  1. Data from the 2013 European Antimicrobial Resistance Surveillance Network report, www.ecdc.europa.eu/en/publications/Publications/antimicrobial-resistance-surveillance-europe-2013.pdf. Invasive infections are bacteraemia or meningitis
  2. AMC Amoxicillin plus clavulanic acid, TZP Piperacillin-tazobactam, CRO Ceftriaxone, IMP Imipenem, CIP Ciprofloxacin, GM Gentamicin, SXT Trimethoprim-sulphamethoxazole, FT Furan
  3. aThe number of K. pneumoniae strains were estimations based on data presented in the 2013 European Antimicrobial Resistance Surveillance Network report for the other European countries from 2010 to 2013. These calculations were based on the maximum of strains tested for antibiotic susceptibility testing for every year from 2010 to 2013
  4. bAnalyses performed using Pearson Chi Square or Fisher exact tests as appropriate (two-sided tests, p value <0.05 considered as statistically significant). Statistical tests were performed comparing the number of invsiave K. pneumoniae strains resistant to ceftriaxone, imipenem, ciprofloxacin and gentamicin in our study to that of the different countries included in the 2013 European Antimicrobial Resistance Surveillance Network report
