[The effect of valinomycin and nigericin on the efficacy of bacteriophage infection of staphylococcal cells].

The effect of ionophore antibiotics, valinomycin and nigericin, on the generation of the membrane potential, the pH gradient and the efficacy of phage infection in tetracycline-resistant staphylococci has been studied. Valinomycin at a concentration of 0.5 microM induces the dissipation of the membrane potential, and nigericin at a concentration of 12.
