  • Title: Cefuroxime, a beta-lactamase-resistant cephalosporin with a broad spectrum of gram-positive and -negative activity.
    Author: Neu HC, Fu KP.
    Journal: Antimicrob Agents Chemother; 1978 Apr; 13(4):657-64. PubMed ID: 248268.
    Abstract:
    The in vitro activity of cefuroxime, a cephalosporin antibiotic, was investigated against 604 isolates and compared with the activity of other beta-lactam compounds. Cefuroxime had activity comparable to that of other cephalosporins, including cefamandole and cefoxitin, against streptococcal and staphylococcal species; most streptococci were inhibited by 0.1 mug or less per ml, and staphylococci were inhibited by 1.6 mug or less per ml. Enterococci were relatively resistant. Cefuroxime inhibited beta-lactamase-producing Neisseria gonorrhoeae and Haemophilus influenzae. Cefuroxime had excellent activity against members of the Enterobacteriaceae; 83% of beta-lactamase-producing Escherichea coli, 100% of Salmonella, 100% of Klebsiella, 90% of Proteus mirabilis, 95% of Citrobacter, 56% of Enterobacter, and 58% of Shigella were inhibited by 12.5 mug/ml. Cefuroxime had activity comparable to that of cefamandole and cefoxitin; it inhibited isolates of E. coli and Klebsiella resistant to cefamandole and inhibited Enterobacter and Citrobacter resistant to cefoxitin. Many isolates of Serratia, some indole-positive strains of Proteus, and Bacteroides fragilis were resistant to cefuroxime. Resistance of cefuroxime to hydrolysis by beta-lactamases played a major role in its activity against both gram-positive and gram-negative organisms.
