Microbiology
- Oxidase-positive, non-fermenting Gram negative bacillus
Mechanisms of Resistance
- Broad intrinsic and acquired antibiotic resistance
- Membrane impermeability
- MexAB-OprM efflux pump
- Acquired mutations
- Inducible AmpC β-lactamase
- Plasmid sharing
Environment and Infections
- Loves moist and wet environments
- Causes healthcare-associated infections
- UTI, SSI, bacteremia, HAP, VAP
- Especially common in cystic fibrosis
Treatment
- See Antipseudomonal antibiotics
- Double coverage (ß-lactam + non-ß-lactam) in cases of severe infection in order to ensure activity against the infection
