The objective of this study was to evaluate the in vitro activity of cefepime, cefpirome and amikacin against the most prevalent nosocomial bacteria. Initially a prospective study was designed to compare the bacterial susceptibility to the three drugs using 1,022 pathogenic strains. The strains were isolated from hospitalized patients of the Hospital das Clinicas - Faculdade de Medicina de Botucatu, SP, from March to December of 1996, by using the Bauer-Kirby susceptibility diffusion controlled method. The activity of cefepime by the Kirby-Bauer method was significantly higher (χ2, p ≤ 0.05) than cefpirome and amikacin for the following bacteria: P. aeruginosa (72% x 56% x 64%, respectively), Enterobacter cloacae (98% x 88% x 80%) and total strains (79.5% x 74.3% x 76.8%). Cefpirome exhibited higher activity than cefepime only to Enterococcus faecalis (42% x 23%). In the 12 other bacterial groups studied the sensibility of the three drugs was similar (χ2, p ≥ 0.05). The minimal inhibitory concentration (MIC) for 127 bacterial strains - Enterobacter cloacae (12), Citrobacter sp (15), Pseudomonas aeruginosa (50), Acinetobacter baumannii (12), BGNF others (22) and Enterococcus faecalis (16)-from the same origin previously described and isolated during 1997, was determined by E-test. Ranges of MIC intervals, MIC(50%), MIC(90%) and the proportion of the sensitive bacterial strains were determined and permitted the following analysis: the activity of cefepime against Gram-negative bacteria was 2 or more times higher than that of cefpirome and amikacin, specially when CIM(90%) was considered; the activity of cefpirome was higher only against E. faecalis. This information must be considered in the rational use of antibiotic, specially in patients with nosocomial infections.
