Numeric data represent local susceptibility data.
(+) = usually effective or >60% susceptible; (+/-) = clinical trials lacking or 30-60% susceptible; (-) = not effective clinically or <30% susceptible - Adapted with permission from The Sanford Guide to Antimicrobial Therapy
(*) Local (non-Sanford Guide) opinion
(S) = synergistic with penicillin/ampicillin
(&) nitrofurantoin only useful for lower tract urinary tract infections
