Comparison of Activities of Broad-Spectrum
-Lactam Compounds
against 1,128 Gram-Positive Cocci Recently Isolated in Cancer
Treatment Centers
-lactam
antimicrobials tested against 1,128 gram-positive pathogens recently isolated from cancer patients. Cefepime and imipenem were more active
than ceftazidime and ceftriaxone against these organisms. Only
vancomycin demonstrated reliable activity against oxacillin-resistant staphylococci, Enterococcus spp., and
Corynebacterium spp. The spectrum of gram-positive
organisms against which cefepime and imipenem have activity provides an
advantage over ceftazidime as empiric therapy for cancer patients,
potentially reducing the need for the empiric addition of glycopeptides.
