Background

Cefoxitin is a cephalosporin antibiotic.¹ It is active against numerous Gram-negative bacteria, including strains of P. mirabilis, P. vulgaris, E. coli, S. typhimurium, and S. enteritidis (MICs = 4-32 ?g/ml for all). It binds to B. subtilis penicillin-binding protein 2a (PBP2a), -2b, -3, -4, and -5 (IC₅₀s = 0.72, 0.19, 1.04, 0.14, and 0.19 ?g/ml, respectively).² Cefoxitin increases survival in mice infected with S. aureus, S. pyogenes, or K. pneumoniae (ED₅₀s = 250, 63, and 795 ?g/animal, respectively).¹ Formulations containing cefoxitin have been used in the treatment of bacterial infections.
