  1. Breakpoints are employed according to VET01S document
  2. MIC50, lowest concentration to inhibit 50% of bacteria; MIC90, lowest concentration to inhibit 90% of bacteria
  3. R Resistant, I Intermediate, S Susceptible, MIC Minimum inhibitory concentration
  4. aOnly CLSI breakpoint for dog isolates available
  5. bThe breakpoints derived from human breakpoints used [18]
