dc.description.abstract The in vitro activity of cefepime was compared to that of ceftazidime, ceftriaxone, and cefotaxime in a multicenter study involving 10 clinical microbiology laboratories and clinical isolates from 18 Brazilian hospitals from 7 cities (4 states). A total of 982 isolates consecutively collected between December 1995 and March 1996 were susceptibility tested by using Etest and following the NCCLS procedures for agar diffusion tests. the cefepime spectrum was broader than that of the other broad-spectrum cephalosporins against both Gram-negative rods and Gram-positive cocci. Cefepime tons particularly move active against Enterobacter sp. (MIC90, 2 mu g/ml), Serratia sp. (MIC90, 2 mu g/ml) and oxacillin-susceptible Staphylococcus aureus (MIC90, 3 mu g/ml). Against Pseudomonas aeruginosa, cefepime (MIC90 16 mu g/ml) was slightly more active than ceftazidime (MIC90 32 mu g/ml) and 8- to 16-fold more active than ceftriaxone or cefotaxime (MIC90 >256 mu g/ml). Our results show that nosocomial bacteria, especially Gram-negative rods, have a high rate of cephalosporin resistance in Brazil. However, part of these resistant bacteria remains susceptible to cefepime. the Etest was shown to be an excellent method for multicenter studies of the in vitro evaluation of new antimicrobial agents.
