RESUMO
Cefuroxime, a new parenteral cephalosporin was compared with cephalothin by broth microdilution susceptibility testing against 5,887 routine clinical bacterial isolates in four large clinical laboratories. The minimal inhibitory concentrations (MICs) of cefuroxime against the Enterobacteriaceae were consistently lower than those of cephalothin. This was most striking among the Enterobacter species, which were generally susceptible to cefuroxime (MIC ≤ 8 μg/ml), but resistant to cephalothin. Similar results occurred with Haemophilus species, Acinetobacter anitratus, meningococci, and Aeromonas hydrophilia, but Pseudomonas species and enterococci were resistant to high concentrations of both drugs. Streptococci showed slightly greater susceptibility to cefuroxime than to cephalothin. By contrast, staphylococci were more susceptible to cephalothin. Bacteroides fragilis was resistant to cefuroxime, but other anaerobes were generally susceptible.
