Antibiotic sensitivity overview Appendix 5


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.
- C. difficile should only be treated with metronidazole or vancomycin
- ESCHAPPM are β-lactamase producing organisms. These are Enterobacter, Serratia, Citrobacter freundii, Hafnia, Acinetobacter/Aeromonas, Proteus (not mirabilis), Providencia & Morganella morganii
- Not effective against Clostridium
- Metronidazole is not effective against Peptostreptococcus
- Teicoplanin is not effective against Enterococcus faecium
- Gentamicin is not appropriate mono therapy for Staphylococcus aureus & should only be used in conjunction with a β-lactam
- Due to increasing MIC, Cefuxorime is not recommended therapy for Moraxella
- Although it has other actions, Ceftazidime should only be used for Pseudomonas
