Activities of oral antibiotics on Providencia strains isolated from institutionalized elderly patients with urinary tract infections

Abstract

More than 250 Providencia strains isolated from the urine of institutionalized elderly patients were tested against cefaclor, cefuroxime, cefetamet, cefpodoxime, ciprofloxacin, and amoxicillin-clavulanic acid. Our results confirm the strong activities of expanded-spectrum oral cephalosporins against Providencia isolates, f1p4ell as the marked differences in susceptibilities among accurately identified Providencia species.
