Synergism between gentamicin and mitomycin C in staphylococcal infections in mice

Mitomycin C, an antineoplastic antibiotic, and gentamicin showed a dose-related protective effect in mice against a lethal staphylococcal infection when used singly. A combination of these two drugs was shown to be synergistic in the mouse model. A specific logistic regression analysis method confirmed that a synergistic bactericidal effect was obtained with the combination.
