Background

The majority of Klebsiella infections are caused by K. pneumoniae, followed by K. oxytoca.

Characteristics

  • Gram-negative rod
  • Facultative anaerobe
  • Lactose-fermenting
    • Grows pink on MacConkey agar
  • Urease positive

Key

  • S susceptible/sensitive (usually)
  • I intermediate (variably susceptible/resistant)
  • R resistant (or not effective clinically)
  • S+ synergistic with cell wall antibiotics
  • U sensitive for UTI only (non systemic infection)
  • X1 no data
  • X2 active in vitro, but not used clinically
  • X3 active in vitro, but not clinically effective for Group A strep pharyngitis or infections due to E. faecalis
  • X4 active in vitro, but not clinically effective for strep pneumonia
