICs of C. jejuni (orange) from the EUCAST database are also shown [29]. E-test half-log values were rounded up to the next highest value of the standard doubling dilution scale. In order to prevent numerical dominance of EUCAST MIC distributions, number of isolates at each MIC value are presented as percentage of the total observations from individual dataset
