  • Title: Efficacy of cefmenoxime in experimental group B streptococcal bacteraemia and meningitis.
    Author: Kim KS.
    Journal: J Antimicrob Chemother; 1986 Feb; 17(2):239-44. PubMed ID: 3516964.
    Abstract:
    Cefmenoxime, a new semisynthetic cephalosporin, was evaluated in vitro and in vivo in comparison with penicillin G against a type III group B streptococcal strain. In vitro, the minimal inhibitory and minimal bactericidal concentrations of the two drugs were very close (less than or equal to 2 dilutions). In-vivo studies using experimental bacteraemia and meningitis in newborn rats revealed that despite similar drug levels, cefmenoxime had significantly greater bactericidal titres in blood at 6-7 h after administration and bacterial clearance from blood was significantly faster with cefmenoxime than with penicillin G at the end of one day of treatment. In addition, all animals with cefmenoxime therapy had bactericidal titres in cerebrospinal fluid greater than or equal to 1:8 at 1-2 h after administration, whereas most (67%) animals receiving penicillin G had titres less than 1:8. However, overall efficacy of cefmenoxime was similar to that of penicillin G. These findings suggest that cefmenoxime may be an effective alternative against group B streptococcal infection.
