Partial columns indicate incomplete coverage

For simplicity, atypical organisms are not included above. Partial columns indicate incomplete coverage. ESBL-producing organisms are not susceptible to most antibiotics containing a beta-lactam ring; carbapenems are the usual agent of choice.

  1. C. difficile should only be treated with metronidazole or vancomycin

  2. ESCHAPPM are β-lactamase producing organisms. These are Enterobacter, Serratia, Citrobacter freundii, Hafnia, Acinetobacter/Aeromonas, Proteus (not mirabilis), Providencia & Morganella morganii

  3. Not effective against Clostridium

  4. Metronidazole is not effective against Peptostreptococcus

  5. Teicoplanin is not effective against Enterococcus faecium

  6. Gentamicin is not appropriate mono therapy for Staphylococcus aureus & should only be used in conjunction with a β-lactam

  7. Due to increasing MIC, Cefuxorime is not recommended therapy for Moraxella

  8. Although it has other actions, Ceftazidime should only be used for Pseudomonas
