Those considered CRITICAL in terms of Research and Development for new antibiotics

  • Pseudomonas aeruginosa, carbapenem-resistant
  • Enterobacteriaceae, carbapenem-resistant, ESBL-producing
  • Acinetobacter baumannii, carbapenem-resistant

Six are considered to be of high priority:

  • Enterococcus faecium, vancomycin-resistant
  • Staphylococcus aureus, methicillin-resistant, vancomycin-intermediate and resistant
  • Helicobacter pylori, clarithromycin-resistant
  • several species of Campylobacter, fluoroquinolone-resistant
  • Salmonellae, fluoroquinolone-resistant
  • Neisseria gonorrhoeae, cephalosporin-resistant, fluoroquinolone-resistant

Three are deemed to be of medium priority:

  • Streptococcus pneumoniae, penicillin-non-susceptible
  • Haemophilus influenzae, ampicillin-resistant
  • several species of Shigella, fluoroquinolone-resistant
