  4. cStat. Dif., Statistical significant differences. Countries with no statistical difference are marked with the same letter. Countries were compared by Fisher exact test with an alpha value of 0.05. Countries with less than ten tested isolates were not compared. Regarding MDR and FullS, only countries tested for all the considered antimicrobials were compared
  5. n, Total number of Escherichia coli tested for the considered antimicrobial category
  6. dMDR and FullS percentages do not include resistance to 3GC for Belgium and resistance to CN for the Netherlands
