"Pansusceptible" isolates are sensitive to:

• Ampicillin

• Cephalosporins including first generation

• TMP-SMX

• Fluoroquinolones

• Broader spectrum beta-lactams

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

Use fosfomycin and nitrofurantoin for UTI only.
