Abstract

Cefmenoxime, a new cephalosporin antibiotic, has been shown to be stable to a Staphylococcus aureus penicillinase and R plasmid-mediated type I and type IV penicillinases. It was also resistant to hydrolysis by most cephalosporinases, but was susceptible to hydrolysis by a Proteus vulgaris beta-lactamase. Cefmenoxime was active against cephaloridine-resistant species, except Pseudomonas aeruginosa, which was moderately resistant to cefmenoxime. Cefmenoxime was an inducer of P. vulgaris beta-lactamase biosynthesis, but 1 microgram or more of the drug per ml, which inhibits most of the clinical isolates of P. vulgaris, was required for the production of detectable amounts of the enzyme. Cefmenoxime was a strong competitive inhibitor of beta-lactamases of Enterobacter cloacae, Citrobacter freundii, P. aeruginosa, and Serratia marcescens, but it did not inhibit penicillinases in spite of its resistance to hydrolysis.
