Comparative in vitro activity of cefpirome and other antimicrobial agents against isolates from cancer patients.

Cefpirome and six other antimicrobial agents were tested against 884 blood culture isolates from cancer patients. Cefpirome was highly active against aerobic gram-negative bacilli including Acinetobacter spp., and the Enterobacteriaceae. Only imipenem was more active than cefpirome against Pseudomonas aeruginosa. Cefpirome was also extremely active against beta-hemolytic streptococci and methicillin-susceptible staphylococci.
