  1. Susceptibility to antibiotics was tested by incubation of bacteria together with antibiotic disks for 48 h on Mueller–Hinton agar and results were interpreted using the breakpoints for zone diameters of the European Committee on Antimicrobial Susceptibility Testing (EUCAST, http://www.eucast.org)
