Six antineoplastic antibiotics showed little antibacterial activity against 28 strains of four species of gram-negative enteric bacteria. By using the cellophane transfer technique, combinations of these agents with 16 antibacterial drugs usually showed indifference. However, combinations of mitomycin C, especially with the aminoglycosides, were synergistic on strains of Escherichia coli, Proteus, and Klebsiella pneumoniae. Bleomycin, on the other hand, often showed antagonism on strains of E. coli and K. pneumoniae with the beta-lactams, aminoglycosides, and other antibacterial agents. Checkerboard titrations and kinetic killing curves confirmed these findings.
