General Susceptibility

"Pansusceptible" isolates are sensitive to:

  • Ampicillin
  • Cephalosporins
  • TMP-SMX
  • Fluoroquinolones
  • Broader spectrum beta-lactams

May be resistant to third generation cephalosporins (ESBLs), and rarely to carbapenems (carbapenemase enzymes).

Use fosfomycin for UTI only.
