The distributions of zone diameter values for 19 antimicrobial agents. a Beta-lactams, macrolides, and pristinamycin. b Other agents. X-axis: diameter in millimeters; Y-axis: number of strains. The colors inside the bars represent the subset and geographic origins as in Fig. 1 (see key on b). The three background colors represent the categorical interpretations according to EUCAST: resistant (salmon, left), intermediate (lighter salmon, middle), and susceptible (pale beige, right). The gray vertical bar corresponds to the proposed tentative ecological cutoff
