Antimicrobial spectrum of Ro 15-8074/001, a new oral cephalosporin

Abstract

The activity of Ro 15-8074/001 was compared with that of cefaclor, amoxicillin-clavulanic acid, trimethoprim-sulfamethoxazole, norfloxacin, and ceftriaxone against 225 clinical isolates. It was more active than cefaclor, amoxicillin-clavulanic acid, and trimethoprim-sulfamethoxazole against members of the family Enterobacteriaceae and Haemophilus influenzae and had activity similar to that of cefaclor against nonenterococcal streptococci. It was not usefully active against Pseudomonas aeruginosa, Streptococcus faecalis, or most isolates of staphylococci.
