General Susceptibility

Only these drugs are antipseudomonal:

  • Pip/Tazo

  • Ceftazidime

  • Cefepime

  • Meropenem

  • Imipenem

  • Aztreonam

  • Ciprofloxacin

  • Levofloxacin

  • Aminoglycosides

  • Colistin

Variable resistance patterns with mechanisms to be resistant to all of these drugs is observed, which is why double coverage is often used prior to susceptibility results.
