Background

  • Cause of ileocecitis
  • Appendicitis mimic

Clinical

  • N/V/D
  • Abd pain
  • Fever
  • A smaller percentage will have pain and fever alone (mimicking appendicitis)

Treatment

  • Tends to be self limiting
  • IVF if needed, pain control, fever control

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
